摘　　要：通过在陕西省韩城市黄河滩区对不同有效成分、不同剂型的常用化学农药、生物农药、植物源农药共27种药剂进行防治东亚飞蝗的大田喷施试验和田间笼罩试验,筛选出可供蝗虫不同密度区使用的不同农药种类,为有效进行生物防治和控制高密度区飞蝗提供良好的防治依据。试验筛选出用于飞蝗高密度区速效性较好的农药8种,施药后8d防效达100%且费用在22.5元/hm2以下的药剂7种,同时试验发现植物源农药1%苦皮藤素EC可满足蝗区生物多样性的保护要求,但生物类药剂防治效果普遍不及化学农药,建议将此类药剂和低毒的化学药剂复配来达到防治要求。The effect of the 27 insecticides from chemical pesticides, the biocide and the pesticide stemming from botany with different effective components and different formulation most in use which specialize in eliminating oriental migratory locust shrouding the fields in Yellow-River beach area Hancheng County, Shaanxi Province were tested in filed spraying and filed shrouding. The test was screened out the pesticides in different locust density area, and provided evidence for effective to biological control and control the high density area. The test was screened out 8 pesticides with high rapidly available used in high locust density areas. And 7 pesticides control effect reached 100% and costs under 22.5 yuan/ha. Moreover, Celastrus angulatus 1% EC can meet the requirement of biodiversity in locust area. But the results indicated that the efficacy of biological agent still can not attach chemical pesticides. The require of control still advised it to remixed with low toxicity pesticides.
