摘　　要：梭毒隐翅虫Paederus fuscipesCurtis是一种重要的天敌昆虫。本试验在室内条件下采用浸渍法分别测定了4种杀虫农药在田间常用最低浓度时对梭毒隐翅虫成虫死亡率和捕食功能的影响。试验结果表明,梭毒隐翅虫对10%高效杀虫死最敏感,对22%蚜虱灵、40%氧乐果乳油次之,而18%杀虫双水剂对它的致死作用及捕食功能影响均较小。4种杀虫农药对残存个体捕食功能的影响均超过致死作用。Paederus fuscipes Curtis is a common predatory natural enemy in farmland. The experiment using soaking method tested the mortalities and effects on predatory function of four kinds of common insecticides to P. fuscipes with common lowest concentration in farmland. The experiment results indicate that P. fuscipes is mast sensitive to chlorpyrifos and deltamethrin, less sensitive to imidacloprid and buprofezin and omethoate, but bisultap has least effect on mortality and predatory function. The effects of four insecticides on predatory function of survivals are also stronger than the lethalities.
