There was no relation between the developmental fate of the non-chilled pupa transplanted the precritical brain and that of the donor pupa, while the termination of the diapause of the non-chilled pupa transplanted the postcritical brain took place only in the cases in which the diapause of the donor pupa was continuing. The inhibition of the termination of the diapause of the recipient chilled pupa occurred in the cases in which the pupa was transplanted the postcritical brain before the critical period for the activation of the own brain, whereas it did not occur in the cases in which the pupa was transplanted after the critical period of the own. This suggests that the pupal brain of this insect has a something inhibitory factor for the activation of the prothoracic glands after the critical period for the activation in developing pupa., Article, 信州大学理学部紀要 8(1): 81-90(1973)}, pages = {81--90}, title = {The Effect of the Transplantation of the Postcritical Brain of the Pupa upon the Termination of the Pupal Diapause in Samia cynthia pryeri.}, volume = {8}, year = {1973} }
