杀虫双对梭毒隐翅虫捕食功能的影响

Effect of Bisultap on Predatory Function of Paederus fuscipes Curtis

梭毒隐翅虫Paederus fuscipesCurtis是一种重要的天敌昆虫。在室内条件下,采用浸渍法测定了18%高效杀虫双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,18%高效杀虫双对梭毒隐翅虫的致死作用及捕食功能影响均较小,但对残存个体捕食功能的影响超过致死作用。

Paederus fuscipes Curtis is a common predatory natural enemy in farmland. The maceration was used under laboratory conditions to test the mortalities and effects on predatory function of P. fuscipes Curtis with bisultap＇s common lowest density in farmland. The experiment results indicate that bisultap has less effect on mortality and predatory function of P. fuscipes, but the effects on predatory function of survival individuals are stronger than ttat on lethality.
