Abstract

A commented preliminary checklist of the aphids (Homoptera: Aphididae) of Pakistan and their host plants.

Abstract

A survey of the aphids of Pakistan was carried out during 1987-92. Nearly 300 aphid species are listed, including many of economic importance and with about 60% being recorded for the 1st time for Pakistan. However, the present contribution to the knowledge of the aphid fauna of Pakistan barely involves half of the expected total number of species. A biogeographic general survey shows the great interest of this area placed at the crossroads and bearing elements of Saharo-Sindhian, Irano-Turanian, Indian and East-Palearctic origin. The importance of the Himalayan range as a centre of evolution of the Aphidoidea is underlined by the wealth of (in part still undescribed) endemic species. As far as possible, host plants, life cycle and general geographic distribution are given for every species. A few new taxonomic data are included. Aulacorthum delphiniae is given as a junior synonym of Nasonovia jammuensis and Indoidiopterus as a junior synonym of Neotoxoptera, with Neotoxoptera geranii being a new combination.
