Abstract
Juvenile hormone, the secretion of the corpus allatum, apparently controls the secretory process of the male accessory glands of the yellow fever mosquito, Aedes aegypti. Topical application of a juvenile hormone mimic induces precocious and enhanced secretion. The treatment with the JH mimic not only increases the potency of males to inseminate more numbers of females, but also stimulates secretion in fully depleted glands of A. aegypti which under normal conditions do not renew the secretory process. Males whose accessory glands are depleted due to multiple matings and later treated with the mimic also inseminate. Cauterization of the corpus allatum complex has prevented the secretory function in the glands.
