The cabbage aphid, Brevicoryne brassicae L. is a serious pest of cabbage, but also attacks cauliflower. Turnip. Radish. Mustard etc. affecting their growth and reducing their market value considerably. The role of natural enemies in containing the aphid population is of considerable importance. Recently. Verma and Makhmoor (1987) have reported various species of syrphid preying upon B. brassicae in mid-hill region of Himachal Pradesh. In the present study, efforts were made to determine the natural enemy complex of B. brassicae other than syrphids in and around the Kullu valley (H.P.) during the years 1987-88 from April to June by conducting regular field surveys. Parasitoids and predators so obtained were identified through CIE, London.
