Colony defense is a necessary but dangerous task for social insects, and nest defensive behaviors often lead to a premature death of the actor. As an extreme form of colony defense, self-sacrificial behaviors have evolved by kin selection in various social insects. Most self-sacrificial defensive mechanisms occur in response to an acute threat to the colony, but some behaviors are preemptive actions that avert harm to the colony. Self-sacrifice has also been observed as a form of preemptive… 

Appetite for self-destruction: suicidal biting as a nest defense strategy in Trigona stingless bees

The results indicate that suicidal biting may be a widespread defense strategy in stingless bees, but it is not universal and has both parallels and differences with other self-sacrificial worker insects, such as the honey bee.

Managing the risks and rewards of death in eusocial insects

The causes of death, the sensory detection of death and corpse management strategies of social insects are summarized and insights into the evolution of behavioural response to the dead are provided and the ecological relevance of corpse management are provided.

Insect societies fight back: the evolution of defensive traits against social parasites

How social insects try to interrupt this sequence of events by avoiding parasite contact by choosing to nest in parasite-free locales or evade attacks by adapting their colony structure is reviewed.

Exaggeration and cooption of innate immunity for social defense

It is discovered that, in the social aphid Nipponaphis monzeni, molecular and cellular immune components of soldier individuals are extremely up-regulated and massively excreted via “body eruption” upon gall breakage, and the “hyperclotting” body fluid repairs the damaged gall for colony defense, which uncovers unexpected molecular, cellular, and evolutionary commonalities across individual immunity and social immunity.

Soldiers with large weapons behave aggressively against predators: correlated morphological and behavioral defensive traits in a eusocial aphid

It is experimentally showed that in midsummer soldiers behave more aggressively in response to artificial stimuli mimicking contact with a predator than they do in early summer, and this variation correlated with the phenological variation of defensive morphology in soldier aphids.

Social apoptosis in honey bee superorganisms

It is shown that immature workers of the mite’s original host, A. cerana, are more susceptible to V. destructor infestations than those of its new host, thereby enabling more efficient social immunity and contributing to colony survival, and offering empirical support to theoretical arguments about the adaptive value of worker suicide in social insects.

The Evolutionary Puzzle of Suicide

The altruistic suicide hypothesis posits that the presence of low reproductive potential and burdensomeness toward kin can increase the inclusive fitness payoff of self-removal, and the bargaining hypothesis assumes that suicide attempts could function as an honest signal of need.

Queens stay, workers leave: caste-specific responses to fatal infections in an ant

Queens and workers of the ant Temnothorax crassispinus differ in their reaction to an infection risk and a reduced life expectancy; workers isolate themselves to prevent contagion inside the colony, whereas queens stay in the nest.

The Inclusive Behavioral Immune System

It is suggested that sickness behavior has evolved because it reduces the direct and indirect contact between an infected host and its healthy kin – improving inclusive fitness, and the term is broadened to the inclusive behavioral immune system.

Adaptive suicide: is a kin-selected driver of fatal behaviours likely?

A review finds that the most persuasive evidence for selection of adaptive suicide comes from bacteria, and the potential for the evolution of adaptive suicidal behaviour in hosts is considered to apply to cases of infection by pathogens.

Preemptive Defensive Self‐Sacrifice by Ant Workers

The first example of preemptive self‐sacrifice in nest defense is described in the Brazilian ant Forelius pusillus, where one to eight workers finish the job from the outside and, in doing so, sacrifice their lives.

Altruistic self‐removal of health‐compromised honey bee workers from their hive

The combined theoretical and empirical support for altruistic self‐removal suggests that it may be another important kin‐selected behaviour and a potentially widespread mechanism of social immunity.

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.

Adaptive suicidal behaviour in pea aphids

Pea aphid parasitized by the braconid wasp Aphidius ervi, exhibit apparent suicidal behaviour in response to both aphid alarm pheromone and approaching coccinellid (ladybird beetle) predators, believed to be the first convincing evidence in support of the host suicide hypothesis.

Sting autotomy, a defensive mechanism in certain social Hymenoptera

The acquisition of lancet barbs represents a case of convergent evolution among bees, wasps and ants in the order Hymenoptera and is applied in colony defense and not as an offensive mechanism.

Self-organized defensive behavior in honeybees.

The experimental results support a model of defensive behavior of honeybees based on a self-organizing mechanism, and helps to explain several of the characteristic features of the honeybee defensive response.

Caste and ecology in the social insects.

In this pathbreaking and far-reaching work George Oster and Edward Wilson provide the first fully developed theory of caste evolution among the social insects and construct a series of mathematical models to characterize the agents of natural selection that promote particular caste systems.

Manipulation of host behavior by parasitic insects and insect parasites.

This work focuses on recent advances in the study of behavioral manipulation via modulation of the host central nervous system, and describes how a worm may influence the nervous system of its cricket host and manipulate the cricket into committing suicide by jumping into water.
