摘　　要：[ Objective] The paper aimed to study the biological property of predatory enemy of Harpalus griseus （panzer） against pasture pests. [ Method] H. griseus was collected to carry out biological feeding trial during late April to late October in 2008, predatory behavior was observed and the poisoning effect of pesticides on H. griseus was tested. [ Result] H. gdseus occurred generation in one year in Guizhou and overwintered in the soil in the form of adult. Adult was the main form to prey the quarry. One individual adult of H. griseus could mostly prey armyworm for 6.36 heads within 24 h, pesticides had obvious poison effect on H. gdseus in the former 10 d, while it mainly had repellent effect in the latter period. [ Conclusion] This study could provide theoretical foundation for protecting H. griseus and controlling pasture pests.[ Objective] The paper aimed to study the biological property of predatory enemy of Harpalus griseus （panzer） against pasture pests.
