摘要
目的检测铁路客运站车德国小蠊对常用杀虫剂的抗药性,为铁路站车德国小蠊的防制提供依据。方法采用WHO推荐的药膜法,将德国小蠊分别放入用杀虫剂制作的广口药膜瓶中,观察击倒率,计算抗性系数。结果铁路站车德国小蠊对溴氰菊酯、高效氯氰菊酯、氯氰菊酯、氯菊酯、功夫菊酯、敌敌畏、残杀威、毒死蜱、仲丁威的抗性系数分别为143.96～171.49、10.25～118.18、18.58～135.08、18.14～34.31、4.08～5.11、1.91～2.50、2.13～2.45、1.20～1.65、1.48～3.62。结论德国小蠊已对溴氰菊酯、高效氯氰菊酯、氯氰菊酯、氯菊酯、功夫菊酯产生不同程度的抗性,铁路站车德国小蠊的防控应根据其抗性水平选择适合药物。
Objective station and provide a basis for the control of B. germanica in passenger train and station. Methods The residual film method recommended by WHO was used to measure the resistance of B. germanica to commonly used insecticides. B. germanica was placed in the jars with residual films; the knockdown rates and resistance ratios were calculated. Results The resistance ratios of B. germanica were 143.96-171.49 for deltamethrin, 10.25-118.18 for beta cypermethrin, 18.58-135.08 for cypermethrin, 18.14-34.31 for permethrin, 4.08-5.11 for lambda cyhalothrin, 1.91-2.50 for dichlorvos, 2.13-2.45 for propoxur, 1.20-1.65 for chlorpyrifos, and 1.48-3.62 for fenobucarb, respectively. Conclusion B. germanica has developed different levels of resistance to deltamethrin, beta cypermethrin, cypermethrin, permethrin, and lambda cyhalothrin, so the most suitable insecticide should be selected according to the resistance levels to effectively control B. germanica in passenger train and station.
