苏家屯地区投放赤眼蜂防治玉米螟技术研究

Study on Controlling Corn Borer by Trichogramma in Sujiatun Area

玉米螟是玉米生产上的主要虫害之一,在苏家屯区每年都有不同程度的发生,常年损失在5%~10%左右,2018年损失达20%以上,严重影响玉米产量。苏家屯区历年播种玉米面积约占全区农作物播种总面积的65.6%。为有效控制玉米螟对苏家屯区玉米生产的危害,经过2年试验,通过投放赤眼蜂防治玉米螟,效果显著。该文对赤眼蜂防治玉米螟技术进行总结,以期为玉米生产提供理论参考。

Corn borer was one of the main pests in maize production,which occured in different degrees every year in Sujiatun district.The annual loss was about 5%~10%,and the loss was more than 20%in 2018,which seriously affected maize yield.The planting area of maize in Sujiatun district over the years accounted for about 65.6%of the total planting area of crops in the region.In order to effectively control the harm of corn borer to corn production in our area,after two years of experiment,the effect of controlling corn borer by trichogramma was significant.This paper summarized the technology of controlling corn borer by trichogramma,in order to provide theoretical reference for corn production.
