Abstract:
The present investigation entitled “Efficacy of indigenous plant products on Corcyra cephalonica (Stainton) in stored rice grains” was carried out under laboratory condition which was controlled and maintained at Medinipur during 2020-2021 under the supervision of Dr. Usha Yadav, Assistant Professor, Department of Entomology, SHUATS, Prayagraj, (U.P). The experiment was laid out in completely randomised design with seven treatments which are three replications including T1- Untreated control and viz., T1- Untreated Control T2- Neem leaf powder, T3- Tulsi leaf powder, T4- Karanj leaf powder, T5- Marigold flower powder, T6- Eucalyptus leaf powder, T7- Rynaxypyr (Coragen) on the larval mortality and grain damage and larval orientation of C. cephalonica. The result was revealed that the highest larval mortality (81.67)% after 30 DAR both were recorded in neem leaf powder and it was concluded that the neem leaf powder was most effective. The maximum larval orientation towards treated rice grains after 72h on marigold leaf powder (5.67)% and also revealed that the highest grain damage after 30 days was recorded in untreated control (93.33)% and minimum grain damage on both were recorded in neem leaf powder and Rynaxypyr (Coragen) negligible after 30 days and it was concluded that the neem powder was most effective.
