Biology and feeding potential of Coccinella septempunctata Linnaeus was studied in the laboratory at 27 ± 2°C and 70 ± 5% RH on mustard aphid, Lipaphis erysimi Kaltenbach. The mean fecundity was 357.45 ± 22.41 eggs per female while ovipositional period, incubation period, larval period, pupal period, total developmental period (egg to adult) and adult longevity were 4.32 ± 0.26, 4.40 • 0.22, 10.95 ± 0.35, 5.35 ± 0.15, 20.70 ± 0.72 and 122.90 ± 3.12 days, respectively. The mean feeding potential of grub and adult was 50.38 • 1.56 and 83.54 • 1.15 aphids per day per individual, respectively.
