Abstract

Methanolic extracts of crude seed oil of Pongamia pinnata (Karanj) showed the maximum growth reduction and antifeedancy against the larvae of S. litura (EC50: 0.11 and 0.21% respectively) and was also most toxic to Trogoderma granarium (EC50: 35.1 μg/insect) whereas karanj leaves (EC50: 19.9 μg/insect) exhibited the toxicity against Tribolium castaneum. Crude seed oil of karanj showed the maximum repellency (EC50: 0.2 mg/cm2) against T. granarium.
