Worker-worker inhibition of honey bee behavioural development independent of queen and brood

摘要

Foragers inhibit the behavioural development of young adult worker honey bees, delaying the age at onset of foraging. But the similar effect caused by pheromones produced by both the queen and brood raised the possibility that some of the previously attributed forager effects might be due to queen, brood, or both. Here we studied whether physical contacts between young bees and old foragers can inhibit behavioural development while controlling for queen and brood effects. Results demonstrated that foragers inhibit the behavioural development of young adult worker bees independent of the queen and brood, via a mechanism that requires physical contact.
