玉米螟是我国玉米上的主要害虫,分布广、危害重。玉米螟的优势种及其分布的研究是一项具有重要学术价值和实际意义的基础性工作,它直接影响到玉米螟的检疫、测报、防治和科学研究。六浦幌等（1970）根据形态学研究结果指出,欧洲玉米螟[Ostrinia lubilulis（Hiiber)]仅分布于欧洲、西亚、西北非和北美,而分布于亚洲东部、南部和澳大利亚为害的是亚洲玉米螟[Ostrinia furnacalis（Guenee）]。我国有关昆虫分类学家认为六浦幌所用形态学特征存在着很大的个体变异,不能作为区分种的依据,仍保留我国玉米螟为欧洲玉米螟的观点。为了查清万县地区的玉米螟究属何种,作者等在中国农科院植保所的帮助下,1977～1983年通过形态学鉴定、生殖隔离试验、性诱试验、分布调查等途径,取得了一致的结果,证明万县地区玉米螟的优势种是亚洲玉米螟,而不是欧洲玉米螟。
Corn borer is the main pest on corn in China, which is widely distributed and endangered. The study on the dominant species and distribution of corn borer is a basic work of great academic value and practical significance, which directly affects the maize borer quarantine, reporting, prevention and treatment and scientific research. According to the results of morphological studies, Liurappo et al. (1970) indicated that Ostrinia lubilulis (Hiiber) is only distributed in Europe, West Asia, Northwest Africa and North America, while the Asian corn borer [Ostrinia furnacalis (Guenee)]. The insect taxonomists in our country believe that there are great individual variations in the morphological characteristics used by Liupu Sapporo. They can not be used as the basis for distinguishing species and still retain the view that the Chinese corn borer is the European corn borer. In order to find out what kind of corn borer is in Wanxian area, the authors obtained the results of morphological identification, reproductive isolation test, sexual induction test and distribution survey with the help of Plant Protection Institute of Chinese Academy of Agricultural Sciences from 1977 to 1983 The consistent results show that the dominant species of corn borer in Wanxian is the Asian corn borer, not the European corn borer.
