Predatory potential of Coccinella undecimpunctata L. (Coleoptera, Coccinellidae) on Aphis craccivora Koch. (Hemiptera, Aphididae) in Ladakh, India

Predatory potential of all instar larvae and adults of Coccinella undecimpunctata (Coleoptera, Coccinellidae), using Aphis craccivora Koch (Hemiptera, Aphididae) was assessed in laboratory settings. The study, conducted with varying aphid densities in rearing jars, showed a significant increase in prey consumption as aphid density rose. Furthermore, prey consumption heightened with larval development, with 4th instars devouring more aphids compared to earlier instars. Female adults exhibited greater aphid consumption than males. Deploying both 4th instar larvae and adults could enhance pest suppression.
