The predatory potential and biology of Coccinella undecimpunctata L. fed on cowpea aphid, Aphis craccivora Kock have been studied under laboratory conditions (25±2ºC and 60±5% R.H.). The results revealed that mean consumption of aphids per C.undecimpunctata adult was 80.8, whereas, 21.76, 55.67, 107.86 and 231.03 aphids were consumed by a single larva during 1st, 2nd, 3rd and 4th instars, respectively. A single female laid 195.0±13.10 eggs during entire life period. The egg hatching was 96.3% while 82.0 % larvae survived up to pupal stage. Total larval and pupal duration was 23.4±0.35 and 5.3±0.56 days, respectively. Mean percent emergence in male and female was 36.6±2.98 and 56.6±4.21, respectively. Male to female sex ratio was recorded 1:1.5.
