摘　　要：目的分析江苏省无锡市近10年来德国小蠊对常用杀虫剂的抗药性发展趋势。方法 2010-2018年间,每隔1年选取无锡市的农贸市场、饭店和食品城,使用电动吸蟑器法和蜚蠊诱捕器法采集德国小蠊,带回实验室饲养一代后,采用药膜法测定抗药性水平。结果 2010-2018年德国小蠊对高效氯氰菊酯的抗性倍数分别为8.25、9.94、5.78、12.39和6.06倍;对溴氰菊酯的抗性倍数分别为14.02、6.27、16.75和10.79倍;对残杀威的抗性倍数分别为1.75、1.48、1.32、2.53和1.24倍;对乙酰甲胺磷的抗性倍数分别为2.14、1.31、1.01、1.03和0.76倍;2014-2018年对毒死蜱的抗性倍数分别为0.91、2.09和0.39。结论 2010-2018年间,无锡市德国小蠊对高效氯氰菊酯和溴氰菊酯的抗性水平不断增长,呈中度至高度抗性;对残杀威、乙酰甲胺磷和毒死蜱的抗性水平呈现缓慢下降趋势,总体呈敏感至低度抗性。Objective To analyze the resistance of Blattella germanica to commonly used insecticides in Wuxi, Jiangsu province, China in the past 10 years. Methods Every two years from 2010 to 2018, B. germanica was captured by electric suction device and mechanic trapping devices in farmer’s markets, restaurants, and food trading centers in Wuxi.Captured cockroaches were brought back to the laboratory, reared for one generation, and insecticide resistance was measured by the residual film method. Results The resistance ratio(RR) of B. germanica to beta-cypermethrin was8.25(2010), 9.94(2012), 5.78(2014), 12.39(2016), and 6.06(2018). The RR to deltamethrin was 14.02(2012), 6.27(2014), 16.75(2016), and 10.79(2018). The RR to propoxur was 1.75(2010), 1.48(2012), 1.32(2014), 2.53(2016), and1.24(2018). The RR to acephate was 2.14(2010), 1.31(2012), 1.01(2014), 1.03(2016), and 0.76(2018). The RR to chlorpyrifos was 0.91(2014), 2.09(2016), and 0.39(2018). Conclusion The resistance of B. germanica to betacypermethrin and deltamethrin increased from 2010 to 2018 in Wuxi, with medium to high levels of resistance;the resistance to propoxur, acephate, and chlorpyrifos decreased slowly and showed overall sensitive to low levels of resistance.
