Abstract:
Studies on predatory potential of larva and adult of C. Sexmaculata on A. craccivora was carried out under laboratory conditions during January 2022 to March 2022 at Navsari Agricultural University, Navsari. The mean per day consumption of the first, second, third and fourth instar was 8.42±1.86, 10.21±3.34, 16.13±2.47 and 36.32±3.78 aphids, respectively. The mean total consumption of first, second, third and fourth instar was 10.78±2.71, 22.48±4.40, 36.78±6.93 and 119.12±18.18 aphids, respectively. The total larval consumption was 189.16±25.28 aphids during its developmental period when reared on A. craccivora. The mean per day consumption in female adults of C. sexmaculata was 35.54±11.66 aphids while in males it was 32.67±10.92 aphids. The mean total consumption in female and male adults was 760.62±49.33 aphids and 555.4±41.63 aphids, respectively.
