Abstract: Objective To investigate the insecticide resistance level of Blattella germanica to commonly used insecticides in Zhejiang province of China, and to provide basic data for rational use of insecticides and scientific control of cockroaches. Methods In 2018, the residual film method was used to determine the resistance level of B. germanica to pyrethroids (beta-cypermethrin and deltamethrin), organophosphate pesticides (acephate and dichlorvos), and carbamates (propoxur) in 11 prefecture-level cities of Zhejiang province. Results The analysis of the resistance level of B. germanica to beta-cypermethrin showed that B. germanica was sensitive in Shaoxing and Ningbo cities and had low resistance in Taizhou, Hangzhou, Zhoushan, Huzhou, Quzhou, and Jiaxing cities, moderate resistance in Jinhua and Lishui cities, and high resistance in Wenzhou city (R/S=16.00). As for deltamethrin, B. germanica was sensitive in Shaoxing and had low resistance in Ningbo, Huzhou, Hangzhou, Taizhou, Quzhou, Zhoushan and Jiaxing, moderate resistance in Wenzhou and Lishui, and high resistance in Jinhua (R/S=11.66). As for acephate, B. germanica was sensitive in Shaoxing, Huzhou, Jinhua, and Hangzhou and had low resistance in the other cities. As for dichlorvos, B. germanica was sensitive in Shaoxing, Huzhou, and Taizhou and had low resistance in Jinhua, Ningbo, Hangzhou, Quzhou, Wenzhou, Zhoushan, and Jiaxing. As for propoxur, B. germanica was sensitive in Huzhou, Hangzhou, Ningbo, Zhoushan, and Jinhua and had low resistance in the other cities. Conclusion Varying level of resistance of B. germanica to the above 5 insecticides are observed in 11 prefecture-level cities of Zhejiang province, with a relatively high level of resistance to pyrethroids and with sensitivity or low resistance to acephate, dichlorvos, and propoxur. Therefore, scientific and rational selection and use of insecticides is recommended to control cockroach and delay the development of resistance.

摘要: 目的 掌握浙江省德国小蠊对常用杀虫剂的抗药性水平,为合理用药及科学防制提供基础数据。方法 2018年,浙江省11个地级市采用药膜法测定德国小蠊对拟除虫菊酯类(高效氯氰菊酯和溴氰菊酯)、有机磷类(乙酰甲胺磷和敌敌畏)、氨基甲酸酯类(残杀威)的抗药性水平。结果 德国小蠊对高效氯氰菊酯抗性结果:绍兴和宁波市种群呈敏感;台州、杭州、舟山、湖州、衢州和嘉兴市种群为低度抗性;金华和丽水市种群为中度抗性;温州市种群达高度抗性[抗性倍数(R/S)=16.00]。对溴氰菊酯抗性结果:绍兴市种群呈敏感;宁波、湖州、杭州、台州、衢州、舟山和嘉兴市种群为低度抗性;温州和丽水市种群为中度抗性;金华市种群达高度抗性(R/S=11.66)。对乙酰甲胺磷抗性结果:绍兴、湖州、金华和杭州市种群呈敏感,其余地市种群均为低度抗性。对敌敌畏抗性结果:绍兴、湖州和台州市种群呈敏感;金华、宁波、杭州、衢州、温州、舟山和嘉兴市种群为低度抗性。对残杀威抗性结果:湖州、杭州、宁波、舟山和金华市种群呈敏感,其余地市种群均为低度抗性。结论 浙江省11个地市德国小蠊对5种杀虫剂产生了不同程度的抗药性,对拟除虫菊酯类杀虫剂抗药性处于较高水平,对乙酰甲胺磷、敌敌畏和残杀威处于敏感或低抗,建议科学、合理选择用药控制蜚蠊,延缓抗性发展。
