Abstract:
The different plant products viz., neem oil, castor oil, mustard oil, groundnut oil, karanj oil (0.1 & 0.5 ml or g / 100 g of seeds) and neem leaf powder, karanj leaf powder, aak leaf powder and datura leaf powder (1.0 and 2.5 g/ 100 g seeds) when admixed with cowpea grains proved to be causing adverse effect on adult emergence of C. chinensis and reduces grain damage and weight loss by this pest. The neem oil was the best treatment to enhance the developmental period and reducing the adult emergence and ovipositional potential, while datura leaf powder was least effective treatment. The per cent grain damage and weight loss were minimum in neem oil and maximum in datura leaf powder. No adverse effect of tested plant products was observed on the germination of cowpea seeds up to 90 days of treatment.
