Feeding potentiality of Menochilus sexmaculatus Fab. on different aphid species

Abstract

To evaluate predatory efficacy of Menochilus sexmaculatus Fab. on mustard aphid (Lipaphis erysimi Kalt.), lucerne aphid (Therioaphis maculata Buckton), indianbean aphid (Aphis craccivora Koch), fennel aphid (Hydaphis coriandari Das), cotton aphid (Aphis gossypii Glover), calotropis aphid (Aphis nerri Boyer), cabbage aphid (Brevicoryne brassicae), a laboratory experiment was escorted at 27.86 ± 3.85 0C temperature and 48.16 ± 6.41 per cent relative humidity (RH) during the investigation. During total larval period, the grubs of M. sexmaculatus consumed significantly maximum aphids of A. craccivora (132.53), whereas, it consumed minimum aphids of B. brassicae (110.60). In case of adults, it fed more number of A. nerri (423.12) as compared to other aphid species.
