摘　　要：梭毒隐翅虫Paederus fuscipesCurtis是农田常见的捕食性天敌昆虫。在室内条件下采用浸渍法分别测定了5种常用杀虫农药对梭毒隐翅虫成虫的杀伤情况。试验结果表明:10%毒.溴乳油对梭毒隐翅虫的毒力最强,40%氧化乐果乳油毒力次之,22%噻.吡可湿性粉剂和50%辛硫磷+氰戊菊酯毒力较弱,18%杀虫双水剂(bisultap)毒力最弱。Paederus fuscipes Curtis is a common predatory, natural enemy in farmland. Using the means of soaking under laboratory conditions, we determined the inflict casualties of five kinds of common pesticides on Paederus fuscipes Curtis. The results of bioassay showed that： toxicity of 10% chlorpyrifos plus deltamethrin is the strongest, 40% omethoate is the second strongest, 22% imidacloprid plus buprofezin and 50% phoxim plus fenvalerate are comparatively weak,and that of 18% bisultap aqueous solution is the weakest.
