Are multiple honeybee queen pheromones indicators for a queen-workers arms race?
Honeybees are endowed with pheromones, many of which exhibit caste specific composition, one of which is Dufour’s gland pheromone (QDP). The queen possesses long chain esters that are absent in queenright (QR) workers. However queenless (QL) workers that develop ovaries also express these queen substances. The ability of QL-workers to produce the queen-like compounds suggests that under normal ...
متن کاملQueen pheromones modulate DNA methyltransferase activity in bee and ant workers.
DNA methylation is emerging as an important regulator of polyphenism in the social insects. Research has concentrated on differences in methylation between queens and workers, though we hypothesized that methylation is involved in mediating other flexible phenotypes, including pheromone-dependent changes in worker behaviour and physiology. Here, we find that exposure to queen pheromone affects ...
متن کاملMultiple glandular origins of queen pheromones in the fire ant Solenopsis invicta.
The poison sac of the fire ant Solenopsis invicta is the only identified glandular source of pheromones produced by a functional ant queen. This structure, which contains the poison gland, has previously been shown to be the source of a releaser pheromone that mediates queen recognition and tending by workers. The poison sac has also been demonstrated to be the source of a primer pheromone that...
متن کاملConserved class of queen pheromones stops social insect workers from reproducing.
A major evolutionary transition to eusociality with reproductive division of labor between queens and workers has arisen independently at least 10 times in the ants, bees, and wasps. Pheromones produced by queens are thought to play a key role in regulating this complex social system, but their evolutionary history remains unknown. Here, we identify the first sterility-inducing queen pheromones...
متن کاملConserved queen pheromones in bumblebees: a reply to Amsalem et al.
In a recent study, Amsalem, Orlova & Grozinger (2015) performed experiments with Bombus impatiens bumblebees to test the hypothesis that saturated cuticular hydrocarbons are evolutionarily conserved signals used to regulate reproductive division of labor in many Hymenopteran social insects. They concluded that the cuticular hydrocarbon pentacosane (C25), previously identified as a queen pheromo...
