The ability of social insects to discriminate against non-nestmates is vital for maintaining colony integrity, and in most social insect species, individuals act aggressively towards non-nestmates that intrude into their nest. Our experimental field data revealed that intra-colony aggression in the primitive bulldog ant Myrmecia nigriceps is negligible; our series of bioassays revealed no significant difference in the occurrence of aggression in trials involving workers from the same, a close… 

Absence of aggression but not nestmate recognition in an Australian population of the Argentine ant Linepithema humile

It is found that non-nestmates at seaport sites (where populations may derive from multiple introductions) antennate each other with greater frequency than their counterparts from non-seaport Sites, suggesting that the Victorian population of L. humile may comprise multiple independent introductions.

Socially peaceful: foragers of the eusocial bee Lasioglossum malachurum are not aggressive against non-nestmates in circle-tube arenas

The results and comparisons with other bee species suggest that studying worker interactions may be not enough to predict the social organisation in bees, and is in agreement with recent studies showing that L. malachurum colonies may have imperfect nestmate recognition and often include a mixture of related and unrelated workers.

High levels of tolerance between nestmates and non-nestmates in the primitively eusocial sweat bee Halictus scabiosae (Rossi) in Turkey (Hymenoptera: Halictidae)

The hypothesis that reduced intra-colony relatedness, resulting from multiple foundresses and/or drifting among conspecific colonies of eusocial sweat bees, is correlated with high levels of tolerance among nestmates is supported.

Specific recognition of reproductive parasite workers by nest-entrance guards in the bumble bee Bombus terrestris

Chemical analysis revealed that the cuticular chemical profiles of workers encode information about both their colony membership and their current fertility, therefore providing potential recognition cues for a suitable adjustment of the guards’ defensive decisions, and provides a first piece of empirical evidence supporting the hypothesis that an adapted defensive strategy against worker reproductive parasitism exists in B. terrestris colonies.

Colony structure, population structure, and sharing of foraging trees in the ant Myrmecia nigriceps (Hymenoptera: Formicidae)

A significant correlation between tree sharing and geographical distance between nests is revealed and the colony structure of M. nigriceps is investigated, which is found to be monodomous and to have no correlation between internest relatedness and tree sharing.

Aggression in imported fi re ants : an explanation for shifts in their spatial distributions in Southern United States ?

1. The imported fire ants, Solenopsis invicta Buren (red), S. richteri Forel (black), and their hybrids ( S. invicta × S. richteri ) are sympatric congeners with overlapping but shifting spatial

The interplay between genetic and environmental effects on colony insularity in the clonal invasive little fire ant Wasmannia auropunctata

It is proposed that in the field the ants’ diet breadth is broad and consequently the incorporation of diet-borne substances is insufficient to mask the genetically determined cues, thus altering the genetically based cues to the point of alienation in the laboratory.

Confirmation Bias in Studies of Nestmate Recognition: A Cautionary Note for Research into the Behaviour of Animals

A meta-analysis, using studies on nestmate recognition in ants, to compare the outcomes of studies that were conducted blind with those that were not, found that the effect size between nestmate and non-nestmate treatment means is significantly lower in experiments conducted blind than those in which colony identity is known.


The identification of all these functions allows biologists to use cuticular hydrocarbons as tools to conduct eco-ethological studies, and it is possible to use hydrocarbon composition as taxonomic character to identify cryptic species which are morphologically close.



Nest- and colony-mate recognition in polydomous colonies of meat ants (Iridomyrmex purpureus)

Chemical analysis of the cuticular hydrocarbons of workers using a novel comprehensive two-dimensional gas chromatography technique that increases the number of quantifiable compounds revealed both colony- and nest-specific patterns, indicating an incomplete transfer of colony odor between the nests of polydomous meat ant colonies.

Geographic Affinity, Cuticular Hydrocarbons and Colony Recognition in the Australian Meat Ant Iridomyrmex purpureus

It is demonstrated that recognition between conspecific nonnestmates is mediated by these chemicals, however, other cues may also be important since ants responded more aggressively in bioassays using chilled workers than those using only cuticular hydrocarbons.

Social organization in some primitive Australian ants. I.Nothomyrmecia macrops Clark

Levels of inactivity higher than previously observed in ants are confirmed, supporting the hypothesis that Nothomyrmecia is primitively eusocial, and of special significance in myrmecology.

Chemical mimicry of the ant Oecophylla smaragdina by the myrmecophilous spider Cosmophasis bitaeniata: Is it colony-specific?

Investigation of the cuticular hydrocarbon profiles of the salticid spider Cosmophasis bitaeniata and the major workers of the ant colonies revealed that the spiders can distinguish between nestmate and non-nestmate major workers and are less inclined to escape when confined with ants that are nestmates.

Intranest relatedness and nestmate recognition in the meadow ant Formica pratensis (R.)

Positive regression between intranest relatedness of recipient colonies and aggression in the multiple analysis supports earlier results that nestmate recognition is genetically influenced in F. pratensis and indicates that foreign label rejection most likely explains the data.

The kin recognition system of carpenter ants (Camponotus spp.)

A hierarchy of importance of cue sources in determining nestmate discrimination in small Camponotus colonies is proposed: Queen discriminators > worker discriminators>environmental cues.

The kin recognition system of carpenter ants (Camponotus spp.)

The presence of a fully functional queen continues to prevent recognition of unfamiliar kin in larger colonies, but worker cues can become more important when the queen is ineffective, as well as suggesting the involvement of a foreignlabel rejection mechanism.

Cuticular hydrocarbons mediate discrimination of reproductives and nonreproductives in the ant Myrmecia gulosa

It is suggested that cuticular hydrocarbons function as pheromones allowing for recognition of the queen as well as egg-laying workers.

The contributions of kinship and conditioning to nest recognition and colony member recognition in a primitively eusocial bee, Lasioglossum zephyrum (Hymenoptera: Halictidae)

Summary1.In the primitively social halictine bee, Lasioglossum zephyrum, colony unity is maintained through an interplay of both nest recognition and nest mate recognition, using odor cues.2.Nests

Intraspecific aggression in the primitive ant genusMyrmecia

Newly eclosed callow workers of the primitive ant genusMyrmecia were not attacked by workers from different conspecific colonies and this finding contradicts the much quoted anedotal report of Haskins andHaskins (1950).
