摘　　要：[目的]研究牧草害虫捕食性天敌毛婪步甲的生物学特性。[方法]2008年4月初至10月底采集毛婪步甲进行生物学饲养试验,然后进行捕食行为的观察,并测试农药对毛婪步甲的毒杀作用。[结果]毛婪步甲在贵州1年发生1代,以成虫在土壤内过冬。主要以成虫捕食猎物为主,1头成虫24h最大捕食黏虫量6.36头。农药对毛婪步甲前10d毒杀效果明显,后期主要是驱避作用。[结论]该研究可为保护毛婪步甲、防治牧草害虫提供理论依据。[Objective]The paper aimed to study the biological property of pasture pests predators of Harpalus griseus（panzer）. [Method]Harpalus griseus（panzer） was collected to carry out biological feeding trial,predatory behavior was observed and the cytotoxicity of pesticides to Harpalus griseus（panzer） was tested. [Result]Harpalus griseus（panzer）. takes one year to complete its life cycle in Guizhou,the adult overwinters in soils. Adult mainly prey on prey,A adult can maximum prey on armyworm 6. 36 per 24 h within one day,pesticides had an obvious poison effect on Harpalus griseus（panzer）,anaphase mainly had a repellency. [Conclusion]This study can provide a theoretical foundation for protecting Har-palus griseus（panzer） and control pasture pests.
