目的对辽源地区病媒生物(蝇)的抗药性及其机制进行试验研究,为科学指导本市媒介生物防治工作,控制传染病的暴发流行提供科学依据。方法采用点滴法,即国际上规定的标准测定方法,将一定量的药液直接滴在昆虫体壁上。结果家蝇对溴氰菊酯、敌敌畏、氯氰菊酯、二氯苯醚菊酯抗药性测定结果显示,辽源地区家蝇对有机磷和拟除虫菊酯类杀虫剂不仅产生了单一抗性,还产生多种抗药性和交互抗性;对敌敌畏的抗性为高抗水平。结论辽源地区病媒生物对有机磷和拟除虫菊酯类杀虫剂已产生不同程度的抗药性,极大地影响病媒生物防治效果。首先要治理环境,清除积水杂物,减少病媒生物孳生场所;然后根据不同时期、不同地点、针对不同病媒生物采用不同的防治方法或联合应用几种方法,取长补短,以期达到较好的防治效果。
Objective To study the drug resistance and its mechanism of vectors (flies) in Liaoyuan area, and to provide a scientific basis for scientifically guiding the prevention and control of vector organisms in this Municipality and controlling the outbreak of infectious diseases. Methods Using the drip method, which is the international standard test method, a certain amount of liquid drops directly on the insect body wall. Results The resistance test of housefly to deltamethrin, dichlorvos, cypermethrin and permethrin showed that housefly in Liaoyuan not only had single resistance to organophosphate and pyrethroid insecticides, but also produced more Resistance and cross resistance; resistance to dichlorvos was highly resistant. Conclusion The vector organisms in Liaoyuan have different levels of resistance to organophosphorus and pyrethroid insecticides, greatly affecting the vector control effect. First of all, to control the environment, remove water debris and reduce vector breeding sites; and then according to different periods, different locations, for different vectors using different control methods or a combination of several methods, learn from each other in order to achieve better Control effect.
