compounds present on the cuticle have been shown to act as fertility signals. In addition,
specific queen-characteristic hydrocarbons have been implicated as sterility-inducing queen
signals in ants, wasps and bumblebees. In Corbiculate bees, however, the chemical nature
of queen-characteristic and fertility-linked compounds appears to be more diverse than in
ants and wasps. Moreover, it remains unknown how queen signals evolved across this …
