摘　　要：对分布于中国的11种秆野螟属(Ostrinia)昆虫雄性外生殖器结构进行了比较分析,秆野螟属昆虫雄性外生殖器由生殖瓣、爪形突、抱器、抱器腹、阳茎组成。秆野螟属昆虫雄性外生殖器形态相似度较高,根据爪形突分裂情况,该11个种分为两个大群,其中亚洲玉米螟、欧洲玉米螟、苍耳螟、豆螟、酒花螟、麻螟、刺菜螟和款冬螟为一个大群,而酸模螟、虎杖螟和克什米尔螟为一大群;在第一大群中,根据爪形突中侧叶与两侧叶长度比分为两个亚群,在第一亚群中,根据抱器腹具刺区与无刺区的长度分为两个亚亚群。The male genitalia of the 11 Ostrinia spp.inhabiting China were anatomized and analyzed systematically,which shows that the Ostrinia spp.were highly similar in the morphological structure of genitalia with valves,uncus,claspers,sacculus and penis.The 11 species were classified into 2 groups according to its trilobed or simple uncus.The trilobed-group was divided into 2 subgroups according to the length of mid lobe.According to the structure of sacculus,the Asian corn borer Ostrinia furnacalis was differentiated from the other 5 species in the 1st sub-group.
