Abstract

A roving survey in maize growing mandals in Krishna and Guntur districts during kharif 2017-18, kharif 2018-19 to record the incidence and damage per cent of Chilo partellus (swinhoe) in the farmer fields. In Krishna district, the maximum leaf infestation was observed in Musunuru mandal in 2017-18 (20.33%) and 2018-19 (24.99) and lowest infestation is recorded in Veerullapadu mandal in 2017-18 (8.59%) and 2018-19 (11.92). In Guntur district, the maximum leaf infestation was observed in Pedanandipadu mandal in 2017-18 (22.68%) and 2018-19 (24.11) and lowest infestation is recorded in Narsaraopet mandal and in 2017-18 (9.84%) and 2018-19 (14.91). However, overall mean infestation was high in Guntur district in kharif 2017-18 (16.68%), 2018-19 (21.56%) than in Krishna district in kharif 2017-18 (13.03%) and 2018-19 (17.76%).The per cent dead hearts, stem tunneling, no of larvae, no of pupae and exit holes also followed the same trend.
