Similar policing rates of eggs laid by virgin and mated honey-bee queens.
Worker-policing is a well-documented mechanism that maintains functional worker sterility in queen-right honey-bee colonies. Unknown, however, is the source of the egg-marking signal that is thought to be produced by the queen and used by policing workers to discriminate between queen- and worker-laid eggs. Here we investigate whether mating is necessary for the queen to produce the egg-marking signal. We compare the removal rate of eggs laid by virgin queens and compare this rate with that of eggs laid by mated queens. Our results show that mating does not affect the acceptability of eggs, suggesting that physiological changes linked to the act of mating do not play a role in the production of the queen's egg-marking signal.
