ABSTRACT
In order to practice integrated management of com insect pests effectively, a field experiment was made to study the resistances of 33 com varieties to com borer ( Ostrinia jumacalis) in the com area to the north of the Huaihe River in Anhui Province. The results showed that there were evident differences in resistances of different com varieties to com borer and the resistant levels of the same com variety to com borer were also different in the whorl stage and the ear stage. In the whorl stage of com, eight com varieties, 'Zhongnongda 311', 'Zhongke 11', 'Denghai 3 ' , 'Dongdan 80 ' , 'Liyu 16 ' , 'Zhengdan 23 ' , 'Jidan 8 ' and 'Huayu 13 ' preformed relatively stronger resistance to com borer. In the ear stage of com, five com varieties of 'Xundan 20 ' , 'Qidan 1 ' , 'Zhongke 4 ' , 'Nong-da 108 ' and 'Ludan 6018 ' showed relatively stronger resistance to com borer. The comprehensive resistances of ten com varieties to com borer in the whorl stage and the ear stage successively were 'Zhongnongda 311 ' > 'Zhongke 4' > 'Jidan 8' > 'Zhengdan 23' > 'Zhengdan 958 ' > 'Qidan 1 ' > 'Zhongdi985' > 'Nongda 108 ' > 'Liyu 16 ' > 'Denghai 3 '.
