Control of Endocrine Gland Activity
The existence of a brain factor involved in the control of molting was discovered by Kopec (1922) in the gypsy moth Lymantria dispar, and demonstrated by Wigglesworth (1940) in the blood-sucking bug Rhodnius prolixus. Its role in activating the molting gland was shown by Williams (1946, 1947) in the great saturniid Platysamia cecropia,by Possompès (1953) in the blowfly Calliphora erythrocephala,and subsequently in various species. In vitro, moreover, molting glands have been shown to be stimulated by the brain (Agui, 1975).
