ABSTRACT

Maize (Zea mays L.) is one of the most important nutritious crops in the world. In Pakistan, this is the 3rd largest cultivated crop. The yield of maize is greatly affected by many insect pests and maize borer (Chilo partellus Swinhoe) has been identified as one of the major limiting factors to maize production throughout the world. As the information regarding its distribution is lacking therefore, its incidence and prevalence was determined in seven major maize growing districts of Punjab during 2016. The maximum overall incidence of maize borer (12%) was recorded in Khanewal district followed by Multan (6%) while it was the minimum (1%) in district Okara. On the other hand, maximum prevalence of maize borer was observed in district Vehari (100%) followed by districts of Khanewal and Multan (73%) while minimum prevalence of 33% was recorded in district Sahiwal. As regards cultivars, maximum incidence of maize borer (13%) was recorded on cultivar 8621 followed by C1543 (10%) and the minimum was found on cultivar 71R88 and Desi. No infestation of the borer was observed on cultivars 88R88, 30T87 and 15P43. It is concluded that maize borer has been found fairly distributed in the major growing districts of Punjab; hence strict control measures should be adopted to minimize its damage. Some cultivars were found resistant to the borer infestation and are recommended for cultivation.
