摘　　要：用透射电镜技术研究了棉铃虫 4龄幼虫在蜕皮过程中表皮层及皮细胞的变化 .同时用含蜕皮激素类杀虫剂RH-5 992的饲料饲喂 4龄幼虫 ,导致其产生早熟、异常的致死蜕皮 ,在超微结构水平比较了正常蜕皮与 RH-5 992对皮细胞和新表皮形成的影响 .Cuticle structure and moulting process of cotton bollworn, Helicoverpa armigera (Lepidoptera) were studied by transmission electron microscopy. At the same time, forced feeding of RH-5992 (tebufenozide), a nonsteroidal ecdysone agonist to newly moulted fourth instar larvae initiated a precocious, incomplete moult. The ultrastructural changes of cuticle and epidermis on the Helicoverpa armigera induced by RH-5992 were studied, which compared with normal ecdysis.
