It has been previously known that the secretions of the male accessory glands of Drosophila melanogaster stimulate female reproductive behaviors such as oviposition. Their transfer to and fates in mated females, however, is only poorly known . We have examined some morphological changes in the female reproductive organs, suggesting relation to reproductive behaviors specifically manifested in mated female. The common oviduct, the uterus and the vagina did not show any morphological changes after mating. In the capsule lumen of the spermatheca, quantity of the secretions discharged from the glandular cells seemed not to be changed after mating. No morphological change in the epithelial cells of this organ was observed. In the ventral receptacle, however, many electron dense particles appeared after mating in the microvilli zone of a layer of the cuboidal epithelial cells. These particles were inferred to be formed by the substances absorbed through the pore canals of the chitinous intima of the ventral receptacle . In the cytoplasm of the cuboidal cells, however, typical features of micropinocytosis such as formation of the coated vesicles were not found.
