Dynamics of Aboveground Natural Enemies of Grasshoppers, and Biodiversity after Application of Paranosema locustae in Rangeland
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 abovegro...

. 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

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. |
