摘　　要：[Objective] The aim was to select insecticides effective in contrlling Pseudaulacaspis pentagona Infecting Pitaya. [Method] Efficacy effects of 11 insecticides in 22 concentrations were performed on Pseudaulacaspis pentagona Infecting Pitaya. [Result] When the insecticides were sprayed after 14 d, the treatment group with 22.4% spirotetramat SC at two concentrations proved the best, with control effects at 95.24% and 92.05%, followed by Nurelle at two concentrations, with control effects at 90.86% and 89.19%, and the control effects of chlorpyrifos （x2 000） was the poorest at only 67.08%. Therefore, it is feasible to make use of 22.4% spirotetramat SC, chlorpyrifos EC and Nurelle EC alternatively in controlling Pseudaulacaspis pentagona in case of pesticide resistance. [Conclusion] The research provided references for scientific use of insecticides in controlling Pseudaulacaspis pentagona Infecting Pitaya.[目的]筛选防治火龙果桑白蚧有效的杀虫剂。[方法]以11种不同类型的杀虫剂、22种浓度处理对火龙果桑白蚧进行了田间药效试验。[结果]药后14 d,22.4%螺虫乙酯SC 4 000倍液的防治效果最好,为95.24%,其次是22.4%螺虫乙酯SC 5 000倍液和农地乐EC1000倍液防效较好,防治效果分别为92.05%和90.86%,毒死蜱EC 2 000倍液防治效果较差,只有67.08%。在生产中防治火龙果桑白蚧,建议用22.4%螺虫乙酯SC 4 000倍液、5 000倍液和农地乐EC 1 000倍液交替使用。[结论]该研究为果农防治桑白蚧科学合理用药提供了参考。
