稻螟是我国稻区重要害虫之一,常年发生量大,为害严重,给水稻高产稳产带来威胁。在治螟中,由于长期大量使用化学农药,致使螟虫不同程度产生抗药性,防治效果显著下降;治螟用药量大,药剂供不应求;另一方面大量使用化学农药不仅污染水源和土壤,杀伤有益昆虫和水生生物,同时,农药在农副产品中的残毒危害人畜健康。因此,探索新的治螟措施是十分必要 Rice stem borer is one of the important pests in the rice area of ​​our country, perennial occurred large amount of serious damage, to the high and stable yield of rice threatened. In the treatment of borer, due to long-term large-scale use of chemical pesticides, resulting in different degrees of resistance of stem borer insects, prevention and control of a significant decrease in the amount of governance borer medication, pharmaceutical supply in short supply; the other hand, extensive use of chemical pesticides not only pollute the water and soil, killing beneficial insects And aquatic organisms, at the same time, residues of pesticides in agricultural products endanger the health of humans and animals. Therefore, it is very necessary to explore new measures for controlling stem borers
