EVALUATION OF DIFFERENT BOTANICAL POWDERS AGAINST RICE MOTH, CORCYRA CEPHALONICA IN STORED GROUNDNUT KERNELS

The present experiment was conducted to evaluate the efficacy of different botanical powders against rice moth (Corcyra cephalonica) in stored groundnut kernels.Among various botanical powders, neem leaf powder at 1.25 per cent was proved to be the most effective against rice moth as it recorded maximum oviposition deterrence (90.30%), highest reduction in adult emergence (92.77%), lowest longevity of male (2.53 days) as well as female (2.60 days) moth, lowest fecundity (40.13 eggs/female) as well as egg viability (38.50%), minimum weight loss (8.90%) and had no adverse effect on the germination of groundnut kernels after 3 months of storage followed by karanj leaf powder at 1.25 per cent.
