The production of two different types of pheromones by the larvae, gives a powerful signal to adjust all workers for colony tasks, especially larval care. The complementary effect of these pheromonal components supports also the hypothesis that a special chemical syntax exists in the colony for fine-tuning social regulation.
It also confirms the remarkable and unexpected complexity of honey bee pheromonal communication. Analyzed the data: AM DB. Browse Subject Areas?

Abstract Background In honey bee colony, the brood is able to manipulate and chemically control the workers in order to sustain their own development. Introduction In eusocial insects, the brood is completely dependent on the care provided by the nurses.
