It is hypothesize that host and parasite are likely to be related chemically, thereby facilitating the necessary mimicry to permit bypassing the colony odor barrier, and discusses evolutionary trends that may have led to social parasitism, focusing on whether slave-making ants and their host species are expected to engage in a coevolutionary arms race.
Conserved Class of Queen Pheromones Stops Social Insect Workers from Reproducing

The results show that queen pheromones are strikingly conserved across at least three independent origins of eusociality, with wasps, ants, and some bees all appearing to use nonvolatile, saturated hydrocarbons to advertise fecundity and/or suppress worker reproduction.

The results suggest that carpenter ants use a fundamentally different mechanism for nest-mate recognition than previously thought and begs for a reappraisal of the mechanisms underlying recognition systems in social insects.
Nestmate recognition in social insects and the role of hydrocarbons

At the end of the 1990s, the notion that cuticular hydrocarbons act as recognition cues was supported mainly by correlative evidence, but significant progress has been made over the last decade.
Identification of an ant queen pheromone regulating worker sterility

It is suggested that the pheromone has a central role in colony organization and support the hypothesis that worker sterility represents altruistic self-restraint in response to an honest quality signal.

Investigation of native populations of the Argentine ant Linepithema humile revealed a very high turnover, likely to involve strong competition between supercolonies and thus act as a potent selective force maintaining unicoloniality over evolutionary time.
Blending of heritable recognition cues among ant nestmates creates distinct colony gestalt odours but prevents within‐colony nepotism

Results indicate that heritable compounds are suitable for establishing a genetic Gestalt for efficient nestmate recognition, but that recognition cues within colonies are insufficiently distinct to allow nepotistic kin discrimination.
The Evolution of Invasiveness in Garden Ants

- 3 December 2008
The results challenge the notion that supercolonial organization is an inevitable consequence of low genetic variation for chemical recognition cues in small invasive founder populations and infer that low variation and limited volatility in cuticular hydrocarbon profiles already existed in the native range in combination with low dispersal and a highly viscous population structure.
The evolution of queen pheromones in the ant genus Lasius
- L. Holman, R. Lanfear, P. D'ettorre
- BiologyJournal of Evolutionary Biology

It is argued that the sensory ecology of the worker response imposes strong stabilizing selection on queen pheromones relative to other hydrocarbons, and this results highlight how honest signalling could minimize evolutionary conflict over reproduction, promoting the evolution and maintenance of eusociality.
Does she smell like a queen? Chemoreception of a cuticular hydrocarbon signal in the ant Pachycondyla inversa

Using electroanntennography and gas chromatography with electroantennographic detection, it is shown that the antennae of P. inversa workers react to this key compound 3,11-diMeC27, which is correlated with ovarian activity and, because it is detected, is likely to assume the role of a fertility signal reflecting the quality of the sender.
