摘　　要：秆野螟属(Ostrinia)昆虫全球分布20种,寄主广泛,在农业生产中具有重要的经济意义。由于该属地理分布广泛,形态特征复杂,寄主和生态区重叠严重,秆野螟属系统发育研究还存在很多问题尚未解决。本文综合中国秆野螟属分类概况,对目前应用于秆野螟属系统发育研究的各种性状,包括形态特征、性信息素(生殖隔离)以及分子水平的研究进展作了阐述,并针对秆野螟属研究内容的复杂性及其研究现状,提出了相关对策。The genus Ostrinia （Lepidoptera： Crambidae）, with 20 species and a wide range of host plants in the world, is economically significant in agriculture. Many phylogenetic and taxonomic problems about Ostrinia remain unsolved till now, due to its worldwide distribution, complicated morphology and sympatric properties. Advances in Ostrinia phylogeny were summarized in this paper, including taxonomy of Ostrinia in China and some measures used in its phylogenetic studies, including external morphology, sex pheromone and molecular level. Moreover, some strategies were proposed in this paper in order to make new progress in phylogenetic study on Ostrinia.
