Abstract: The laboratory studies conducted on the feeding potential of the <em>Coccinellidae</em> predator, <em>Menochilus sexmaculatus</em> (Fabr.) on mustard aphid, <em>Lipaphis erysimi</em> revealed that the neonate grub just after hatching start feeding on chorion of the eggs, and then feeds on the aphids. The feeding potential increased consequently from 1^st, 2^nd, 3^rd, and 4^th instar by consuming an average number of 38.64±0.13, 55.57±0.78, 65.42±0.78 and 75.86±0.55 aphids/day respectively. Maximum number of aphids was consumed by adult of 92.20±1.02 aphids/day.
