摘要
绿僵菌治蝗是一项低耗、无公害、可持续的生物治理蝗害措施,对保护草原生态系统生物多样性具有重要意义。通过对内蒙古锡林郭勒盟草原蝗虫不同防治区昆虫群落的组成和结构多样性调查与研究,揭示了化学农药对生物多样性的负面影响;评价了绿僵菌制剂在保护和调节生物多样性方面的作用;明确了目前的主要优势种害虫和可能上升为主要害虫的次要害虫,对建立草原蝗虫的综合治理和其他害虫控制提供参考依据。
Metarhizium anisopliae 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 investigation on of insect community composition and structural diversity in different grassland locust control areas in Xilinguolemeng of Inner Mongolia,the influence on biodiversity was exposed.Major dominant pests and potential secondary pests were analyzed,which provides a basis for reference for establishing a grassland locust integrated control system.
