Abstract:

Studies on predatory potential of larva and adult of H. octomaculata on A. pisum was carried out under laboratory conditions during January 2018 to April 2018.The results showed that the first, second, third and fourth instar larva consumed an average of 15.72 ± 2.66, 25.72 ± 4.79, 53.58 ± 10.93 and 88.94 ± 14.79 aphids, respectively. The total larval consumption was 183.96 ± 17.97 aphids during its total developmental period when reared on A. pisum. The mean daily consumption of first, second, third and fourth instar larva was 12.09 ± 3.03, 14.11 ± 3.36, 21.61 ± 5.60 and 25.38 ± 4.88 aphids, respectively. The consumption of male and female adults of H. octomaculata was 1464.24 ± 76.40 and 1584.58 ± 80.92 aphids, respectively. Per day consumption of male and female adults was 53.86 ± 3.56 and 57.77 ± 6.59 aphids, respectively. The total consumption of H. octomaculata during entire lifespan was 1708.37 ± 58.63 aphids when fed on A. pisum.
