通过对１９９１～１９９５年调查资料分析：引起大连市玉米螟近几年重发的原因是：①玉米种植密度提高，创造了利于玉米螟发生的小气候和充足的食源；②玉米秸秆处理和转化比例降低，存留量大，虫源基数提高；③抗玉米螟品种缺乏，感虫品种面积过大；④防治方法单一，防效无法保证。据此提出加速玉米秸秆处理和转化、种植抗玉米螟品种、白僵菌封垛、高压汞灯诱杀、释放赤眼蜂和化学防治的综合治理对策
Based on the survey data from 1991 to 1995, the reasons causing the resurgence of Ostrinia furnacalis in recent years in Dalian are as follows: (1) The planting density of corn is increased, creating the microclimate and sufficient food which is conducive to Ostrinia furnacalis occurrence; (2) Lower proportion, large amount of storage, improve the base of insect population; ③ lack of resistant varieties of corn borer, flu insects species area is too large; ④ a single control, prevention can not be guaranteed. Based on this, the countermeasures of accelerating the treatment and transformation of corn stalks, planting corn resistant borer, planting Beauveria bassiana, capturing and killing trichogramma by high pressure mercury lamp and chemical control were proposed
