摘　　要：将40%乐果乳油配制成0.2%质量分数药液喷施柞树叶面,进行乐果在柞叶中的动态残留分析试验。结果表明,随着施药后采样间隔期的延长,柞叶中乐果的残留量逐渐减少,消解动态符合一级动力学方程,半衰期为69.3 h。在柞蚕饰腹寄蝇病防治中,一定要把握好施药时期。40%of dimethoate EC was prepared into 0.2%liquid and sprayed on the surface of tussah leaves,and the dynamic residue analysis test of dimethoate in tussah leaves was carried out.The results showed that the residual amount of dimethoate in oak leaves gradually decreased with the extension of the sampling interval after spraying,and the digestion dynamic conformed to the first-order kinetic equation,and the half-life was 69.3 h.In the prevention and control of Blepharipa Tibialis Chao,the medication timing should be guaranteed.
