粮食收获后由于虫害而遭受损失,对粮食进出口都是一个严重的问题。使用杀虫剂是当前主要的防治方法。不过,一份最近的调查报告指出,所有主要的仓库害虫已经对一定种类的杀虫剂产生了不同程度的抗药性。同时由于发展新农药的成本高昂,目前要求高质量即不含农药残留量的粮食十分迫切。面临这些问题,现在科学家正在寻找一种不用常规农药来防治粮食仓库害虫的新方法。 After the grain harvest due to pests and losses, the import and export of food is a serious problem. The use of pesticides is currently the main method of control. However, a recent survey pointed out that all major storage pests have had varying levels of resistance to certain classes of insecticides. At the same time, due to the high cost of developing new pesticides, there is an urgent demand for high-quality food that does not contain pesticide residues. Faced with these problems, scientists are now looking for a new way to prevent pests in food warehouses without conventional pesticides.
