于室内和田间测定了5%高氯?啶虫脒热雾剂对烟粉虱的杀虫活性。结果表明：5%高氯?啶虫脒热雾剂对烟粉虱成虫具有很强的毒杀作用,其毒力回归方程为4.0078＋1.4577x, LC50值为4.79 mg/L,说明氯氰菊酯对啶虫脒具有显著的增效作用,其共毒系数(CTC)为186；田间防治试验显示,5%高氯?啶虫脒热雾剂对烟粉虱具有明显的控制作用,在处理剂量为37.5～112.5 g/hm2时,药后7 d的防治效果可达75%以上。5%高氯?啶虫脒热雾剂可作为防治烟粉虱的专用药剂。

Insecticidal activity of 5% beta-cypermethrin and acetamiprid hot fogging concentrate against Bemisia tabaci were investigated in the laboratory and field. The results showed that the preparation has high toxicity against the adult of B. tabaci with linear regress equation of 4.007 8+1.457 7x and LC50 of 4.79 mg/mL, which displayed that beta-cypermethrin exhibited strong synergistic effect on acetamiprid, the co-toxicity coefficient (CTC) being as high as 186. In dealing with a dose of 2.5 to 7.5 g/667 m2, he corrected efficacy can reach more than 75% when examined at 7th day after treatment. 5%beta-cypermethrin and acetamiprid hot fogging concentrate as a insecticide controlling B. tabaci is therefore promising.
