| 摘 要： | 目的观察鼠疫疫源地印鼠客蚤对杀虫剂的抗药性变化。方法药膜法。结果鼠疫疫源地印鼠客蚤对灭蚤药物的敏感性有所下降，但强化灭蚤地区印鼠客蚤对氯菊酯、溴氰菊酯、马拉硫磷、敌敌畏、残杀威、奋斗呐的敏感性大幅度下降，其比。分别是0．0165、0．1170、0．0202、0．0002、0．0038、0．0087mg／cm^2，分别是对照区的4．78、16．32、2．08、1．70、1．66和2．94倍。结论大量而持续地使用杀虫剂可产生抗药性，因此要加强对蚤类抗药性监测，轮换使用灭蚤药物，科学、合理用药。

| Abstract: | Objective To study the resistant change of Xenopsylla cheopis to insecticides in plague natural focus. Methods Surface contact method was used in this study. Results The LC40 of X. cheopis to malathion, propoxur, dichlorovos, permethrin, deltamethrin and fendona in the constant flea-killing areas were 0. 0165, 0. 1170, 0. 0202, 0. 0002, 0. 0038, 0. 0087 mg/cm2, which were 4.78, 16.32, 2.08, 1.70, 1.66 and 2.94 times of the control. Conclusion Large and constant use of flea-insecticide may lead to resistance. Therefore, the resistance of insecticide must be monitored constantly when killing fleas. The insecticide must be used scientifically and rationally. |
