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.

Abstract


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.
