WebHere we test the hypothesis that brood pheromone modulates the sucrose response threshold of bees. Recently the honeybee proboscis extension response to sucrose has been identified as a ”window” into a bee’s perception of sugar. The sucrose response threshold measured in the first week of adult life, prior to foraging age, predicts forage ... WebBrood Recognition This pheromone is released by developing larvae and pupae. It signals to worker bees that brood continues to develop in the hive, which like QMP, limits the development of worker ovaries. Drone Drone Congregation Areas (DCRs) are used as consistent places, year after year, for drones to gather and mate with queens.
