| 摘 要： | 以蝗虫微孢子虫为主的治理蝗虫的配套技术，在青藏高原蝗害治理中发挥了重要作用，能有效地控制蝗虫灾害，不污染环境，对自然天敌没有杀伤作用，保护了草地生态系统的生物多样性．特别是蝗虫自然天敌的生物多样性；而运用化学农药治理蝗虫，天敌被大量杀伤，破坏了草原生态系统的生物多样性，蝗灾发生的频率增加。

| Abstract: | Recombined technology of controlling grasshopper using Nosema locustae mainly have been applied in the Qing Zang altiplano for tens of years. Nosema locustae can control effectively grasshopper. It doesn't cause pollution to rangeland, and not hurt natural enemy. Nosema locustae can protect the biological diversity of grassland, especially diversity of natural enemy of grasshopper. The pesticide can kill a great number of grasshopper's natural enemies, destroy the diversity of grassland, the frequency this disaster happen is going up. |
