Infestation of maize stem borer, Chilo Partellus (Swinhoe) in maize stubbles and stalks
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2015, Vol 7, Issue 1
Abstract
The research was conducted to record the infestation of maize stem borer in maize stubbles and stalks in two maize cultivars i.e. local white and hybrid in three different locations of Mardan, Divison during 2012. Results showed highest maize stem borer infestation of 26.7% in stubbles at Palo and lowest of 15.0% recorded at Badder. Highest (24.4%) maize stem borer larval infestation was recorded on hybrid as compared to local white where the percent infestation was recorded lowest (17.2%). Results further revealed maximum mean percent (8.2) of maize stem borer hibernating larvae in Hybrid and minimum (3.2) in local white where as the mean percent of hibernating larvae was recorded maximum (11.8) at Palo and lowest (1.0%) at Badder. In stalks highest infestation occurred at Ghowndo ranged (3-10%), (2-9%) at Palo and (1-9%) at Badder, respectively. The study concluded that percent infestation of maize stem borer in stubbles and the mean percent of hibernating larvae was highest at hybrid variety at Palo which means that the hybrid is more susceptible to maize stem borer infestation. In stalks the maize stem borer infestation was also recorded highest at Palo. For farmers it is recommended to organize the dry stalks before the next cropping season to minimize the emergence of the adults that can assault the new crop.
