The relationship between a coccinellid beetle (Coccinella septempunctata L.) and four different aphid species (spinach aphid, Aphis fabae Scopoli; coriander aphid, Hyadaphis coriandri (Das); cabbage aphid, Brevicoryne brassicae L.;pea aphid, Acyrthosiphon pisum Harris) was evaluated in the laboratory in no choice and free choice feeding assays. In the no choice feeding assay, the stages of beetle (adults, 3rd and 4th instar) consumed more aphids than early stages (1st and 2nd instar). In the free choice feeding assay, the consumption of pea aphid (77.647) was statistically high followed by spinach (66.276), coriander (66.14) and cabbage (61.48) aphids. Manly’s preference index suggest that pea aphid was the most preferred (by all stages of C. septempunctata) aphid species followed by coriander, and the cabbage aphid was the least preferred species. The results of the present study revealed predatory potential of C. septempunctata against different aphid species under the laboratory conditions. The results could be helpful in designing biological management strategies for aphids.
