| Abstract: | Summary Juvenile hormone (JH) hydrolytic activity was determined in different tissues of day-4 last instar larva ofGalleria mellonella. Midgut, gonad, imaginal wing discs and fat body contain higher JH hydrolytic activity than hemolymph, while silk gland and body wall have lower activity. JH esterase activity in imaginal wing discs exhibits a pattern of age-related changes different from that of the hemolymph.We acknowledge the support of this research by the National Institutes of Health (GM 22429) and the Johnson Wax Foundation.
