摘要
[目的]明确10%溴虫氟苯双酰胺悬浮剂对黑刺粉虱和小贯小绿叶蝉的防治效果。[方法]采用喷雾法进行了田间药效试验。[结果]10%溴虫氟苯双酰胺悬浮剂对2种茶园害虫防治效果良好,30、40、50 mg/kg处理药后14 d对黑刺粉虱和小贯小绿叶蝉的防效分别为87.25%~90.80%、83.63%~88.84%,显著优于对照药剂25 g/L联苯菊酯EC40 mg/kg处理(防效分别为83.61%、79.37%)。[结论]10%溴虫氟苯双酰胺悬浮剂是防治黑刺粉虱、小贯小绿叶蝉的理想药剂,推荐使用剂量为30~50 mg/kg。
[Aims] The study aims to evaluate the field efficacy of broflanilide 10% SC against Aleurocanthus spiniferus and Empoasca onukii. [Methods] The field trials were carried out by routine spraying method. [Results] The results showed that the control efficacy of broflanilide 10% SC against A. spiniferus and E. onukii at 30, 40 and 50 mg/kg was87.25-90.80% and 83.63-88.84% respectively at 14 th d after treatment, which performed better control effect than bifenthrin 25 g/L EC at 40 mg/kg（control efficacy of 83.61 and 79.37%, respectively）. [Conclusions] Broflanilide was an ideal agent to control A. spiniferus and E. onukii, the recommended usage in fields was 30-50 mg/kg.
