Regulation of larval-larval molting and metamorphosis in the tobacco hornworm, Manduca sexta : roles of juvenile hormone, ecdysteroid and the brain /

In Manduca sexta, larval-larval molting of the IVth instar ensues in response to a large pulse of ecdysteroid. Ecdysone release by the prothoracic glands (PG), in turn, is stimulated by prothoracicotropic hormone (PTTH) from the brain. I show that juvenile hormone (JH) is necessary and its titer n...
