Substantial harm to ecosystems from the use of chemical pesticides has led to an increasing interest in the use of biopesticides to control grasshoppers in rangelands, including China. One such potential biopesticide for control of grasshoppers is the fungus . In this study, the dynamics of aboveground natural enemies of grasshoppers and arthropod diversity 0-9 years after application of were investigated in rangeland in Qinghai Plateau, China. We found that the number of species and of individuals of aboveground natural enemies increased by 17-250% and 40-126%, respectively, after spraying , and that the main natural enemies showed three peaks after treatment. The conventional indices of species diversity (H') and evenness (J') increased by 11-267% and 13-171%, respectively, after treatment with . The results showed the positive effects of on aboveground natural enemies and biodiversity in an arthropod community in Chinese rangeland. is thought to be a safe biological control agent for grasshopper management in Northwestern China.
化学农药的使用对生态系统造成了严重危害，这使得包括中国在内的人们对使用生物农药来控制牧场蝗虫的兴趣日益浓厚。一种潜在的用于控制蝗虫的生物农药就是这种真菌。在本研究中，在中国青藏高原的牧场中，研究了施用该真菌后0至9年蝗虫地上天敌的动态以及节肢动物多样性。我们发现，喷洒该真菌后，地上天敌的物种数和个体数分别增加了17%至250%和40%至126%，并且主要天敌在处理后出现了三个峰值。处理该真菌后，物种多样性（H'）和均匀度（J'）的传统指标分别增加了11%至267%和13%至171%。结果表明该真菌对中国牧场节肢动物群落中的地上天敌和生物多样性具有积极影响。该真菌被认为是中国西北部蝗虫管理的一种安全生物防治剂。
