　　以华北地区广泛种植的玉米品种郑单958、先玉335和浚单20为供试品种，研究棉铃虫和玉米螟危害后对玉米穗腐病发生的影响。结果表明，在降水量大、环境相对湿度高的条件下，玉米螟危害对玉米穗腐病的发生影响较大；而在降水量小、环境相对湿度低的条件下，棉铃虫危害对玉米穗腐病的发生影响较大。相同害虫危害条件下，降水量大、相对湿度高的气候条件更有利于玉米穗腐病的发生。

The influence of cotton bollworm and corn borer on ear rot in corn was studied. The test varieties were Zhengdan958, Xianyu335 and Jundan20 which widely grown in North China. The result showed that the damage done by corn borer had more effect on ear rot in corn on the conditions of high rainfall and high humidity;however, cotton bollworm had more destructive effect on the conditions of low rainfall and low humidity. For one kind of insect, the ear rot was in favor of the condition of high rainfall and high humidity.
