The plant oils and extracts viz., Neem oil, mustard oil, castor oil and Neem seed kernel extract each at three concentrations (, and 10%) and an insecticide check malathion 50 EC ( and ) were evaluated by impregnating the gunny bags against Corcyra cephalonica Stainton (Lepidoptera: Galleriidae). The adult emergence, grain damage and weight loss were recorded after 270 days of storage pearlmillet, Pennisetum glaucum (Linn.). The adult emergence decrease with the increase in the concentration of test plant oils. Among the plant oils and extracts, the mean adult emergence ( adults) was observed in NSKE followed by Neem oil ( adults), mustard oil ( adults) and castor oil ( adults) per cent dose. | Evaluation of plant products as surface protectant of packaging materials against corcyra cephalonica staint. in stored pearlmillet pennisetum glaucum (Linn.)
