多年来我区草原蝗虫灾害的化学防治主要使用有机磷农药稀释配制成一定浓度的药液进行喷施，以达到消灭蝗虫、保护草原的目的。但因长期使用单一品种，促使某些种类的蝗虫体发生较强的抗药性，导致药效降低，防治费用增高等问题出现。为提高防治效果，扩大应用范围，降低用药成 For many years, the chemical prevention and control of grassland locust disaster in our district mainly uses organic phosphorus pesticide dilution to formulate a certain concentration of chemical solution for spraying so as to eliminate locusts and protect grasslands. However, long-term use of a single species, prompting some species of locust body strong resistance, resulting in lower efficacy, prevention and control costs increase and other issues arise. To improve the control effect, expand the scope of application, reduce the use of drugs
