摘　　要：从分类群的多样性、寄主植物多样性和地理分布多样性 3个方面系统研究了中国斑蚜科蚜虫的物种多样性。分类群的多样性从亚科、属和种 3个不同阶元进行了描述。寄主植物的多样性体现在 :不同蚜虫类群寄主植物的丰富度 ,其中角斑蚜亚科的寄主最为丰富 ,包括 14个科的植物 ;同类寄主植物上取食蚜虫的多样性 ,其中桦木科植物上有 15个属的蚜虫取食。在地理分布上 ,斑蚜科在中国主要分布在古北界的 4个区和东洋界的 3个区 ,以古北界的成分占优势 ;而且华北区种类最为丰富 ,其次为东北区、华中区、华南区和蒙新区。属的分布类型可分为 12种 ,分别为中国特有分布型、东亚特有分布型、古北界特有分布型、东洋界特有分布型、全北界分布型、全北界和澳洲界共有分布型、古北界和东洋界共有分布型、全北界和东洋界共有分布型、全北界和非洲界共有分布型、古北界、东洋界和非洲界共有分布型、东洋界和澳洲界共有分布型及东洋界、非洲界和澳洲界共有分布型 ,其中以东亚特有分布型为最丰富 ,有 10个属 ;其次为全北界分布型 ,有 7个属 ,同时中国的特有成分也相当高 ,涉及 6个属。纵观整个中国斑蚜科属级阶元的分布类型 ,中国的斑蚜科以全北界成分为主 ,其次为东洋界成分。斑蚜科在中国的地理分布 ,由东向西 ,种类越来越?This paper describes the species diversity of Chinese Drepanosiphidae from the following three aspects: taxa diversity, host plants diversity, and geographical distribution diversity. Taxa diversity is expressed in levels of subfamilies, genera and species. Host plants diversity is expressed in terms of the number of host plants in different aphid groups. The Myzocallidinae had the greatest host plant diversity (14 plant families). Aphid diversity is expressed in terms of the number of aphid species feeding on the same host plants. The plant family Betulaceae is infested by 15 genera of aphids. In terms of geographical distribution, the Drepanosiphidae in China are mainly found in 4 subregions of the Palaearctic Region, and 3 subregions of the Oriental Region. Groups in the Palaearctic Region are distinctly predominant; in addition, species in North China are the most plentiful, relatively fewer species are found in the Northeast, Central China, South China and the Mongolia-Xinjiang subregions. The distribution patterns of genera are segregated into 12 categories, i.e. Chinese endemic distribution pattern, East Asian endemic distribution pattern, Palaearctic Region endemic distribution pattern, Oriental Region endemic distribution pattern, Holearctic region endemic distribution pattern, distribution pattern in Holearctic and Australian Regions, distribution pattern in Palaearctic and Oriental Regions, distribution pattern in Holearctic and Oriental Regions, distribution pattern in Holearctic and African Regions, distribution pattern in Palaearctic, Oriental and African Regions, distribution pattern in Oriental and Australian Regions, and distribution pattern in Oriental, African and Australian Regions. Among them the East Asian endemic distribution pattern is predominant, including up to 10 genera; the second is Holearctic distribution pattern, which have 7 genera; in the meantime, Chinese endemic groups are plentiful, which have 6 genera. On the whole, the species number of Chinese Drepanosiphidae is fewer and f
