摘　　要：在已有标本采集记录和资料的基础上 ,从分类阶元、寄主植物、寄生部位、动物地理区系的角度探讨了甘肃省蚜虫类的物种多样性。结果表明甘肃省蚜虫种类丰富 ,已知 9科 90属 2 2 0种 ;分布在华北区、蒙新区、青藏区、华中区和西南区 ,其中华北区、蒙新区和青藏区的种类最为丰富 ,因此甘肃省蚜虫区系以古北界成分为主 ;寄主植物种类繁多 ,已知有 46科 111属 ;寄生部位多样化 ,以叶片和茎为主要为害部位。另外就甘肃省所处地理位置的特殊性 。This paper reviews the species diversity of aphids in Gansu Province, China. Specimen records and published literature were used to determine taxa, host plants, locations and geographical and faunistic features of aphid habitat. The results indicate that aphid species in Gansu Province are plentiful with 220 known species belonging to 90 genera and 9 families distributed in 5 regions: North China, Meng-Xin, Qinghai-Tibet, Central China and South Western China. There are three regions, including North China, Meng-Xin, and Qinghai-Tibet that have high species diversity. In Gansu Province, most species have a Palaearctic distribution. Host plants are diverse, belonging to 111 genera and 46 families. Various parts of plant anatomy are infested but aphids usually feed on leaves and young twigs. In one special geographical location in Gansu Province had unusually high species diversity at the junction of several geographical regions. More detailed research is needed to clarify this edge effect and variation in distribution patterns.
