Evaluation of Different Plant Oils against Rice Moth, Corcyra cephalonica, Stainton in Stored Groundnut Kernels

Abstract

One of the primary pests believed to cause loss is the rice moth (Corcyra cephalonica, Stainton), which feeds on stored groundnuts. For that biological control measure are ecological relevant over the use of chemical fertilizer. Therefore, the aim of present to assess the effectiveness of various plant oils against the rice moth, the current experiment was carried out. The study was conducted in a laboratory using a completely randomized design with nine treatments and four repetitions. The results was showed that among various plant oils, neem oil at 0.5 per cent was most effective against rice moth as it recorded maximum oviposition deterrence (91.10%), highest reduction in adult emergence (93.28%), lowest longevity of male (1.73 days), as well as female (2.08 days) moth, lowest fecundity (26.98 eggs/female) as well as egg viability (38.50%), minimum weight loss (10.05%) and had no adverse effect on the germination of groundnut kernels after 3 months of storage followed by castor oil at 0.5 per cent.
