Efficacy of different plant products against rice moth (Corcyra cephalonica, Stainton) in rice

Abstract

The present investigation entitled “Efficacy of different plant products against rice moth (Corcyra cephalonica, Stainton) in rice” was carried out under laboratory condition, Department of Entomology, Rajasthan College of Agriculture, MPUAT, Udaipur during august, 2017. The plant products were used viz; neem seed powder, custard apple seed powder, neem leaf powder, karanj leaf powder, custard apple leaf powder, eucalyptus leaf powder @ 2.5gm per 250gm grains of each treatment to observe the larval mortality(at 5 day interval upto 40 days), pupal mortality and adult emergence. It was observed that the highest larval mortality (83.00%), pupal mortality (10.00%) and minimum adult emergence (7.00%) were recorded in rice grains treated with neem seed powder and second highest larval mortality (82.00%), pupal mortality (10.00%) and minimum adult emergence (8.00%) were recorded in rice grains treated with custard apple seed powder after 40 days of pest release. This result revealed that the neem seed powder and custard apple seed powder was most effective among plant products. The minimum larval mortality (68.00%), pupal mortality (6.00%) and maximum adult emergence (26.00%) were recorded in eucalyptus leaf powder.
