回顾了1990年以来中国中生代昆虫化石研究的新进展，简述了我国学者在古昆虫分类学、昆虫内部形态学、昆虫系统学、古生态学、昆虫生物地层学、昆虫区系的历史演变、生物古地理学、昆虫与植物的关系等8个方面取得的突出贡献,并给出了我国发现的世界最低层位昆虫科级类群表。

Progress in the study of Mesozoic fossil insects during the last decade in China

During the last decade abundant Mesozoic fossil insects have been collected from China. More than 100 papers and monographs, most of them focused on taxonomy, have been published. In this paper the history, current status and some problems on the taxonomic researches of Mesozoic fossil insects are reviewed briefly. The important results achieved by the Chinese palaeoentomologists on biodiversity, internal morphology, phylogeny of Raphidioptera, biogeography, biostratigraphy, ecostratigraphy, co evolution between pollinating insects and angiosperms are introduced. The table of the oldest insect families in the world found from China is given. The alimentary canal of fossil stick insects from Liaoning Late Jurassic rocks are the first authenticated records of internal anatomy in Palaeoentomological history. It was in 1994 that the cladistic method was first used to study familial phylogeny of fossil and living snake flies in China. The first non marine ecostratigraphic research was made in dividing Late Mesozoic strata of Fengning, Hebei Province, and revealed a general pattern of basin evolution which appears in many other sections of Northeast China. The fossil anthophilous brachycera found from the Yixian Formation of Western Liaoning demonstrated that the flowers were in existence in Late Jurassic and represented by at least two different types of flowers. The East Asia, especially Northeast China, is one of the origin places of angiosperms.
