摘要
The larval pheromone (E)-beta-ocimene (EBO) inhibits worker ovary development and accelerates the behavioral transition from nursing to foraging in the honey bee, Apis mellifera. Because EBO diffuses throughout the hive, it has been hypothesized that honey bee workers can use it to indirectly assess brood abundance. Here, we evaluate this hypothesis by testing whether EBO plays a role in the regulation of worker foraging activity. We exposed paired colonies to a pulse of either synthetic beta-ocimene or paraffin oil control and recorded the subsequent number of pollen and non-pollen foragers returning to the colony. Exposure to synthetic beta-ocimene moderately but significantly increased overall foraging activity, but not pollen foraging. For pollen foraging, the effect of pheromone treatment was the greatest directly after pheromone exposure.
