中文摘要： 膝芒寄蝇族雌成虫产微型卵，被寄主幼虫连同寄主植物叶片取食后，孵化幼虫寄生于玉米螟、草地螟、粘虫、棉铃虫、松毛虫、舞毒蛾、蚕蛾、粉蝶、蛱蝶、金龟子、叶蜂、大蚊等4目32科昆虫体内，是大多数农、牧、林、果害虫的重要天敌。中国已记录49属139种。本项目调查中国产膝芒寄蝇族资源本底；分类学、生物地理与分子系统学相结合研究方法，分类鉴定中国产各属种类，界定、构建属级阶元为基础的物种多样性编目和分布数据库；记述新分类阶元；订正既知属种；研究各属群寄蝇-寄主植物-植食性蛾类幼虫协同进化，鉴定寄主植物种类、检查寄生部位；光镜、电镜解析我国本族寄蝇卵、幼虫、蛹的形态结构；测定COI和28SrRNA等基因组成数据，利用MEGA4等软件建立分子系统树；综合分析推断本族属间、属群间分类系统和演化关系；解释其分布格局；为研究本族物种起源演化和生物控制鳞翅目等害虫提供基础理论依据和解决对策。

英文摘要： The Goniini is one of the most species-rich tribes of subfamily Exoristinae (Diptera, Tachinidae) of tachinid flies. Goniini producing microtype eggs in females and is recognized as monophyletic only on the basis of internal structures microtype eggs in which ova are ingested by hosts as they feed and hatch in the gut, and the emerging first-instar larvae burrow into the hemocoel. Goniini are parasitic on the larvae of 32 families of 4 orders of insects, Lepidoptera: Arctiidae, Bombycidae, Danaidae, Geometridae, Gracillariidae, Hesperiidae,Lasiocampidae, Limacodidae, Lycaenidae, Lymantriidae, Noctuidae, Notodontidae, Nymphalidae, Papilionidae, Pieridae, Psychidae, Pyralidae, Saturniidae, Satyridae, Tortricidae, Yponomeutidae, Zygaenidae; Coleoptera: Scarabaeidae; Hymenoptera: Tenthredinidae; Diptera: Tipulidae etc. As parasitoids, Goniini are important natural enemies (particularly larval Lepidoptera) in most terrestrial ecological communities (regions in natural grasslands and woods, or agriculture and forestry). It is known that Goniini has 88 genera in the world and 139 species of 49 genera in China. In this project, Goniini of China will be investigated and studied in taxonomy. The types and other Chinese specimens of Goniini will be examined,a revision of known species and genera and genus-groups including
