Abstract: Eight plant products, viz. neem leaf powder, NSK powder, curry leaf powder, custard apple leaf powder, citrus peel powder, turmeric powder, begunia leaf powder and karanj leaf powder, each @ 5 g/kg seeds were used for management study of Corcyra cephalonica on two sesamum varieties (Smarak and Amrit). Highest larval mortality, pupal mortality and minimum adult emergence were recorded on seeds treated with NSK powder up to a tune of 81.67%, 8.33% and 10.00% as compared to 5.00%, 0% and 95.00% in control in Smarak whereas 83.33%, 6.67% and 10.00% with respect to 6.67%, 0% and 93.33% in control in Amrit respectively. NSK powder treated sesame seeds showed highest germination of 91.67% in Smarak and 92.00% in Amrit. Per cent adult emergence of Corcyra cephalonica and weight loss of seeds were recorded on three sesamum varieties, viz. Smarak (white), Amrit (brown) and Prachi (black) after two months of infestation. Variety Prachi showed minimum infestation by Corcyra cephalonica exhibiting lowest adult emergence (36.67%) with highest phenol (2.72 mg/g) and protein (17.10%) content as compared to variety Smarak (93.67%), where phenol and protein content was 1.30 mg/g and 13.74%, respectively. In Amrit, the adult emerged was recorded 85.33%.
