结扎对舌蝇幼虫蛹形成的影响

人们很早就知道，如果在幼虫发育的“关键期”到来之前进行结扎，那么在绿头蝇（Calliphora erythrocephala Meig.）幼虫的大脑后部应用结扎线可以防止后部化蛹。如果在关键期过后进行结扎，则整个幼虫会变暗并形成蛹。
IT has been known for a long time that the application of a ligature posterior to the brain in the larva of the blowfly, Calliphora erythrocephala Meig., prevents the pupation of the posterior part, provided that the ligature is applied before a “critical period” in the development of the larva has been reached1. If the ligature is applied after the critical period has passed then the whole larva darkens and forms a puparium.
