The present paper deals with the association of aphids with the plants belonging to the family Fagaceae, in India. Sixteen species of plants of this family were found infested with 89 species of aphids belonging to 31 genera and 6 subfamilies, such as Aphidinae (Tribe Aphidini: 5 species; Tribe Macrosiphini: 3 species), Calaphidinae (Tribe Calaphidini: 5 species; Myzocallinini: 7 species), Eriosomatinae (Pemphigini: 1 species), Greenideinae (Cervaphidini: 2 species; Greenideini: 46 species), Hormaphidinae (Cerataphidini: 1 species; Nipponaphidini: 12 species) and Lachninae (Lachnini: 4 species; Tuberolachnini: 3 species) in India. Maximum number of plant species are associated with aphids belonging to the tribe Greenideini while highest number of aphid species (23 aphid species) are colonised on Lithocarpus dealbatus Rehder followed by Quercus incana W. Bartram (10 aphid species), Quercus rubra L. (5 aphid species) and less than 5 number of species on rest of the plant species (Table 1). The highest number of plant species (7 plant species) were colonised by Eutrichosiphum khasyanum (Ghosh & Raychaudhuri) followed by Eutrichosiphum pasaniae (Okajima), Eutrichosiphum pseudopasaniae Szelegiewicz, and Lachnus tropicalis (van der Goot) (5 plant species of each); and rest of the species colonise less than 5 plant species. Among 89 species of aphids colonised on fagaceous plants, 55 species of aphids are associated with its single species.
