Are variations in cuticular hydrocarbons of queens and workers a reliable signal of fertility in the ant Harpegnathos saltator?
TLDR
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.

Colony dispersal and the evolution of queen morphology in social Hymenoptera.
TLDR
This work focuses on the characteristics of fission in the phylogenetically primitive ants Ponerinae in which both ergatoid queens and gamergates occur. Expand
Cuticular hydrocarbons correlated with reproductive status in a queenless ant
TLDR
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. Expand
Sex, age and ovarian activity affect cuticular hydrocarbons in Diacamma ceylonense, a queenless ant.
TLDR
Variations in cuticular profile are a reliable reflection of ovarian activity, and could be used by ants as a fertility signal, and are discussed in the context of physiological models of the relation between ovarian activity and the synthesis of cuticular hydrocarbons. Expand
Cuticular hydrocarbons mediate discrimination of reproductives and nonreproductives in the ant Myrmecia gulosa
TLDR
It is suggested that cuticular hydrocarbons function as pheromones allowing for recognition of the queen as well as egg-laying workers. Expand
Dominance hierarchy and reproductive conflicts among subordinates in a monogynous queenless ant
TLDR
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. Expand
Convergent evolution of wingless reproductives across all subfamilies of ants, and sporadic loss of winged queens (Hymenoptera: Formicidae)
TLDR
Wingless reproductives (ergatoid queens, short-winged queens, and gamergates) evolved independently in more than 50 genera belonging to 16 subfamilies because there is tremendous heterogeneity in morphological characteristics as well as selective contexts. Expand
Solid-Phase Microextraction and Cuticular Hydrocarbon Differences Related to Reproductive Activity in Queenless Ant Dinoponera quadriceps
TLDR
It is demonstrated that the alpha ant (virgin or mated) always had higher levels of 9-hentriacontene than her sterile nestmates, and this difference appears related to ovarian activity and may function as a signal of the alpha's dominance status. Expand
Monogyny and regulation of worker mating in the queenless ant Dinoponera quadriceps
TLDR
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). Expand
