The feeding potential of Coccinella septempunctata L. was studied under laboratory conditions on Hyadaphis coriandri. The first, second, third and fourth instar grubs of C. septempunctata were found to consume 27.0 ± 5.35; 34.22 ± 4.29; 91.44 ± 25.13 and 237.37 ± 88.37 aphids, respectively. A grub consumed 380.62 ± 81.66 aphids during its total life span. The adult male and female beetles consumed 1345.0 ± 227.66 and 1948.0 ± 123.4 aphids during their adult longevity with daily ability to consume 52.5 ± 4.74 and 63.5 ± 10.87 aphids, respectively.
