Abstract

The insecticidal properties of leaf extracts of Carica papaya, Leucas aspera and seed extracts of Datura stramonium and Mucuna pruriens were evaluated against Aphis gossypii Glover (Hemiptera: Aphididae) under laboratory conditions. The mortality of aphids (80.0%) was more from D. stramonium seed extract (10ml/l) with LD50 of 0.39% followed by C. papaya leaf extract which caused mortality of 72.5% (10ml/l) with LD50 0.96%. The mortality of A. gossypii in M. pruriens seed extract was 70.0% with LD50 0.65% however the mortality was found to be non significant in L. aspera extract.
