摘　　要：目的 掌握山东省不同地区淡色库蚊对常用化学杀虫剂的抗性状况,为制定防治对策提供依据。 方法 采用WHO生物测定法。 结果 全省部分地区现场淡色库蚊对所测杀虫剂均产生了不同程度的抗药性,其抗性指数以氯氰菊酯最高,达135.48倍,其次为溴氰氰菊酯、DDVP、DDT;不同地区淡色库蚊对不同的杀虫剂的抗性也有较大差异且在连续几年调查中均呈逐年增高趋势。 结论 应加强蚊虫抗药性监测,并根据具体情况,采用适宜防蚊方法,合理的使用杀虫剂,预防或减缓淡色库蚊对杀虫剂抗性的产生和发展。Objective To determine the status of resistance of Culex pipiens pollens to several commonly used insecticides in Shandong Province for controlling the occurrence and development of resistance. Method WHO standard bioassay was employed to calculate LC50 and resistance index. Results Resistance of Culex pipiens pollens collected from all fields increased in different degrees. The highest resistance index to Cypermethrin is 135.48,followed by those of against Deltamethrin,DDVP and DDT. Significant differences of resistance to applied insecticides in differrnt areas were observed and the resistance tends to be higher according to the results of the investigations lasted for several years. Conclusion Resistance should be monitored regularly. Integrated use of insecticides and other methods for control of Culex pipiens pallens should be carried out according to local conditions. The occurrence and development of resistance could be prevented and reduced by scientific and rational use of insecticides.
