Research Abstract |
Neural re-construction during caste transition in social insects was investigated. We first applied dopamine orally to honeybee workers, confirmed dopamine intake in hemolymph and brain, and demonstrated ovarian development by dopamine. Dopamine receptor drugs caused enhancement or inhibition of behavioral activities. Semi-circular muscles in the common oviduct developed with the ovarian development. Homologous motor neurons innervating the reproductive organ were found between queens and reproductive workers, but their morphologies were different between them, suggesting the transition of restricted organs to a reproductive individual.
