摘　　要：以水稻重要害虫稻纵卷叶螟（Ｃｎａｐｈａｌｏｃｒｏｃｉｓ　ｍｅｄｉｎａｌｉｓ Ｇｕｅｎｅｅ）和其主要的寄生性天敌纵卷叶螟绒茧蜂（Ａｐａｎｔｅｌｅｓ　 ｃｙｐｒｉｓ Ｎｉｘｏｎ）为研究对象，重点探讨寄生蜂在寄生过程中对寄主主要器官的发育所造成的影响．结果发现被寄生的稻纵卷叶螟幼虫的脑发育迟缓，有萎缩现象；气管组织不甚发达，分支层次明显减少；精巢和卵巢均不能正常发育．Cnaphalocrocis medinalis Guene and Apanteles cypris Nixon were used as a model system to investigate the effects of parasitization of parasitic wasps on the development of inner organs of hosts. After the larva of C. medinalis Guenee was parasitized by A cypris Nixon, the development of its brain and trachea was delayed, its ovaries or testis failed to develop into maturity.
