Therefore, I suggest a combined mechanism affecting worker sterility: the queen produces a primer pheromone that directly affects worker physiology culminating in ovary inactivation (queen control). SNMPs are insect-specific membrane proteins initially identified in pheromone-sensitive OSNs of Lepidoptera and are indispensable for a proper detection of pheromones. One possibility is piggyback adaptation. Producing a queen-specific set of compounds in the Hymenoptera is particularly challenging because female larvae are totipotent and can develop either to queen or to worker. A gene responsible for these differences, neofeme4, is overexpressed in queens than in workers [40]. While not pheromones, per se, the major histocompatibility complex (MHC) markers on human cells are known to play a role in human mate selection. Proc Natl Acad Sci USA 2003;100:4486–91. A major primer pheromone category in social insects is that of the queen pheromone, which affects the physiology (mainly the inhibition of reproduction) of either workers or other queens. The role of queen pheromones in social insects: queen control or queen signal? Unfortunately, the honeybee is the only social insect to date for which such in-depth study has been performed. In case of social or migrating insects, this pheromones also maintains the cohesion and social integration of the 11. Therefore, their characterization, or even providing proof of their existence, is more difficult. Physiol Entomol 1990;15:483–8. 1993; 45:787–794. Egg marking in the facultatively queenless ant Gnamptogenys striatula: the source and mechanism. Behav Ecol Sociobiol 1991;29:321–32. Chemoreception of a cuticular hydrocarbon signal in the ant Pachycondyla Inversa. This, coupled with the haplo-diploid sex determination system, created an unusual within-colony relatedness that through kin selection enabled the propagation of social traits in the population. Conserved class of queen pheromones stops social insect workers from reproducing. Finally, several independent studies in ants have shown that cuticular hydrocarbons specifically act as nestmate recognition cues. Although these two mechanisms appear mutually exclusive, they need not necessarily be so. Already a member? Physiol Entomol 2004;29:395–9. Pheromone-mediated gene expression in the honey bee brain. At least three sources of the pheromones have been described including the mandibular glands [64] characterized by hydroxy- and oxo- acids and aromatic compounds, tergal glands [65] characterized by hydrocarbons, and Dufour’s gland [23] characterized by long chain esters. How do you calculate the number of neutrons? Social insects are endowed with exocrine glands that produce a dazzling array of chemicals that serve as pheromones, which play a pivotal role in almost every aspect of their biology. Behav Ecol Sociobiol 2001;51:76–86. pheromone insensitivity, eventually leading to a stalemate in the arms race. queen pheromone; inhibitory pheromone; social insect; honest signal; egg volatile; Reproductive division of labor based on castes is a major transition in the evolution of social insects (1, 2).Regulation of the number of fertile queens requires communication between reproductive and nonreproductive individuals, often through pheromones (3–7).Queens of many social insect species … In addition, many ants possess multiple novel glands that probably evolved after sociality became established. The queen can be clearly detected because of the presence of retinue workers around her that feed and groom her extensively [2], [3]; Figure 1]. An even more intriguing point is that perception of the queen pheromone inhibits the production of this very same pheromone in the perceiving individual. [Role of trace pheromones in the regulation of sex ratio in Trissolcus grandis (Hymenoptera, Scelionidae)]. Birch MC, editor. Himuro C, Yokoi T, Matsuura K. Queen-specific volatile in a higher termite Nasutitermes takasagoensis (Isoptera: Termitidae). In the honeybee, it was shown, both by behavioral observations and the use of radiolabeled pheromone, that the retinue workers acquire the queen pheromone by constantly licking her and assuming the role of a messenger bee to transfer pheromone bouts to neighboring workers [4], [13].

Under queenless conditions, however, gyne production is immediately initiated. Proc R Soc B: Biol Sci 1999;266:1323–7. The handicap principle: a missing piece of Darwin’s puzzle.
