粘虫因为是能长距离地飞行移动的害虫,会在禾本科各种作物上突然大发生、造成大的危害。事先预测也极困难,目前还没有找到防止其突发的对策。一旦在饲料作物田间发生时,对家畜还有农药残留问题未解决,所以现在还不主张使用药剂防除。笔者在饲料作物上粘虫的生态、耕作防治法研究中,只在杂草多的田间才抓住粘虫 Because armyworms are pests that can move over long distances, they suddenly occur in grasses and cause great harm. It is also extremely difficult to predict in advance, so far we have not found any countermeasures to prevent it from happening unexpectedly. Once the crop occurs in the field of feed crops, there are still problems of pesticide residues in livestock are not resolved, so now do not advocate the use of pharmaceutical control. I feed insects on the armyworm ecology, farming control law study, only in the weeds and more fields to seize the worm
