ABSTRACT
The present work regarding the overwintering population of maize stem borer Chilo partellus (Swinhoe) at larval stage was conducted in order to determine degree of overwintering population and the level of infestation of this pest at different localities of Azad Kashmir. Off 1796 stubbles of maize, present findings showed that over all high population of C. partellus (29.1%) larvae was recorded from locality Chota Gala while the lower (18.73%) was from Rawalakot locality. Whereas greater population (27.77%) of overwintering was found on the stubbles of maize genotype Kashmir Gold than Sarhad White (20.75%). A significant difference in overwintering population was found among all the studied localities. The percentage of infestation (on the basis of exit hole on stubbles) caused by C. partellus was significantly (P<0.001) high (27.77%) on Kashmir Gold than on the Sarhad White (15.99%) in all the studied areas. No clear relationship was found between the stem thickness and the overwintering population of maize stem borer or its infestation.
