Resumo:  Background: In honey bee colony, the brood is able to manipulate and chemically control the workers in order to sustaintheir own development. A brood ester pheromone produced primarily by old larvae (4 and 5 days old larvae) was firstidentified as acting as a contact pheromone with specific effects on nurses in the colony. More recently a new volatile broodpheromone has been identified: E-b-ocimene, which partially inhibits ovary development in workers.Methodology and Principal Finding: Our analysis of E-b-ocimene production revealed that young brood (newly hatched to3 days old) produce the highest quantity of E-b-ocimene relative to their body weight. By testing the potential action of thismolecule as a non-specific larval signal, due to its high volatility in the colony, we demonstrated that in the presence of E-bocimenenest workers start to forage earlier in life, as seen in the presence of real brood.Conclusions/Significance: In this way, young larvae are able to assign precedence to the task of foraging by workers inorder to increase food stores for their own development. Thus, in the complexity of honey bee chemical communication, Eb-ocimene, a pheromone of young larvae, provides the brood with the means to express their nutritional needs to theworkers.
