摘　　要：试验结果表明,33%高效氯氟氰菊脂·吡虫啉SC对甘蔗绵蚜虫有很好的防治效果,参试的3个剂量375 g/hm^2(a.i.123.8 g/hm^2)、300 g/hm^2(a.i.99.0 g/hm^2)、250 g/hm^2(a.i.85.5 g/hm^2)在药后7天的防效均在99.7%以上。推荐使用剂量为250 g/hm^2(a.i.85.5 g/hm^2)和300 g/hm^2(a.i.99.0 g/hm^2)。Field tests revealed that lambda-cyhalothrin·Imidacloprid 33%SC had good effect on controlling sugarcane aphids.All 3 application rate,i.e.375 g/hm2(a.i.123.8 g/hm2),300 g/hm2(a.i.99.0 g/hm2),250 g/hm2(a.i.85.5 g/hm2),showed control effects higher than 99.7%7 days after application.Recommended application rates are 250 g/hm2(a.i.85.5 g/hm2)and 300 g/hm2(a.i.99.0 g/hm2).
