| 摘 要： | 脑摘除试验表明: 棉铃虫蛹的初期发育（化蛹后12 h 内）受脑的控制；化蛹12 h后的滞育蛹发育与脑无关。注射活性脑的匀浆液可阻止部分注定滞育的预蛹和化蛹后1～2天的蛹进入滞育状态，说明滞育的个体很有可能从预蛹期开始其脑的活性就已降低。

| Abstract: | It was confirmed that the pupae of Helicoverpa armigera needed brain in the early development stage by the experiment of brain excision. The development of diapause pupae did not need brain in the mid or later development stage. The pupal diapause in H. armigera could be terminated with the injection of active brain, and it was suggested that the activation of brain in diapause-destined H. armigera had descended since prepupal stages. The role of brain in diapause in H. armigera was discussed based on these results. |
