To understand the current status of insecticide resistance of the invasive western flower thrips, Frankliniella occidentalis, in China, the responses of six field populations to six commonly used insecticides, i.e. spinosad, spinetoram, cyantraniliprole, imidacloprid, acetamiprid and pyriproxyfen, were evaluated in comparison with a susceptible laboratory strain.
Field populations tended to be less susceptible than the laboratory strain. The population from Shouguang, Shandong Province, showed the lowest levels of susceptibility. A 15.64-fold and 17.29-fold resistance to spinosad and spinetoram was detected in the Shouguang population. A 11.74-fold and 13.64-fold resistance to cyantraniliprole was detected in populations from Daxing in the Beijing area and Shouguang. All populations showed a low level of resistance to imidacloprid, acetamiprid and pyriproxyfen, except for the Shouguang population, which was 127.58-fold more resistant to pyriproxyfen.
Variations in resistance to the tested insecticides were observed among the sampled population. Spinosad and spinetoram were the most efficient insecticides and are recommended for use in an integrated management programme. Resistance management strategies should be implemented to reduce the potential for resistance evolving. © 2015 Society of Chemical Industry.
为了解入侵害虫西花蓟马Frankliniella occidentalis在中国的抗药性现状，将6个田间种群对6种常用杀虫剂（多杀菌素、乙基多杀菌素、氰虫酰胺、吡虫啉、啶虫脒和吡丙醚）的反应与一个敏感的实验室品系进行比较评估。
田间种群的敏感性往往低于实验室品系。山东省寿光的种群敏感性最低。在寿光种群中检测到对多杀菌素和乙基多杀菌素的抗性分别为15.64倍和17.29倍。在北京地区大兴和寿光的种群中检测到对氰虫酰胺的抗性分别为11.74倍和13.64倍。除寿光种群对吡丙醚的抗性为127.58倍外，所有种群对吡虫啉、啶虫脒和吡丙醚的抗性水平都较低。
在抽样种群中观察到对所测试杀虫剂的抗性存在差异。多杀菌素和乙基多杀菌素是最有效的杀虫剂，建议用于综合管理方案。应实施抗性管理策略以降低抗性发展的可能性。© 2015化学工业协会。
