摘要： 为有效地实施玉米害虫的综合治理，通过田间试验研究安徽淮北玉米产区33 个常用玉米品种对玉米螟的抗虫性。结果表明，不同玉米品种的抗螟性之间存在明显的差异，同一品种在心叶期和穗期的抗螟性强弱亦不相同。在玉米心叶期，‘中农大311’、‘中科11’、‘登海3 号’、‘东单80’、‘蠡玉16’、‘郑单23’、‘济单8号’、‘滑玉13’等8个品种的抗螟性较强。在玉米穗期，‘浚单20’、‘齐单1号’、‘中科4号’、‘农大108’、‘鲁单6018’等5 个品种的抗螟性较强。心叶期和穗期的综合抗螟性较强的10 个玉米品种排序为‘中农大311’、‘中科4号’、‘济单8号’、‘郑单23’、‘郑单958’、‘齐单1号’、‘中迪985’、‘农大108’、‘蠡玉16’、‘登海3号’。

Abstract: In order to practice integrated management of corn insect pests effectively, a field experiment was made to study the resistance of 33 corn varieties to corn borer (Ostrinia furnacalis) in the area to the north of the Huaihe River of Anhui Province in this paper. The results showed that there were evident differences of the resistance to corn borer among different corn varieties and the resistant levels to corn borer in the whorl leaves stage and the ear stage of the same corn variety were also different. In the whorl leaves stage of corn, the resistance to corn borer of 8 corn varieties,‘Zhongnongda 311’,‘Zhongke 11’,‘Denghai 3’,‘Dongdan 80’,‘Liyu 16’,‘Zhengdan 23’,‘Jidan 8’and‘Huayu 13’was relatively high. In the ear stage of corn, 5 corn varieties of‘Xundan 20’,‘Qidan 1’,‘Zhongke 4’,‘Nongda 108’and‘Ludan 6018’had relatively high resistance to corn borer. The order of the comprehensive resistance of different corn varieties to corn borer in the whorl leaves stage and the ear stage was as follows:‘Zhongnongda 311’,‘Zhongke 4’,‘Jidan 8’, ‘Zhengdan 23’,‘Zhengdan 958’,‘Qidan 1’,‘Zhongdi 985’,‘Nongda 108’,‘Liyu 16’,‘Denghai 3’.
