Abstract：The results of laboratory toxicity test showed that combination of pyrifluquinazon and acetamiprid had synergistic effect on control of tobacco aphids. The synergies of pyrifluquinazon and acetamiprid were the most obvious in the ratio of against tobacco aphids.In field test， 3 days after treatment，the control effect of effective component concentration of 0.100g/L pyrifluquinazon + acetamiprid treatment was significantly higher than that of effective component concentration of 0.050g/L pyrifluquinazon， 0.050g/L acetamiprid and 0.067g/L pyrifluquinazon treatments. After 7 days of treatment，the effective component concentration of 0.067g/L single pyrifluquinazon treatment and the effective component concentration of 0.100 （204号 g/L pyrifluquinazon + acetamiprid treatment were significantly higher than other treatments. After l4 days of treatment，the efficacy of treatment with the effective component concentration of 0.100g/L pyrifluquinazon + acetamiprid treatment was higher than that of other treatments. The results showed that the treatment of pyrifluquinazon + acetamiprid can effectively control the harm of aphids in tobacco fields. It is recommended to use the effective ingredient of （202 0.100g/L pyrifluquinazon + acetamiprid to control aphids in tobacco fields.
