摘要
以松突圆蚧为试虫,采用浸液法测定了蚧螨灵、安民乐及木虱净对松突圆蚧1龄若虫的毒力.根据共毒因子法确定蚧螨灵与安民乐混配为最佳配伍;根据共毒系数法确定蚧螨灵与安民乐以浓度比13/10为最佳配比,其增效作用明显,其增效倍数为3.05.
The toxicities of petrol, chlorpyrifos, cypermethrin and their mixtures against 1st instar nymphae of Hemlberlesia pitysophila Takagi were tested with dipping method. According to the cotoxicity, petrol and chlorpyrifos proved to be the optimal combination. After screening, mixture of petrol and chlorpyrifos at the ratio of 13/10 had the highest cotoxicity coefficient and the synergism was of 3.05 times.
