The toxicity of six insecticides (Advantage ® , Pyramids ® , Polo ® , Imidacloprid ® , Match ® and Mospilon ® ) on Brevicoryne brassicae (Hemiptera: Aphididae) and its parasitoid, Diaeretiella rapae (Hymenoptera: Braconidae) were evaluated under constant laboratory conditions (25±2 ºC; with 65-70% R.H.). All the tested insecticides were lethal against B. brassicae with the passage of time at highest concentration. Maximum mortality was observed in Polo ® and minimum in Mospilon ® followed by

All the LC50s were lethal against its parasitoid with maximum mortality at 48 HAT (Hours after treatment) and minimum in all insecticides at 12 hours after treatment. The maximum mortality (100%) were Introduction Brassica crops are attacked by number of insect pests including cabbage aphid, Brevicoryne brassicae L., (Homoptera: Aphididae) all over the word [1, 2].
