用外源激素和某些化合物处理棉铃虫的滞育蛹 ,结果发现早熟素与蜕皮素一样可终止棉铃虫蛹的滞育 ,使其进入到发育阶段。而保幼激素类似物ZR 5 1 5 ,环腺氨酸 (cAMP)和色氨类化合物 (5 HT)则完全不具有终止棉铃虫滞育的作用。结合早熟素还可终止蚜虫寄生蜂AphidiusmatricariaeHaliday和PraonvolucreHaliday的预蛹滞育的报道 ,建议早熟素应具有终止多种类昆虫滞育的功能 Using exogenous hormones and some compounds to deal with the diapause pupae of cotton bollworm, we found that the precocious pheasants, like ecdysone, can stop the diapause of the cotton bollworm pupa and make it enter the developmental stage. While juvenile hormone analogues ZR 5 1 5, cAMP and 5 HT did not end diapause of cotton bollworm at all. In combination with precolonin, the pre-pupal diapause of Aphidius matricariaeHaliday and PraonvolucreHaliday can also be terminated. It is suggested that precocious hormone should stop the diapause of many species of insects
