Few plant extracts were screened for their insecticidal activity against Red flour beetle,Tribolium castaneum and Saw toothed grain beetle,Oryzaephilus surinamensis at O.5, 1.0, 2.0 and 5.0 percent concentrations. For T. castaneum the leaf extracts of yellow kaner was most effective (0.03075% R.T.) while Marigold leaf extract was least effective (0.00064% R.T.). Similary forO. surinamensisthe bulb extract of garlic and flower extract of marigold showed maximum (0.03857%R.T.) and minimum (0.00214% R.T.) respectively. Rest all others extracts showed intermediate results against both the pests.
