Efficacy of new insecticide molecules against mango leaf webber, Orthaga exvinacea Hampson (Pyralidae: Lepidoptera)

Abstract

The field experiment was conducted at Regional Horticultural Research and Extension Centre (RHREC), Kumbapur farm, Dharwad during 2018-19 to evaluate the efficacy of new molecules of insecticides against mango leaf webber in the established mango orchard. The cumulative mean of pest incidence fifteen days after second spray revealed that all the treatments showed comparative decrease in spread of the mango leaf webber infestation, but the treatment chlorantraniliprole 18.5% SC recorded least number of active webs per tree (2.17) and least number of larvae per web (2.82) and same was found effective in the management of O. exvinacea infesting mango over untreated control.
