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 results showed that the first, second, third and fourth instar larva consumed an average of ± , ± , ± and ± aphids, respectively. The total larval consumption was ± aphids during its total developmental period when reared on A. pisum. The mean daily consumption of first, second, third and fourth instar larva was ± , ± , ± and ± aphids, respectively. The consumption of male and female adults of H. octomaculata was ± and ± aphids, respectively. Per day consumption of male and female adults was ± and ± aphids, respectively. The total consumption of H. octomaculata during entire lifespan was ± aphids when fed on A. pisum. | Predatory potential of spotted ladybird beetle, Harmonia octomaculata (Fabricius) (Coccinellidae: Coleoptera) on Lucerne aphid, Acyrthosiphon pisum (Harris) (Aphididae: Hemiptera) under Laboratory Conditions
