The present article deals with the association of aphids (Hemiptera: Aphididae) with the plants belonging to the families of the orders of basal eudicots (orders Buxales, Proteales and Ranunculales) and also the families of two early orders of core eudicots, Saxifragales and Vitales in India. The order Buxales include only one family Buxaceae of which only 2 species of plants are associated with 3 species of aphids. In the order Proteales only a single species of lotus, Nelumbo nucifera Gaertn. of the family Nelumbonaceae is recorded as host plant of a single species of aphid, Rhopalosiphum nymphaeae (Linnaeus) in India. In the order Ranunculales, 27 species of plants under 15 genera included in 5 families are associated with 47 species of aphids belonging to 25 genera. Among the Indian flora of Saxifragales and Vitales, only 10 and 3 species are found associated with 14 and 10 species of aphids, respectively. In all, 43 species of plants belonging to 12 families of 5 orders are associated with 67 species of aphids belonging to 37 genera and 8 subfamilies. Four species of the aphids belonging to the genus Liosomaphis Walker are specifically associated with basal eudicots order Ranunculales. Two species, Aphis (Aphis) gossypii Glover, 1877 and Myzus (Nectarosiphon) persicae (Sulzer, 1776) are highly polyphagous on early eudicots. Total 37 species of aphids are associated with a single species of host plants belonging to above mentioned orders.
