Chemical messengers are the primary mode of intracolony communication in the majority of social insect species. Chemically transmitted information plays a major role in nestmate recognition and kin recognition. Physical and behavioral castes often differ in chemical signature, and queen effects can be significant regulators of behavior and reproduction. Chemical messengers themselves differ in molecular structure, and the effects on behavior and other variables can differ as a consequence of… 

Differential Sharing of Chemical Cues by Social Parasites Versus Social Mutualists in a Three-Species Symbiosis

TLDR
There is a fundamental difference in how social mutualists and social parasites use chemicals to integrate themselves into colonies, according to which the parasite obtains chemical cues from both of the two parabiotic host ant species.

Formica francoeuri responds to pheromones and defensive chemical cues of social bees

TLDR
A series of experiments are performed to examine how ant foragers respond to bee pheromones, venom and sting glands in the context of foraging to identify previously cryptic interactions and provide new insights into the hidden mechanisms governing foraging decisions.

Vibrational Behavior in Termites (Isoptera)

TLDR
This chapter reviews the literature on vibrational communication in termites and discusses the outstanding fact that termites construct the substrate, i.e., the nest, mound, and galleries they live in and communicate through, by themselves.

Communication and Social Regulation in Termites

TLDR
This chapter reviews the recent literature on the different components that make up termite communication and social regulation systems by tracing termite evolution and examining the role played by different factors, such as sex and caste, and different behaviors, including those related to defense, nestmate recognition, egg and brood care, foraging, and nest building.

Dear Enemy Phenomenon in the Ant Ectatomma brunneum (Formicidae: Ectatomminae): Chemical Signals Mediate Intraspecific Agressive Interactions

TLDR
The results allow us to confirm the hypothesis that the DEP occurs in E. brunneum and show there are significant differences in CHCs profiles, especially between colonies nested at relatively greater distances, and it is likely that differences in content of some branched alkanes are the most important to establish differences and, therefore, the levels of aggression during the interactions.

Intraspecific variation of cuticular hydrocarbons in the eusocial wasp Polybia sericea (Hymenoptera: Vespidae)

TLDR
It was possible to distinguish the females according to degree of ovarian development, relative age and different body parts in the three analyzed populations; therefore, both the cuticular chemical profile of colony members and compounds found in nest material can be used as complementary tools to assess population differences.

Chemical Variation among Castes, Female Life Stages and Populations of the Facultative Eusocial Sweat Bee Halictus rubicundus (Hymenoptera: Halictidae)

TLDR
This study compared the chemical profiles of social and solitary populations from both continents and tested whether (i) population or social level affect chemical dissimilarity and (ii) caste-specific patterns reflect a conserved queen signal, finding common compounds overproduced in queens compared to workers in both populations, indicating a potential conservedQueen signal.

Intraspecific Cuticular Chemical Profile Variation in the Social Wasp Mischocyttarus consimilis (Hymenoptera, Vespidae)

TLDR
The hypothesis that environmental factors are decisive to compose the cuticular chemical profiles of colonies of these social wasps and that there are differences regarding the geographic distribution among colonies is refuted and it is inferred that in this species neither exogenous nor genetic factors stand out to differentiate the chemical signature of their colonies.

Queen Pheromone and Monopoly of Reproduction by the Queen in the Social Wasp Ropalidia Marginata

TLDR
The mechanism of maintenance of eusociality through pheromonal queen signalling by the Dufour’s gland compounds is elucidated, thereby advocating the honesty of the queen pheromone.

Deciphering the Chemical Basis of Nestmate Recognition

TLDR
This study contributes to the understanding of the chemical basis of nestmate recognition by showing that, similar to spoken language, the chemical language of social insects contains “synonyms,” chemicals that differ in structure, but not meaning.

Food resources, chemical signaling, and nest mate recognition in the ant Formica aquilonia

TLDR
It was found that both isolation per se and diet composition influenced the cuticular chemical profiles in workers of Formica aquilonia, and the level of aggression increased when both the proportions of dietary ingredients and the availability of food were altered, suggesting that increased aggression was mediated by changes in the chemical profile and that environmental cues can mediate recognition between colonies.

Nestmate and Task Cues are Influenced and Encoded Differently within Ant Cuticular Hydrocarbon Profiles

TLDR
It is shown that the other major part of the CHC profile with n-alkane components is influenced strongly by the task a worker performs (foraging vs nonforaging) and is independent of the nestmate signal.

Mixed messages: fertility signaling interferes with nestmate recognition in the monogynous ant Camponotus floridanus

TLDR
This study investigated how information about fertility and colony membership is integrated in the ant Camponotus floridanus and suggested that ants respond to this information in the cuticular hydrocarbon profile: individuals with strong fertility signals are accepted regardless of their colony membership, but individuals without strongertility signals are tolerated only if their cuticular Hydrocarbon profile matches that of colony members.

Cooperation, Conflict, and the Evolution of Queen Pheromones

TLDR
Overall, these studies suggest that queen-worker pheromone communication is a multi-component, labile dialog between the castes, rather than a simple, fixed signal-response system.

How an Ant Manages to Display Individual and Colonial Signals by Using the Same Channel

TLDR
This work identified and selected 11 cuticular hydrocarbons that permitted us to discriminate ovarian development classes and that might function as a fertility signal, which suggests that the two signals (the individual signal of fertility and the common signal of colony identity) can be conveyed by the same compounds.

Chemical Signals in the Stingless Bee, Frieseomelitta varia, Indicate Caste, Gender, Age, and Reproductive Status

TLDR
It is discussed the possibility that these compounds signal a queen’s presence to the colony, thereby initiating all vital worker-queen interactions, and potential chemical variation among castes, gender, age, and reproductive status is investigated.

Are queen ants inhibited by their own pheromone? Regulation of productivity via negative feedback

TLDR
It is suggested that 3-MeC31 is used by ants of both castes to adjust their fecundity to the amount of developing brood and the presence of other reproductives, suggesting that queen pheromones have a multifaceted role in colony organization.
