Syrphids have been recognised as important predators of aphids (Ghorpade, 1981; Agarwala et al., 1984). In the mid-hill regions of Himachal Pradesh Eupeodes frequens Matsmura has been found to predate upon Brevicoryne brassicae (L.) (Aphididae, Homoptera) infesting cauliflower. The present study was undertaken to study the life-table and intrinsic rate of increase of E.frequens under laboratory conditions to understand the dynamics of this predator as biological agent of the aphid.
