Abstract
In order to investigate the action of the juvenile hormone (JH) on honeybee caste differentiation two exocrine glands, Koschewnikow and Dufour glands, were chosen for study. Two combs (I & II) were taken from a single posture of a queen to use for this research. In comb I the larvae were treated wit h a topical application of JH in Acetone, and those from the comb II (contr ol group) received only Acetone. Immediately after the emergence of the wor kers, their glands were dissected and prepared for microscopic measurements . The results showed cell area reduction in the Koschewnikow gland induced by the JH application. The results for the Dufour gland displayed taller ep ithelial cells with the JH application. The difference in glandular respons es to the JH relates to gland function, hormone targets, and individual hom eostasis.
