Abstract. Most species of social insect are characterized by a reproductive division of labor among morphologically specialized individuals. In contrast, there exist many species where all individuals are morphologically identical and dominance relationships determine which individuals mate and/or reproduce. In newly founded multiple-foundress associations of the social wasp Polistes dominulus, foundresses establish dominance hierarchies where the top-ranked (alpha) female monopolizes egg… 
Reproductive Status of the social wasp Polistes versicolor (Hymenoptera, Vespidae)
Factors that indicate the reproductive status of females in colonies of the social wasp Polistes versicolor, including cuticular chemical composition, are evaluated, finding no significant morphological differences between these female groups.
Worker rank, reproductive status and cuticular hydrocarbon signature in the ant, Pachycondyla cf. inversa
It is shown that the composition of cuticular hydrocarbons of egg-l laying workers is quantitatively and qualitatively different from that of non-laying workers and resembles the hydrocarbon blend of the queen but does not completely match it.
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.
Chemical Communication and Reproduction Partitioning in Social Wasps
Social wasps encompass species displaying diverse social organization regarding colony cycle, nest foundation, caste differences (from none to significant dimorphism) and number of reproductive
Hydrocarbon rank signatures correlate with differential oophagy and dominance behaviour in Polistes dominulus foundresses
It is found that chemical differences between eggs of subordinate and dominant foundresses can explain the differential success in oophagy enjoyed by dominant individuals and it is proposed that dominance behaviour is an investigative behaviour as well as a ritualized agonistic behaviour.
Reproductive Status of Females in the Eusocial Wasp Polistes ferreri Saussure (Hymenoptera: Vespidae)
Investigation of factors that indicate the reproductive status in females of Polistes ferreri Saussure found that the queens were among the older females in the colony and were always inseminated, while the age of the workers varied according to the stage of colony development.
Cuticular hydrocarbons as caste-linked cues in Neotropical swarm-founding wasps
The results suggest that queens and workers of Epiponini wasps are chemically different from each other at two levels, qualitatively and quantitatively, or merely quantitatively.


Cuticular hydrocarbons correlated with reproductive status in a queenless ant
It is discussed whether 9-C31 provides honest information about egg–laying ability, enabling ants to recognize the different classes of nest–mates involved in reproductive conflicts, and whether fertility cues could reliably underpin the antagonistic interactions occurring in insect societies.
Dominance hierarchy and reproductive conflicts among subordinates in a monogynous queenless ant
The relative importance of chemical communication and dominance interactions to regulate reproduction is investigated and Alpha, beta, and sterile workers have different signatures of cuticular hydrocarbons, and these may provide honest information which underpins worker policing by low-ranking individuals.
Are variations in cuticular hydrocarbons of queens and workers a reliable signal of fertility in the ant Harpegnathos saltator?
A striking correlation of ovarian activity with CHC variation and its correspondence with the observed recognition behavior exhibited by the workers toward egg-laying nestmates suggests that CHCs serve as a fertility signal in the ant H. saltator, a reliable basis for regulating reproduction.
Dominance relationship in the establishment of reproductive division of labour in a primitively eusocial wasp (Ropalidia marginata)
The mechanisms by which a queen establishes her social status in her colony and those by which she continues to suppress reproduction of her nestmates in the absence of overt physical dominance may be quite different.
Monogyny and regulation of worker mating in the queenless ant Dinoponera quadriceps
Comparison evidence indicates that worker mating is often regulated in monogynous species, while unrestricted mating of young individuals is typical of polygynous species (oviposition is regulated subsequently).
Policing behaviour towards virgin egg layers in a polygynous ponerine ant
The results show that sterile workers discriminate against new egg layers, given that their ovaries are not as developed as those of gamergates, and Olfactory detection of different levels of ovarian activity thus appears possible.
Worker policing limits the number of reproductives in a ponerine ant
This work investigated worker policing in the ponerine ant Harpegnathos saltator in which workers are able to mate and replace the founding queen and appears to function primarily in preventing an excess of reproductive workers.
Effects of social conditions on Juvenile Hormone mediated reproductive development in Bombus terrestris workers
It is found that queenless workers had significantly more developed ovaries and higher rates of release of JH than did queenright workers, confirming and extending previous findings that suggest that bumblebee ovarian development is under JH control.
