Predatory potential of Coccinella septempunctata L. on cotton aphids (Aphis gossypii Glov.) was studied under laboratory conditions at 21 plus minus 1 degree centigrade and 70 plus minus 5 percent relative humidity. Both adult and larva of predator voraciously consumed on an average, 60, 56 and 141.01 aphids per day, respectively and the total developmental period was noted to be 18.75 days.
