Social living poses challenges for individual fitness because of the increased risk of disease transmission among conspecifics. Despite this challenge, sociality is an evolutionarily successful lifestyle, occurring in the most abundant and diverse group of organisms on earth—the social insects. Two contrasting hypotheses predict the evolutionary consequences of sociality on immune systems. The social group hypothesis posits that sociality leads to stronger individual immune systems because of…

External immunity in ant societies: sociality and colony size do not predict investment in antimicrobials
This work quantifies the strength of antimicrobial secretions among 20 ant species that cover a broad spectrum of ant diversity and colony sizes and finds no correlation between antimicrobial activity and colony size.
Integrative Genomics Reveals the Genetics and Evolution of the Honey Bee’s Social Immune System
The results indicate that genes influencing developmental neurobiology and behavior in solitary insects may have been co-opted to give rise to a novel and adaptive social immune phenotype in honey bees, supporting the hypothesis that social immunity contributes to fitness.
Evidence for reduced immune gene diversity and activity during the evolution of termites
This study characterizes the immune gene repertoire of 18 cockroach and termite species, spanning the spectrum of solitary, subsocial and eusocial lifestyles, and finds that termites appear to have evolved a caste-specific social defense system at the expense of individual immune protection.
microRNAs shape social immunity: a potential target for biological control of the termite Reticulitermes chinensis
The findings demonstrated the important role of miRNAs in shaping social immunity in termite colonies, providing insights necessary to understand the potential mechanisms underlying behavioural and physiological disease defences in insects and hence laying the groundwork for miRNA-based pest control.
Social immunity in honeybees—Density dependence, diet, and body mass trade‐offs
Investigating the effects of group density on social immunity in caged honey bees provided the first experimental evidence that group density affects a social immune response in a eusocial insect and showed that the previously reported trade‐off between immunity and body mass extends to social immunity.
Social immunity in the honey bee: do immune-challenged workers enter enforced or self-imposed exile?
It is found that bees that were wounded or immune-challenged were more likely to leave the hive—resulting in their death—compared to healthy controls, and it is established that the latter are identified for banishment by the chemicals present on their body surface.
The effects of social environment and the metapleural gland on disease resistance in acorn ants
It is shown here that social living plays a crucial role in pathogen resistance and that the MG has an important role inPathogen resistance of individual T. curvispinosus ants, and the MG does not play a strong role in social immunity as previously believed.
Social immunity and chemical communication in the honeybee: immune-challenged bees enter enforced or self-imposed exile
It is suggested that immune-challenged bees altruistically banish themselves, and that workers evict sick individuals (which are identified via olfactory cues), putatively because of (kin) selection to limit the spread of pathogens within colonies.
Bidirectional interactions between host social behaviour and parasites arise through ecological and evolutionary processes
The ways in which host social behaviours evolve in response to parasites are considered, highlighting constraints that arise from the need for hosts to maintain benefits of sociality while minimizing fitness costs of parasites.
Eusociality is linked to caste-specific differences in metabolism, immune system, and somatic maintenance-related processes in an ant species.
It is shown that specific metabolic signatures match specific social roles, and the links between such molecular pathways and aging being found in an increasing number of taxa, confirm and strengthen their potential universality.


Social Immunity
Rapid evolution of immune proteins in social insects.
There is now indication that selection on the amino acid composition of the immune-related genes has been an important part in the fight against pathogens by social insects.
Accelerated evolution of innate immunity proteins in social insects: adaptive evolution or relaxed constraint?
The population genetics of innate immune genes in the honey bee Apis mellifera are studied and strong signs of balancing selection on the pathogen recognition gene pgrp-sa are detected, supporting the hypothesis that some aspect of eusociality renders canonical innate immunity superfluous.
A depauperate immune repertoire precedes evolution of sociality in bees
The immune repertoire of two ecologically and commercially important bumblebee species that diverged approximately 18 million years ago are described, finding that the immune systems of these bumblebees, two species of honeybee, and a solitary leafcutting bee, are strikingly similar.

The aim of this review is to highlight common evolutionary principles acting in disease defence at the level of both individual organisms and societies, thereby linking the fields of physiological and ecological immunology.
The results show considerable variation across colonies in an immune trait important for survival, and point toward a significant trade-off between this trait and colony productivity.

Antimicrobial defences increase with sociality in bees
It is found that increases in group size and genetic relatedness were strongly correlated with increasing antimicrobial strength, suggesting selection by microbial pathogens was critical to the evolution of sociality and required the production of strong, front-line antimicrobial defences.
