摘　　要：微孢子虫治蝗是一项持续、低耗、无公害的生物治理蝗害措施,对保护草地生态系统生物多样性具有重要意义,通过对内蒙古达茂旗草地蝗虫不同防治区昆虫群落的组成和结构多样性研究,揭示了化学农药对生物多样性的影响;评价了昆虫蜕皮抑制剂Cascade以及生物制剂微孢子虫对生物多样性保护的作用和意义;分析了主要优势种害虫和潜在的次要害虫,为组建草地蝗虫综合治理体系提供了参考依据。Using Nosema locuste to control locust plagues is a sustainable lowcost biological control measure with no pollution effects on society, and has an important significance in the protection of grassland ecosystem biodiversity Through study of insect community composition and structural diversity in different grassland locust control areas in Dashengqi of Inner Mongolia, the influence on biodiversity was exposed An insect skin shedding inhibitor 'Cascade' was evaluated as well as using Nosema locuste, looking at the protection effect and significance on biodiversity Major dominant pests and potential secondary pests were analyzed, providing a basis for reference for establishing a grassland locust integrated control system
