The experiment was conducted at PG Research Laboratory, Department of Agricultural Entomology, N.M. College of Agriculture, Navsari Agricultural University, Navsari. The results revealed that mean consumption of aphids per larva of Propylea sp. was 10.16 ± 1.93, 26.66 ± 7.59, 52.86 ± 12.87, 75.06 ± 4.32 aphids were consumed during 1st, 2nd, 3rd and 4th instars, respectively. Total larval consumption was 164.74 ± 26.71 aphids. A male beetle consumed 475.34 ± 34.09 aphids. While, female beetle consumed 659.96 ± 47.47 aphids during adult period. Total feeding potential of Propylea sp. on A. pisum was 732.39 ± 36.74 aphids.
