| 内容記述 | Termination of pupal diapause occurs with activation of brain-prothoracic gland system in Samia cynthia pryeri. It does not occur with 20℃-incubation but occurs with 26℃-incubation. To investigate the cause of failure of development in these pupae with 20℃-incubation, a comparison of the histological change of the lateral B-type neurosecretory cells in pars intercerebralis during 20℃-incubation with that during 26℃-incubation and effect of injection of ecdysone on development of the pupae with 20℃-incubation were observed. Histologically, phloxinophil granules of the lateral B-type neurosecretory cells began to decrease at second day of 20℃-incubation as well as those with 26℃-incubation. From this result, it seems to be suggested that activation of release of prothoracicotropic hormone of brain with 20℃-incubation occurs as well as that with 26℃-incubation. Diapausing pupae developed to imagines with injection of both α-ecdysone and β-ecdysone. From present study, it is probable that failure of development of the pupae to imagines with 20℃-incubation is not resulted from failure of activation of the pupal brain with 20℃-incubation but it is resulted from inoccurrence of secretion of prothoracic glands with 20℃-incubation. | |||||||
