开展对德国小蠊等重要病媒生物抗性的监测,掌握其对常用杀虫剂的抗性水平,了解其抗性动态,对在防治工作中合理选择和使用化学杀虫剂,提高防治效果,延缓抗药性的发生和发展具有十分重要的意义。因此,2011年对银川市的德国小蠊抗药性进行了调查,结果报告如下。1材料与方法1.1供试昆虫德国小蠊成若虫采自银川市某宾馆,带回实验室正常饲养,培养一代后取2～3周健康、活跃的雄性成虫供试。1.2供试药剂96%敌敌畏、91.8%残杀威、96%功夫菊酯、
Carry out the monitoring of the important vector resistance of Blattella germanica and other important vectors, master the level of resistance to commonly used insecticides, understand its resistance dynamics, and select and use chemical pesticides in the prevention and control work to improve the control effect , Delay the occurrence and development of drug resistance is of great significance. Therefore, in 2011, the resistance of Blattella germanica in Yinchuan was investigated and the results are reported as follows. 1 Materials and methods 1.1 Test insects Blattella germanica collected from a hotel in Yinchuan City, back to the normal laboratory culture, take a generation after 2 to 3 weeks to take healthy and active male adult test. 1.2 for the test drug 96% dichlorvos, 91.8% to kill Granville, 96% cyhalothrin,
