摘　　要：目的了解国际航行船舶携带的德国小蠊抗药性情况,为口岸防治合理用药提供科学依据。方法采集国际航行船舶上孳生的德国小蠊自然种群,带回实验室繁育,培养1代后,取2～3周龄雄性成虫,用药膜接触法测定其对丙烯菊酯、溴氰菊酯、敌敌畏、仲丁威、残杀威、毒死蜱、高效氯氰菊酯7种杀虫剂的抗性倍数。结果采自3艘国际航行船舶的德国小蠊对7种杀虫剂的抗性依次为2.54～5.56、2.18～5.14、3.98～5.87、1.57～1.91、0.83～1.27、1.06～1.59、2.89～3.93倍。结论 3艘国际航行船舶携带的德国小蠊对菊酯类及有机磷类杀虫剂敌敌畏已产生耐药性或抗药性,对氨基甲酸酯类杀虫剂及毒死蜱较为敏感,口岸防治德国小蠊可采用氨基甲酸酯类杀虫剂。Objective To evaluate the insecticide resistance of Blattella germanica collected from international voyage ships. Methods B. germanicas were collected from international voyage ships and bred in laboratory, male insects of the first offspring aged 2-3 weeks were collected to evaluate their resistance to allethrin, deltamethrin, DDVP, fenobucarb, propoxur, chlorpyrifos, and decamethrim. The resistance was determined by the insecticide film contact method. Results The resistance level of B. germanica from three ships against allethrin, deltamethrin, DDVP, fenobucarb, propoxur, chlorpyrifos, and decamethrim was 2.54-5.56, 2.18-5.14, 3.98-5.87, 1.57-1.91, 0.83-1.27, 1.06-1.59 and 2.89-3.93 times of the susceptible strain, respectively. Conclusion The B. germanica from the three ships have developed different degrees of resistance to pyrethroid insecticides and DDVP, but still susceptible to carbamate insecticides and chlorpyrifos. The carbamate insecticides can be used for controlling cockroaches in ports.
