摘要： 为掌握玉溪十字花科蔬菜桃蚜对常用杀虫剂的抗性和分布特征，针对桃蚜已产生抗性的问题进行室内毒力测定。采用室内生物测定方法，检测玉溪4 个田间种群和1 个自然保护区敏感种群对6 种常用杀虫剂的敏感性，得出田间种群抗性水平。结果表明，通海种群最高，处于敏感至极高抗水平（0.64~409.52 倍）；元江种群处于敏感至极高抗水平（0.19~317.55 倍）；澄江种群处于敏感至高抗水平（0.59~77.71 倍）；红塔区种群抗性水平最低，处于敏感至敏感下降水平（0.38~4.79 倍）。6 种药剂的抗性为：抗蚜威（4.79~409.52 倍）＞溴氰菊酯（4.27~80.22 倍）＞毒死蜱（1.97~13.95 倍）＞吡虫啉（0.93~5.74 倍）＞吡蚜酮（1.25~3.49 倍）＞阿维菌素（0.19~0.64 倍）。玉溪菜区4 个种群，除红塔区种群外，均对抗蚜威、溴氰菊酯、毒死蜱3 个药剂产生了不同程度的抗性；防治过程中应停止使用抗蚜威、溴氰菊酯，适当使用毒死蜱，吡蚜酮、吡虫啉和阿维菌素轮换使用。

Abstract: The study aims to master the present resistance characteristics of Myzus persicae (Sulzer) populations to common insecticides and the resistance distribution of the medicament in Yunxi City. The author used the indoor bioassay methods, tested 6 kinds of common insecticides on 4 field populations and 1 nature reserve sensitive population, and obtained the resistant levels of the field populations. The results showed that Tonghai population had the highest sensitivity, which was from sensitive to extremely high levels (0.64-409.52 times); Yuanjiang population was from sensitive to extremely high levels (0.19-317.55 times); Chengjiang population was from sensitive to the high levels (0.59-77.71 times); Hongta District population had the lowest levels, which was from sensitive to sensitive falling levels (0.38-4.79 times). Resistance to 6 drugs was in an order as: pirimicarb (4.79- 409.52 times) > deltamethrin (4.27- 80.22 times) > chlorpyrifos (1.97- 13.95 times) > imidacloprid (0.93-5.74 times)> pymetrozine (1.25-3.49 times)> abamectin (0.19-0.64 times). Among the 4 populations in Yuxi, except the Hongta District population, the other three were all resistant to pirimicarb, deltamethrin and chlorpyrifos. In the prevention and control of vegetable Myzus persicae (Sulzer), chlorpyrifos, abamectin, pymetrozine and imidacloprid should be applied in turn with appropriate levels, and the use of pirimicarb and deltamethrin should be stopped.
