南通市流行性乙型脑炎蚊媒抗性及其防治对策研究

Resistance of mosquito-borne Japanese encephalitis and its control countermeasure in Nantong city

目的对乙脑蚊媒进行抗性检测,为合理使用杀虫剂提供科学依据,有效做好灭蚊工作,降低蚊虫密度,切断传播途径,减少人群感染机会。方法采用区分剂量法。结果采用相对敏感药物对重点区域进行滞留喷洒,杀灭效果明显,能快速降低蚊虫密度。结论经过长期的化学防治,蚊虫对一些杀虫剂产生了明显的抗性;准确地对流行性乙型脑炎蚊媒抗性及其防治进行分析,提出了有效的防治策略。

Objective To provide scientific basis for using insecticide, the resistance of mosquito-borne Japanese encephalitis was tested. In this way it could reduce the mosquito density, cut off the transmission and reduce the chances of crowd infection. Methods Distinguishing dosage method. Results Spraying relatively sensitive insecticides in key areas could have good effect and reduce the mosquito density quickly. Conclusion After a long- term chemical control, mosquito have had resistance to insecticide ;analysing the resistance of mosquito - borne Japanese encephalitis can provide control strategies and improve the control effect.
