In order to elucidate the induction mechanism of summer diapause in Bombyx mandarina of the Japanese populations, the authors mainly focused on the role of the brain. Brain extirpation, which was performed within 12hr after pupation, caused the prolongation of pupal-adult development, although no delay of development was observed when the surgical operation was carried out 72hr after pupation. The brains derived from Bombyx mori or from non-diapausing Bombyx mandarina of Chinese populations had the potency to restore the development in diapausing pupae of Japanese population. Resumption of pupal-adult development could be induced by injection of prothracicotropic hormone (PTTH) from Bombyx mori or 20-hydroxyecdysone. Restoration of oxygen consumption was also observed by the application of these hormones. The results presented here strongly suggest that summer diapause in the Japanese population of Bombyx mandarina is due to the brains inability to synthesize PTTH.
