text: Down syndrome cell adhesion molecule 1 (Dscam1) has widereaching and vital
neuronal functions although the role it plays in insect and crustacean immunity
is less well understood. In this study, we combine different approaches to understand
the roles that Dscam1 plays in fitness-related contexts in two model insect species.
Contrary to our expectations, we found no short-term modulation of Dscam1 gene
expression after haemocoelic or oral bacterial exposure in Tribolium castaneum,
or after haemocoelic bacterial exposure in Drosophila melanogaster. Furthermore,
RNAi-mediated Dscam1 knockdown and subsequent bacterial exposure did not reduce
T. castaneum survival. However, Dscam1 knockdown in larvae resulted in adult locomotion
defects, as well as dramatically reduced fecundity in males and females. We suggest
that Dscam1 does not always play a straightforward role in immunity, but strongly
influences behaviour and fecundity. This study takes a step towards understanding
more about the role of this intriguing gene from different phenotypic perspectives.

text: The rare socially parasitic butterfly Maculinea alcon occurs in two forms,
which are characteristic of hygric or xeric habitats and which exploit different
host plants and host ants. The status of these two forms has been the subject
of considerable controversy. Populations of the two forms are usually spatially
distinct, but at Răscruci in Romania both forms occur on the same site (syntopically).
We examined the genetic differentiation between the two forms using eight microsatellite
markers, and compared with a nearby hygric site, Şardu. Our results showed that
while the two forms are strongly differentiated at Răscruci, it is the xeric form
there that is most similar to the hygric form at Şardu, and Bayesian clustering
algorithms suggest that these two populations have exchanged genes relatively
recently. We found strong evidence for population substructuring, caused by high
within host ant nest relatedness, indicating very limited dispersal of most ovipositing
females, but not association with particular host ant species. Our results are
consistent with the results of larger scale phylogeographic studies that suggest
that the two forms represent local ecotypes specialising on different host plants,
each with a distinct flowering phenology, providing a temporal rather than spatial
barrier to gene flow.

text: 'Summary: Declining populations of bee pollinators are a cause of concern,
with major repercussions for biodiversity loss and food security. RNA viruses
associated with honeybees represent a potential threat to other insect pollinators,
but the extent of this threat is poorly understood. This study aims to attain
a detailed understanding of the current and ongoing risk of emerging infectious
disease (EID) transmission between managed and wild pollinator species across
a wide range of RNA viruses. Within a structured large-scale national survey across
26 independent sites, we quantify the prevalence and pathogen loads of multiple
RNA viruses in co-occurring managed honeybee (Apis mellifera) and wild bumblebee
(Bombus spp.) populations. We then construct models that compare virus prevalence
between wild and managed pollinators. Multiple RNA viruses associated with honeybees
are widespread in sympatric wild bumblebee populations. Virus prevalence in honeybees
is a significant predictor of virus prevalence in bumblebees, but we remain cautious
in speculating over the principle direction of pathogen transmission. We demonstrate
species-specific differences in prevalence, indicating significant variation in
disease susceptibility or tolerance. Pathogen loads within individual bumblebees
may be high and in the case of at least one RNA virus, prevalence is higher in
wild bumblebees than in managed honeybee populations. Our findings indicate widespread
transmission of RNA viruses between managed and wild bee pollinators, pointing
to an interconnected network of potential disease pressures within and among pollinator
species. In the context of the biodiversity crisis, our study emphasizes the importance
of targeting a wide range of pathogens and defining host associations when considering
potential drivers of population decline.'

text: Emerging infectious diseases (EIDs) have contributed significantly to the
current biodiversity crisis, leading to widespread epidemics and population loss.
Owing to genetic variation in pathogen virulence, a complete understanding of
species decline requires the accurate identification and characterization of EIDs.
We explore this issue in the Western honeybee, where increasing mortality of populations
in the Northern Hemisphere has caused major concern. Specifically, we investigate
the importance of genetic identity of the main suspect in mortality, deformed
wing virus (DWV), in driving honeybee loss. Using laboratory experiments and a
systematic field survey, we demonstrate that an emerging DWV genotype (DWV-B)
is more virulent than the established DWV genotype (DWV-A) and is widespread in
the landscape. Furthermore, we show in a simple model that colonies infected with
DWV-B collapse sooner than colonies infected with DWV-A. We also identify potential
for rapid DWV evolution by revealing extensive genome-wide recombination in vivo.
The emergence of DWV-B in naive honeybee populations, including via recombination
with DWV-A, could be of significant ecological and economic importance. Our findings
emphasize that knowledge of pathogen genetic identity and diversity is critical
to understanding drivers of species decline.

text: Emerging infectious diseases (EIDs) have contributed significantly to the
current biodiversity crisis, leading to widespread epidemics and population loss.
Owing to genetic variation in pathogen virulence, a complete understanding of
species decline requires the accurate identification and characterization of EIDs.
We explore this issue in the Western honeybee, where increasing mortality of populations
in the Northern Hemisphere has caused major concern. Specifically, we investigate
the importance of genetic identity of the main suspect in mortality, deformed
wing virus (DWV), in driving honeybee loss. Using laboratory experiments and a
systematic field survey, we demonstrate that an emerging DWV genotype (DWV-B)
is more virulent than the established DWV genotype (DWV-A) and is widespread in
the landscape. Furthermore, we show in a simple model that colonies infected with
DWV-B collapse sooner than colonies infected with DWV-A. We also identify potential
for rapid DWV evolution by revealing extensive genome-wide recombination in vivo.
The emergence of DWV-B in naive honeybee populations, including via recombination
with DWV-A, could be of significant ecological and economic importance. Our findings
emphasize that knowledge of pathogen genetic identity and diversity is critical
to understanding drivers of species decline.

text: 'Reciprocal coevolution between host and pathogen is widely seen as a major
driver of evolution and biological innovation. Yet, to date, the underlying genetic
mechanisms and associated trait functions that are unique to rapid coevolutionary
change are generally unknown. We here combined experimental evolution of the bacterial
biocontrol agent Bacillus thuringiensis and its nematode host Caenorhabditis elegans
with large-scale phenotyping, whole genome analysis, and functional genetics to
demonstrate the selective benefit of pathogen virulence and the underlying toxin
genes during the adaptation process. We show that: (i) high virulence was specifically
favoured during pathogen–host coevolution rather than pathogen one-sided adaptation
to a nonchanging host or to an environment without host; (ii) the pathogen genotype
BT-679 with known nematocidal toxin genes and high virulence specifically swept
to fixation in all of the independent replicate populations under coevolution
but only some under one-sided adaptation; (iii) high virulence in the BT-679-dominated
populations correlated with elevated copy numbers of the plasmid containing the
nematocidal toxin genes; (iv) loss of virulence in a toxin-plasmid lacking BT-679
isolate was reconstituted by genetic reintroduction or external addition of the
toxins.We conclude that sustained coevolution is distinct from unidirectional
selection in shaping the pathogen''s genome and life history characteristics.
To our knowledge, this study is the first to characterize the pathogen genes involved
in coevolutionary adaptation in an animal host–pathogen interaction system.'

text: Reproduction within a host and transmission to the next host are crucial for
the virulence and fitness of pathogens. Nevertheless, basic knowledge about such
parameters is often missing from the literature, even for well-studied bacteria,
such as Bacillus thuringiensis, an endospore-forming insect pathogen, which infects
its hosts via the oral route. To characterize bacterial replication success, we
made use of an experimental oral infection system for the red flour beetle Tribolium
castaneum and developed a flow cytometric assay for the quantification of both
spore ingestion by the individual beetle larvae and the resulting spore load after
bacterial replication and resporulation within cadavers. On average, spore numbers
increased 460-fold, showing that Bacillus thuringiensis grows and replicates successfully
in insect cadavers. By inoculating cadaver-derived spores and spores from bacterial
stock cultures into nutrient medium, we next investigated outgrowth characteristics
of vegetative cells and found that cadaver- derived bacteria showed reduced growth
compared to bacteria from the stock cultures. Interestingly, this reduced growth
was a consequence of inhibited spore germination, probably originating from the
host and resulting in reduced host mortality in subsequent infections by cadaver-derived
spores. Nevertheless, we further showed that Bacillus thuringiensis transmission
was possible via larval cannibalism when no other food was offered. These results
contribute to our understanding of the ecology of Bacillus thuringiensis as an
insect pathogen.

text: This paper introduces a theme issue presenting the latest developments in
research on the impacts of sociality on health and fitness. The articles that
follow cover research on societies ranging from insects to humans. Variation in
measures of fitness (i.e. survival and reproduction) has been linked to various
aspects of sociality in humans and animals alike, and variability in individual
health and condition has been recognized as a key mediator of these relationships.
Viewed from a broad evolutionary perspective, the evolutionary transitions from
a solitary lifestyle to group living have resulted in several new health-related
costs and benefits of sociality. Social transmission of parasites within groups
represents a major cost of group living, but some behavioural mechanisms, such
as grooming, have evolved repeatedly to reduce this cost. Group living also has
created novel costs in terms of altered susceptibility to infectious and non-infectious
disease as a result of the unavoidable physiological consequences of social competition
and integration, which are partly alleviated by social buffering in some vertebrates.
Here, we define the relevant aspects of sociality, summarize their health-related
costs and benefits, and discuss possible fitness measures in different study systems.
Given the pervasive effects of social factors on health and fitness, we propose
a synthesis of existing conceptual approaches in disease ecology, ecological immunology
and behavioural neurosciences by adding sociality as a key factor, with the goal
to generate a broader framework for organismal integration of health-related research.

text: 'Entomopathogenic fungi are potent biocontrol agents that are widely used
against insect pests, many of which are social insects. Nevertheless, theoretical
investigations of their particular life history are scarce. We develop a model
that takes into account the main distinguishing features between traditionally
studied diseases and obligate killing pathogens, like the (biocontrol-relevant)
insect-pathogenic fungi Metarhizium and Beauveria. First, obligate killing entomopathogenic
fungi produce new infectious particles (conidiospores) only after host death and
not yet on the living host. Second, the killing rates of entomopathogenic fungi
depend strongly on the initial exposure dosage, thus we explicitly consider the
pathogen load of individual hosts. Further, we make the model applicable not only
to solitary host species, but also to group living species by incorporating social
interactions between hosts, like the collective disease defences of insect societies.
Our results identify the optimal killing rate for the pathogen that minimises
its invasion threshold. Furthermore, we find that the rate of contact between
hosts has an ambivalent effect: dense interaction networks between individuals
are considered to facilitate disease outbreaks because of increased pathogen transmission.
In social insects, this is compensated by their collective disease defences, i.e.,
social immunity. For the type of pathogens considered here, we show that even
without social immunity, high contact rates between live individuals dilute the
pathogen in the host colony and hence can reduce individual pathogen loads below
disease-causing levels.'

text: 'Summary: Declining populations of bee pollinators are a cause of concern,
with major repercussions for biodiversity loss and food security. RNA viruses
associated with honeybees represent a potential threat to other insect pollinators,
but the extent of this threat is poorly understood. This study aims to attain
a detailed understanding of the current and ongoing risk of emerging infectious
disease (EID) transmission between managed and wild pollinator species across
a wide range of RNA viruses. Within a structured large-scale national survey across
26 independent sites, we quantify the prevalence and pathogen loads of multiple
RNA viruses in co-occurring managed honeybee (Apis mellifera) and wild bumblebee
(Bombus spp.) populations. We then construct models that compare virus prevalence
between wild and managed pollinators. Multiple RNA viruses associated with honeybees
are widespread in sympatric wild bumblebee populations. Virus prevalence in honeybees
is a significant predictor of virus prevalence in bumblebees, but we remain cautious
in speculating over the principle direction of pathogen transmission. We demonstrate
species-specific differences in prevalence, indicating significant variation in
disease susceptibility or tolerance. Pathogen loads within individual bumblebees
may be high and in the case of at least one RNA virus, prevalence is higher in
wild bumblebees than in managed honeybee populations. Our findings indicate widespread
transmission of RNA viruses between managed and wild bee pollinators, pointing
to an interconnected network of potential disease pressures within and among pollinator
species. In the context of the biodiversity crisis, our study emphasizes the importance
of targeting a wide range of pathogens and defining host associations when considering
potential drivers of population decline.'

text: To prevent epidemics, insect societies have evolved collective disease defences
that are highly effective at curing exposed individuals and limiting disease transmission
to healthy group members. Grooming is an important sanitary behaviour—either performed
towards oneself (self-grooming) or towards others (allogrooming)—to remove infectious
agents from the body surface of exposed individuals, but at the risk of disease
contraction by the groomer. We use garden ants (Lasius neglectus) and the fungal
pathogen Metarhizium as a model system to study how pathogen presence affects
self-grooming and allogrooming between exposed and healthy individuals. We develop
an epidemiological SIS model to explore how experimentally observed grooming patterns
affect disease spread within the colony, thereby providing a direct link between
the expression and direction of sanitary behaviours, and their effects on colony-level
epidemiology. We find that fungus-exposed ants increase self-grooming, while simultaneously
decreasing allogrooming. This behavioural modulation seems universally adaptive
and is predicted to contain disease spread in a great variety of host–pathogen
systems. In contrast, allogrooming directed towards pathogen-exposed individuals
might both increase and decrease disease risk. Our model reveals that the effect
of allogrooming depends on the balance between pathogen infectiousness and efficiency
of social host defences, which are likely to vary across host–pathogen systems.

text: 'The fitness effects of symbionts on their hosts can be context-dependent,
with usually benign symbionts causing detrimental effects when their hosts are
stressed, or typically parasitic symbionts providing protection towards their
hosts (e.g. against pathogen infection). Here, we studied the novel association
between the invasive garden ant Lasius neglectus and its fungal ectosymbiont Laboulbenia
formicarum for potential costs and benefits. We tested ants with different Laboulbenia
levels for their survival and immunity under resource limitation and exposure
to the obligate killing entomopathogen Metarhizium brunneum. While survival of
L. neglectus workers under starvation was significantly decreased with increasing
Laboulbenia levels, host survival under Metarhizium exposure increased with higher
levels of the ectosymbiont, suggesting a symbiont-mediated anti-pathogen protection,
which seems to be driven mechanistically by both improved sanitary behaviours
and an upregulated immune system. Ants with high Laboulbenia levels showed significantly
longer self-grooming and elevated expression of immune genes relevant for wound
repair and antifungal responses (β-1,3-glucan binding protein, Prophenoloxidase),
compared with ants carrying low Laboulbenia levels. This suggests that the ectosymbiont
Laboulbenia formicarum weakens its ant host by either direct resource exploitation
or the costs of an upregulated behavioural and immunological response, which,
however, provides a prophylactic protection upon later exposure to pathogens. '

text: 'Repeated pathogen exposure is a common threat in colonies of social insects,
posing selection pressures on colony members to respond with improved disease-defense
performance. We here tested whether experience gained by repeated tending of low-level
fungus-exposed (Metarhizium robertsii) larvae may alter the performance of sanitary
brood care in the clonal ant, Platythyrea punctata. We trained ants individually
over nine consecutive trials to either sham-treated or fungus-exposed larvae.
We then compared the larval grooming behavior of naive and trained ants and measured
how effectively they removed infectious fungal conidiospores from the fungus-exposed
larvae. We found that the ants changed the duration of larval grooming in response
to both, larval treatment and their level of experience: (1) sham-treated larvae
received longer grooming than the fungus-exposed larvae and (2) trained ants performed
less self-grooming but longer larval grooming than naive ants, which was true
for both, ants trained to fungus-exposed and also to sham-treated larvae. Ants
that groomed the fungus-exposed larvae for longer periods removed a higher number
of fungal conidiospores from the surface of the fungus-exposed larvae. As experienced
ants performed longer larval grooming, they were more effective in fungal removal,
thus making them better caretakers under pathogen attack of the colony. By studying
this clonal ant, we can thus conclude that even in the absence of genetic variation
between colony members, differences in experience levels of brood care may affect
performance of sanitary brood care in social insects.'

text: "The co-evolution of hosts and pathogens is characterized by continuous adaptations
of both parties. Pathogens of social insects need to adapt towards disease defences
at two levels: 1) individual immunity of each colony member consisting of behavioural
defence strategies as well as humoral and cellular immune responses and 2) social
immunity that is collectively performed by all group members comprising behavioural,
physiological and organisational defence strategies.\r\n\r\nTo disentangle the
selection pressure on pathogens by the collective versus individual level of disease
defence in social insects, we performed an evolution experiment using the Argentine
Ant, Linepithema humile, as a host and a mixture of the general insect pathogenic
fungus Metarhizium spp. (6 strains) as a pathogen. We allowed pathogen evolution
over 10 serial host passages to two different evolution host treatments: (1) only
individual host immunity in a single host treatment, and (2) simultaneously acting
individual and social immunity in a social host treatment, in which an exposed
ant was accompanied by two untreated nestmates.\r\n\r\nBefore starting the pathogen
evolution experiment, the 6 Metarhizium spp. strains were characterised concerning
conidiospore size killing rates in singly and socially reared ants, their competitiveness
under coinfecting conditions and their influence on ant behaviour. We analysed
how the ancestral atrain mixture changed in conidiospere size, killing rate and
strain composition dependent on host treatment (single or social hosts) during
10 passages and found that killing rate and conidiospere size of the pathogen
increased under both evolution regimes, but different depending on host treatment.\r\n\r\nTesting
the evolved strain mixtures that evolved under either the single or social host
treatment under both single and social current rearing conditions in a full factorial
design experiment revealed that the additional collective defences in insect societies
add new selection pressure for their coevolving pathogens that compromise their
ability to adapt to its host at the group level. To our knowledge, this is the
first study directly measuring the influence of social immunity on pathogen evolution."

text: The unprecedented polymorphism in the major histocompatibility complex (MHC)
genes is thought to be maintained by balancing selection from parasites. However,
do parasites also drive divergence at MHC loci between host populations, or do
the effects of balancing selection maintain similarities among populations? We
examined MHC variation in populations of the livebearing fish Poecilia mexicana
and characterized their parasite communities. Poecilia mexicana populations in
the Cueva del Azufre system are locally adapted to darkness and the presence of
toxic hydrogen sulphide, representing highly divergent ecotypes or incipient species.
Parasite communities differed significantly across populations, and populations
with higher parasite loads had higher levels of diversity at class II MHC genes.
However, despite different parasite communities, marked divergence in adaptive
traits and in neutral genetic markers, we found MHC alleles to be remarkably similar
among host populations. Our findings indicate that balancing selection from parasites
maintains immunogenetic diversity of hosts, but this process does not promote
MHC divergence in this system. On the contrary, we suggest that balancing selection
on immunogenetic loci may outweigh divergent selection causing divergence, thereby
hindering host divergence and speciation. Our findings support the hypothesis
that balancing selection maintains MHC similarities among lineages during and
after speciation (trans-species evolution).

text: Immune systems are able to protect the body against secondary infection with
the same parasite. In insect colonies, this protection is not restricted to the
level of the individual organism, but also occurs at the societal level. Here,
we review recent evidence for and insights into the mechanisms underlying individual
and social immunisation in insects. We disentangle general immune-protective effects
from specific immune memory (priming), and examine immunisation in the context
of the lifetime of an individual and that of a colony, and of transgenerational
immunisation that benefits offspring. When appropriate, we discuss parallels with
disease defence strategies in human societies. We propose that recurrent parasitic
threats have shaped the evolution of both the individual immune systems and colony-level
social immunity in insects.

text: Emerging infectious diseases (EIDs) pose a risk to human welfare, both directly
and indirectly, by affecting managed livestock and wildlife that provide valuable
resources and ecosystem services, such as the pollination of crops. Honeybees
(Apis mellifera), the prevailing managed insect crop pollinator, suffer from a
range of emerging and exotic high-impact pathogens, and population maintenance
requires active management by beekeepers to control them. Wild pollinators such
as bumblebees (Bombus spp.) are in global decline, one cause of which may be pathogen
spillover from managed pollinators like honeybees or commercial colonies of bumblebees.
Here we use a combination of infection experiments and landscape-scale field data
to show that honeybee EIDs are indeed widespread infectious agents within the
pollinator assemblage. The prevalence of deformed wing virus (DWV) and the exotic
parasite Nosema ceranae in honeybees and bumblebees is linked; as honeybees have
higher DWV prevalence, and sympatric bumblebees and honeybees are infected by
the same DWV strains, Apis is the likely source of at least one major EID in wild
pollinators. Lessons learned from vertebrates highlight the need for increased
pathogen control in managed bee species to maintain wild pollinators, as declines
in native pollinators may be caused by interspecies pathogen transmission originating
from managed pollinators.

of their hosts. Likewise, host behavioural changes can be a defence mechanism,
counteracting the impact of pathogens on host fitness. We apply harmonic radar

diseases have been proposed to play a prominent role in colony decline, partly
through sub-lethal behavioural manipulation of their hosts. We found that homing
success was significantly reduced in diseased (65.8%) versus healthy foragers
(92.5%). Although lost bees had significantly reduced continuous flight times
and prolonged resting times, other flight characteristics and navigational abilities
showed no significant difference between infected and non-infected bees. Our results
suggest that infected bees express normal flight characteristics but are constrained
in their homing ability, potentially compromising the colony by reducing its resource
inputs, but also counteracting the intra-colony spread of infection. We provide
the first high-resolution analysis of sub-lethal effects of an emerging disease
on insect flight behaviour. The potential causes and the implications for both
host and parasite are discussed.

text: 'Repeated pathogen exposure is a common threat in colonies of social insects,
posing selection pressures on colony members to respond with improved disease-defense
performance. We here tested whether experience gained by repeated tending of low-level
fungus-exposed (Metarhizium robertsii) larvae may alter the performance of sanitary
brood care in the clonal ant, Platythyrea punctata. We trained ants individually
over nine consecutive trials to either sham-treated or fungus-exposed larvae.
We then compared the larval grooming behavior of naive and trained ants and measured
how effectively they removed infectious fungal conidiospores from the fungus-exposed
larvae. We found that the ants changed the duration of larval grooming in response
to both, larval treatment and their level of experience: (1) sham-treated larvae
received longer grooming than the fungus-exposed larvae and (2) trained ants performed
less self-grooming but longer larval grooming than naive ants, which was true
for both, ants trained to fungus-exposed and also to sham-treated larvae. Ants
that groomed the fungus-exposed larvae for longer periods removed a higher number
of fungal conidiospores from the surface of the fungus-exposed larvae. As experienced
ants performed longer larval grooming, they were more effective in fungal removal,
thus making them better caretakers under pathogen attack of the colony. By studying
this clonal ant, we can thus conclude that even in the absence of genetic variation
between colony members, differences in experience levels of brood care may affect
performance of sanitary brood care in social insects.'

text: The fitness effects of symbionts on their hosts can be context-dependent,
with usually benign symbionts causing detrimental effects when their hosts are
stressed, or typically parasitic symbionts providing protection towards their
hosts (e.g. against pathogen infection). Here, we studied the novel association
between the invasive garden ant Lasius neglectus and its fungal ectosymbiont Laboulbenia
formicarum for potential costs and benefits. We tested ants with different Laboulbenia
levels for their survival and immunity under resource limitation and exposure
to the obligate killing entomopathogen Metarhizium brunneum. While survival of
L. neglectus workers under starvation was significantly decreased with increasing
Laboulbenia levels, host survival under Metarhizium exposure increased with higher
levels of the ectosymbiont, suggesting a symbiont-mediated anti-pathogen protection,
which seems to be driven mechanistically by both improved sanitary behaviours
and an upregulated immune system. Ants with high Laboulbenia levels showed significantly
longer self-grooming and elevated expression of immune genes relevant for wound
repair and antifungal responses (β-1,3-glucan binding protein, Prophenoloxidase),
compared with ants carrying low Laboulbenia levels. This suggests that the ectosymbiont
Laboulbenia formicarum weakens its ant host by either direct resource exploitation
or the costs of an upregulated behavioural and immunological response, which,
however, provides a prophylactic protection upon later exposure to pathogens.

text: 'Background: The brood of ants and other social insects is highly susceptible
to pathogens, particularly those that penetrate the soft larval and pupal cuticle.
We here test whether the presence of a pupal cocoon, which occurs in some ant
species but not in others, affects the sanitary brood care and fungal infection
patterns after exposure to the entomopathogenic fungus Metarhizium brunneum. We
use a) a comparative approach analysing four species with either naked or cocooned
pupae and b) a within-species analysis of a single ant species, in which both
pupal types co-exist in the same colony. Results: We found that the presence of
a cocoon did not compromise fungal pathogen detection by the ants and that species
with cocooned pupae increased brood grooming after pathogen exposure. All tested
ant species further removed brood from their nests, which was predominantly expressed
towards larvae and naked pupae treated with the live fungal pathogen. In contrast,
cocooned pupae exposed to live fungus were not removed at higher rates than cocooned
pupae exposed to dead fungus or a sham control. Consistent with this, exposure
to the live fungus caused high numbers of infections and fungal outgrowth in larvae
and naked pupae, but not in cocooned pupae. Moreover, the ants consistently removed
the brood prior to fungal outgrowth, ensuring a clean brood chamber. Conclusion:
Our study suggests that the pupal cocoon has a protective effect against fungal
infection, causing an adaptive change in sanitary behaviours by the ants. It further
demonstrates that brood removal - originally described for honeybees as “hygienic
behaviour” – is a widespread sanitary behaviour in ants, which likely has important
implications on disease dynamics in social insect colonies.'

text: In this thesis I studied various individual and social immune defences employed
by the invasive garden ant Lasius neglectus mostly against entomopathogenic fungi. The
first two chapters of this thesis address the phenomenon of 'social immunisation'.
Social immunisation, that is the immunological protection of group members due
to social contact to a pathogen-exposed nestmate, has been described in various
social insect species against different types of pathogens. However, in the case
of entomopathogenic fungi it has, so far, only been demonstrated that social immunisation
exists at all. Its underlying mechanisms r any other properties were, however,
unknown. In the first chapter of this thesis I identified the mechanistic basis
of social immunisation in L. neglectus against the entomopathogenous fungus Metarhizium.
I could show that nestmates of a pathogen-exposed individual contract low-level
infections due to social interactions. These low-level infections are, however,
non-lethal and cause an active stimulation of the immune system, which protects
the nestmates upon subsequent pathogen encounters. In the second chapter of this
thesis I investigated the specificity and colony level effects of social immunisation.
I demonstrated that the protection conferred by social immunisation is highly
specific, protecting ants only against the same pathogen strain. In addition,
depending on the respective context, social immunisation may even cause fitness
costs. I further showed that social immunisation crucially affects sanitary behaviour
and disease dynamics within ant groups. In the third chapter of this thesis I
studied the effects of the ectosymbiotic fungus Laboulbenia formicarum on its
host L. neglectus. Although Laboulbeniales are the largest order of insect-parasitic
fungi, research concerning host fitness consequence is sparse. I showed that highly
Laboulbenia-infected ants sustain fitness costs under resource limitation, however,
gain fitness benefits when exposed to an entomopathogenus fungus. These effects
are probably cause by a prophylactic upregulation of behavioural as well as physiological
immune defences in highly infected ants.

text: 'Im Rahmen meiner Arbeit mit der kollektiven Krankheitsabwehr in Ameisengesellschaften
interessiert mich vor allem, wie sich die Kolonien als Ganzes gegen Krankheiten
wehren können. Warum ist dieses Thema der Krankheitsdynamik in Gruppen so wichtig?
Ein Vergleich von solitär lebenden Individuen mit Individuen, die in sozialen
Gruppen zusammenleben, zeigt die Kosten und die Vorteile des Gruppenlebens: Einerseits
haben Individuen in sozialen Gruppen aufgrund der hohen Dichte, in der die Tiere
zusammenleben, den hohen Interaktionsraten, die sie miteinander haben, und der
engen Verwandtschaft, die sie verbindet, ein höheres Ansteckungsrisiko. Andererseits
kann die individuelle Krankheitsabwehr durch die kollektive Abwehr in den Gruppen
ergänzt werden.'

text: Selection for disease control is believed to have contributed to shape the
organisation of insect societies — leading to interaction patterns that mitigate
disease transmission risk within colonies, conferring them ‘organisational immunity’.
Recent studies combining epidemiological models with social network analysis have
identified general properties of interaction networks that may hinder propagation
of infection within groups. These can be prophylactic and/or induced upon pathogen
exposure. Here we review empirical evidence for these two types of organisational
immunity in social insects and describe the individual-level behaviours that underlie
it. We highlight areas requiring further investigation, and emphasise the need
for tighter links between theory and empirical research and between individual-level
and collective-level analyses.

text: Pathogens exert a strong selection pressure on organisms to evolve effective
immune defences. In addition to individual immunity, social organisms can act
cooperatively to produce collective defences. In many ant species, queens have
the option to found a colony alone or in groups with other, often unrelated, conspecifics.
These associations are transient, usually lasting only as long as each queen benefits
from the presence of others. In fact, once the first workers emerge, queens fight
to the death for dominance. One potential advantage of co-founding may be that
queens benefit from collective disease defences, such as mutual grooming, that
act against common soil pathogens. We test this hypothesis by exposing single
and co-founding queens to a fungal parasite, in order to assess whether queens
in co-founding associations have improved survival. Surprisingly, co-foundresses
exposed to the entomopathogenic fungus Metarhizium did not engage in cooperative
disease defences, and consequently, we find no direct benefit of multiple queens
on survival. However, an indirect benefit was observed, with parasite-exposed
queens producing more brood when they co-founded, than when they were alone. We
suggest this is due to a trade-off between reproduction and immunity. Additionally,
we report an extraordinary ability of the queens to tolerate an infection for
long periods after parasite exposure. Our study suggests that there are no social
immunity benefits for co-founding ant queens, but that in parasite-rich environments,
the presence of additional queens may nevertheless improve the chances of colony
founding success.

text: 'Background: The brood of ants and other social insects is highly susceptible
to pathogens, particularly those that penetrate the soft larval and pupal cuticle.
We here test whether the presence of a pupal cocoon, which occurs in some ant
species but not in others, affects the sanitary brood care and fungal infection
patterns after exposure to the entomopathogenic fungus Metarhizium brunneum. We
use a) a comparative approach analysing four species with either naked or cocooned
pupae and b) a within-species analysis of a single ant species, in which both
pupal types co-exist in the same colony. Results: We found that the presence of
a cocoon did not compromise fungal pathogen detection by the ants and that species
with cocooned pupae increased brood grooming after pathogen exposure. All tested
ant species further removed brood from their nests, which was predominantly expressed
towards larvae and naked pupae treated with the live fungal pathogen. In contrast,
cocooned pupae exposed to live fungus were not removed at higher rates than cocooned
pupae exposed to dead fungus or a sham control. Consistent with this, exposure
to the live fungus caused high numbers of infections and fungal outgrowth in larvae
and naked pupae, but not in cocooned pupae. Moreover, the ants consistently removed
the brood prior to fungal outgrowth, ensuring a clean brood chamber. Conclusion:
Our study suggests that the pupal cocoon has a protective effect against fungal
infection, causing an adaptive change in sanitary behaviours by the ants. It further
demonstrates that brood removal-originally described for honeybees as "hygienic
behaviour"-is a widespread sanitary behaviour in ants, which likely has important
implications on disease dynamics in social insect colonies.'

text: To fight infectious diseases, host immune defenses are employed at multiple
levels. Sanitary behavior, such as pathogen avoidance and removal, acts as a first
line of defense to prevent infection [1] before activation of the physiological
immune system. Insect societies have evolved a wide range of collective hygiene
measures and intensive health care toward pathogen-exposed group members [2].
One of the most common behaviors is allogrooming, in which nestmates remove infectious
particles from the body surfaces of exposed individuals [3]. Here we show that,
in invasive garden ants, grooming of fungus-exposed brood is effective beyond
the sheer mechanical removal of fungal conidiospores; it also includes chemical
disinfection through the application of poison produced by the ants themselves.
Formic acid is the main active component of the poison. It inhibits fungal growth
of conidiospores remaining on the brood surface after grooming and also those
collected in the mouth of the grooming ant. This dual function is achieved by
uptake of the poison droplet into the mouth through acidopore self-grooming and
subsequent application onto the infectious brood via brood grooming. This extraordinary
behavior extends the current understanding of grooming and the establishment of
social immunity in insect societies.

text: 'Social insects have a very high potential to become invasive pest species.
Here, we explore how their social lifestyle and their interaction with parasites
may contribute to this invasive success. Similar to solitary species, parasite
release followed by the evolution of increased competitive ability can promote
establishment of introduced social insect hosts in their introduced range. Genetic
bottlenecks during introduction of low numbers of founder individuals decrease
the genetic diversity at three levels: the population, the colony and the individual,
with the colony level being specific to social insects. Reduced genetic diversity
can affect both the individual immune system and the collective colony-level disease
defences (social immunity). Still, the dual immune system is likely to make social
insects more robust to parasite attack. Changes in social structure from small,
family-based, territorially aggressive societies in native populations towards
huge networks of cooperating nests (unicoloniality) occur in some invasive social
insects, for example, most invasive ants and some termites. Unicoloniality is
likely to affect disease dynamics in multiple ways. The free exchange of individuals
within the population leads to an increased genetic heterogeneity among individuals
of a single nest, thereby decreasing disease transmission. However, the multitude
of reproductively active queens per colony buffers the effect of individual diseased
queens and their offspring, which may result in a higher level of vertical disease
transmission in unicolonial societies. Lastly, unicoloniality provides a competitive
advantage over native species, allowing them to quickly become the dominant species
in the habitat, which in turn selects for parasite adaptation to this common host
genotype and thus eventually a high parasite pressure. Overall, invasions by insect
societies are characterized by general features applying to all introduced species,
as well as idiosyncrasies that emerge from their social lifestyle. It is important
to study these effects in concert to be able to develop efficient management and
biocontrol strategies. © 2012 British Ecological Society.'

text: 'Background: The outcome of male-male competition can be predicted from the
relative fighting qualities of the opponents, which often depend on their age.
In insects, freshly emerged and still sexually inactive males are morphologically
indistinct from older, sexually active males. These young inactive males may thus
be easy targets for older males if they cannot conceal themselves from their attacks.
The ant Cardiocondyla obscurior is characterised by lethal fighting between wingless
(" ergatoid" ) males. Here, we analyse for how long young males are
defenceless after eclosion, and how early adult males can detect the presence
of rival males.Results: We found that old ergatoid males consistently won fights
against ergatoid males younger than two days. Old males did not differentiate
between different types of unpigmented pupae several days before emergence, but
had more frequent contact to ready-to-eclose pupae of female sexuals and winged
males than of workers and ergatoid males. In rare cases, old ergatoid males displayed
alleviated biting of pigmented ergatoid male pupae shortly before adult eclosion,
as well as copulation attempts to dark pupae of female sexuals and winged males.
Ergatoid male behaviour may be promoted by a closer similarity of the chemical
profile of ready-to-eclose pupae to the profile of adults than that of young pupae
several days prior to emergence.Conclusion: Young ergatoid males of C. obscurior
would benefit greatly by hiding their identity from older, resident males, as
they are highly vulnerable during the first two days of their adult lives. In
contrast to the winged males of the same species, which are able to prevent ergatoid
male attacks by chemical female mimicry, young ergatoids do not seem to be able
to produce a protective chemical profile. Conflicts in male-male competition between
ergatoid males of different age thus seem to be resolved in favour of the older
males. This might represent selection at the colony level rather than the individual
level. © 2012 Cremer et al.; licensee BioMed Central Ltd.'

text: 'Reproductive division of labour is a characteristic trait of social insects.
The dominant reproductive individual, often the queen, uses chemical communication
and/or behaviour to maintain her social status. Queens of many social insects
communicate their fertility status via cuticle-bound substances. As these substances
usually possess a low volatility, their range in queen–worker communication is
potentially limited. Here, we investigate the range and impact of behavioural
and chemical queen signals on workers of the ant Temnothorax longispinosus. We
compared the behaviour and ovary development of workers subjected to three different
treatments: workers with direct chemical and physical contact to the queen, those
solely under the influence of volatile queen substances and those entirely separated
from the queen. In addition to short-ranged queen signals preventing ovary development
in workers, we discovered a novel secondary pathway influencing worker behaviour.
Workers with no physical contact to the queen, but exposed to volatile substances,
started to develop their ovaries, but did not change their behaviour compared
to workers in direct contact to the queen. In contrast, workers in queen-separated
groups showed both increased ovary development and aggressive dominance interactions.
We conclude that T. longispinosus queens influence worker ovary development and
behaviour via two independent signals, both ensuring social harmony within the
colony.'

text: 'Some inflammatory stimuli trigger activation of the NLRP3 inflammasome by
inducing efflux of cellular potassium. Loss of cellular potassium is known to
potently suppress protein synthesis, leading us to test whether the inhibition
of protein synthesis itself serves as an activating signal for the NLRP3 inflammasome.
Murine bone marrow-derived macrophages, either primed by LPS or unprimed, were
exposed to a panel of inhibitors of ribosomal function: ricin, cycloheximide,
puromycin, pactamycin, and anisomycin. Macrophages were also exposed to nigericin,
ATP, monosodium urate (MSU), and poly I:C. Synthesis of pro-IL-ß and release of
IL-1ß from cells in response to these agents was detected by immunoblotting and
ELISA. Release of intracellular potassium was measured by mass spectrometry. Inhibition
of translation by each of the tested translation inhibitors led to processing
of IL-1ß, which was released from cells. Processing and release of IL-1ß was reduced
or absent from cells deficient in NLRP3, ASC, or caspase-1, demonstrating the
role of the NLRP3 inflammasome. Despite the inability of these inhibitors to trigger
efflux of intracellular potassium, the addition of high extracellular potassium
suppressed activation of the NLRP3 inflammasome. MSU and double-stranded RNA,
which are known to activate the NLRP3 inflammasome, also substantially inhibited
protein translation, supporting a close association between inhibition of translation
and inflammasome activation. These data demonstrate that translational inhibition
itself constitutes a heretofore-unrecognized mechanism underlying IL-1ß dependent
inflammatory signaling and that other physical, chemical, or pathogen-associated
agents that impair translation may lead to IL-1ß-dependent inflammation through
activation of the NLRP3 inflammasome. For agents that inhibit translation through
decreased cellular potassium, the application of high extracellular potassium
restores protein translation and suppresses activation of the NLRP inflammasome.
For agents that inhibit translation through mechanisms that do not involve loss
of potassium, high extracellular potassium suppresses IL-1ß processing through
a mechanism that remains undefined.'

text: Dispersal is crucial for gene flow and often determines the long-term stability
of meta-populations, particularly in rare species with specialized life cycles.
Such species are often foci of conservation efforts because they suffer disproportionally
from degradation and fragmentation of their habitat. However, detailed knowledge
of effective gene flow through dispersal is often missing, so that conservation
strategies have to be based on mark-recapture observations that are suspected
to be poor predictors of long-distance dispersal. These constraints have been
especially severe in the study of butterfly populations, where microsatellite
markers have been difficult to develop. We used eight microsatellite markers to
analyse genetic population structure of the Large Blue butterfly Maculinea arion
in Sweden. During recent decades, this species has become an icon of insect conservation
after massive decline throughout Europe and extinction in Britain followed by
reintroduction of a seed population from the Swedish island of Öland. We find
that populations are highly structured genetically, but that gene flow occurs
over distances 15 times longer than the maximum distance recorded from mark-recapture
studies, which can only be explained by maximum dispersal distances at least twice
as large as previously accepted. However, we also find evidence that gaps between
sites with suitable habitat exceeding ∼ 20 km induce genetic erosion that can
be detected from bottleneck analyses. Although further work is needed, our results
suggest that M. arion can maintain fully functional metapopulations when they
consist of optimal habitat patches that are no further apart than ∼10 km.

text: Due to the omnipresent risk of epidemics, insect societies have evolved sophisticated
disease defences at the individual and colony level. An intriguing yet little
understood phenomenon is that social contact to pathogen-exposed individuals reduces
susceptibility of previously naive nestmates to this pathogen. We tested whether
such social immunisation in Lasius ants against the entomopathogenic fungus Metarhizium
anisopliae is based on active upregulation of the immune system of nestmates following
contact to an infectious individual or passive protection via transfer of immune
effectors among group members—that is, active versus passive immunisation. We
found no evidence for involvement of passive immunisation via transfer of antimicrobials
among colony members. Instead, intensive allogrooming behaviour between naive
and pathogen-exposed ants before fungal conidia firmly attached to their cuticle
suggested passage of the pathogen from the exposed individuals to their nestmates.
By tracing fluorescence-labelled conidia we indeed detected frequent pathogen
transfer to the nestmates, where they caused low-level infections as revealed
by growth of small numbers of fungal colony forming units from their dissected
body content. These infections rarely led to death, but instead promoted an enhanced
ability to inhibit fungal growth and an active upregulation of immune genes involved
in antifungal defences (defensin and prophenoloxidase, PPO). Contrarily, there
was no upregulation of the gene cathepsin L, which is associated with antibacterial
and antiviral defences, and we found no increased antibacterial activity of nestmates
of fungus-exposed ants. This indicates that social immunisation after fungal exposure
is specific, similar to recent findings for individual-level immune priming in
invertebrates. Epidemiological modeling further suggests that active social immunisation
is adaptive, as it leads to faster elimination of the disease and lower death
rates than passive immunisation. Interestingly, humans have also utilised the
protective effect of low-level infections to fight smallpox by intentional transfer
of low pathogen doses (“variolation” or “inoculation”).

text: To fight infectious diseases, host immune defences are employed at multiple
levels. Sanitary behaviour, such as pathogen avoidance and removal, acts as a
first line of defence to prevent infection [1] before activation of the physiological
immune system. Insect societies have evolved a wide range of collective hygiene
measures and intensive health care towards pathogen-exposed group members [2].
One of the most common behaviours is allogrooming, in which nestmates remove infectious
particles from the body surfaces of exposed individuals [3]. Here we show that,
in invasive garden ants, grooming of fungus-exposed brood is effective beyond
the sheer mechanical removal of fungal conidiospores as it also includes chemical
disinfection through the application of poison produced by the ants themselves.
Formic acid is the main active component of the poison. It inhibits fungal growth
of conidiospores remaining on the brood surface after grooming and also those
collected in the mouth of the grooming ant. This dual function is achieved by
uptake of the poison droplet into the mouth through acidopore self-grooming and
subsequent application onto the infectious brood via brood grooming. This extraordinary
behaviour extends current understanding of grooming and the establishment of social
immunity in insect societies.

text: 'Background: Fragmentation of terrestrial ecosystems has had detrimental effects
on metapopulations of habitat specialists. Maculinea butterflies have been particularly
affected because of their specialized lifecycles, requiring both specific food-plants
and host-ants. However, the interaction between dispersal, effective population
size, and long-term genetic erosion of these endangered butterflies remains unknown.
Using non-destructive sampling, we investigated the genetic diversity of the last
extant population of M. arion in Denmark, which experienced critically low numbers
in the 1980s. Results: Using nine microsatellite markers, we show that the population
is genetically impoverished compared to nearby populations in Sweden, but less
so than monitoring programs suggested. Ten additional short repeat microsatellites
were used to reconstruct changes in genetic diversity and population structure
over the last 77 years from museum specimens. We also tested amplification efficiency
in such historical samples as a function of repeat length and sample age. Low
population numbers in the 1980s did not affect genetic diversity, but considerable
turnover of alleles has characterized this population throughout the time-span
of our analysis. Conclusions: Our results suggest that M. arion is less sensitive
to genetic erosion via population bottlenecks than previously thought, and that
managing clusters of high quality habitat may be key for long-term conservation.'

text: 'Evolutionary theories of ageing predict that life span increases with decreasing
extrinsic mortality, and life span variation among queens in ant species seems
to corroborate this prediction: queens, which are the only reproductive in a colony,
live much longer than queens in multi-queen colonies. The latter often inhabit
ephemeral nest sites and accordingly are assumed to experience a higher mortality
risk. Yet, all prior studies compared queens from different single- and multi-queen
species. Here, we demonstrate an effect of queen number on longevity and fecundity
within a single, socially plastic species, where queens experience the similar
level of extrinsic mortality. Queens from single- and two-queen colonies had significantly
longer lifespan and higher fecundity than queens living in associations of eight
queens. As queens also differ neither in morphology nor the mode of colony foundation,
our study shows that the social environment itself strongly affects ageing rate.'

text: Context-dependent adjustment of mating tactics can drastically increase the
mating success of behaviourally flexible animals. We used the ant Cardiocondyla
obscurior as a model system to study adaptive adjustment of male mating tactics.
This species shows a male diphenism of wingless fighter males and peaceful winged
males. Whereas the wingless males stay and exclusively mate in the maternal colony,
the mating behaviour of winged males is plastic. They copulate with female sexuals
in their natal nests early in life but later disperse in search for sexuals outside.
In this study, we observed the nest-leaving behaviour of winged males under different
conditions and found that they adaptively adjust the timing of their dispersal
to the availability of mating partners, as well as the presence, and even the
type of competitors in their natal nests. In colonies with virgin female queens
winged males stayed longest when they were the only male in the nest. They left
earlier when mating partners were not available or when other males were present.
In the presence of wingless, locally mating fighter males, winged males dispersed
earlier than in the presence of docile, winged competitors. This suggests that
C. obscurior males are capable of estimating their local breeding chances and
adaptively adjust their dispersal behaviour in both an opportunistic and a risk-sensitive
way, thus showing hitherto unknown behavioural plasticity in social insect males.
