为寻找防治褐飞虱的高效、低毒药剂，2012年对六(3)代褐飞虱进行了不同药剂处理的防治试验。结果表明：9.7%乙虫腈SC 1200 g/hm2对褐飞虱具有较好的速效性和持效性，药后1～21 d的防效为80.13%～94.07%；25%吡蚜酮SC 450 g/hm2的速效性稍差，但持效性与9.7%乙虫腈SC 1200 g/hm2处理相当，药后7～21 d的防效为89.60%～94.04%。

In order to find high-efficient, low-toxic insecticides for controlling brown plant hopper, the field effect trials on the 6th (3) generation brown plant hopper with different pesticides were carried out in 2012. The results showed that ethiprole 9.7%SC 1 200 g/hm2 had good quick-acting and persistence efficacy on brown plant hopper, the control effects were 80.13%-94.07%within 1-21 days after spraying. Pymetrozine 25%SC 450 g/hm2 had poor quick-acting efficacy, but its persistence efficacy was the same as ethiprole 9.7%SC 1 200 g/hm2, and its control efficacies within 7-21 days after spraying were 89.60%-94.04%.
