目的了解家庭农场主要病媒生物孳生侵害情况,探究家庭农场病媒生物防治方法和策略。方法分别采用夹夜法、人工小时法、笼诱法进行鼠、蚊、蝇密度监测,目测法调查鼠、蚊、蝇孳生侵害情况,并开展蚊虫携带病原体的检测。结果家庭农场平均鼠密度为4.29只/百夹、鼠征阳性率为19.74%、防鼠设施不合格率为65.30%,平均蚊密度为40.27只/人工小时、蚊幼阳性率为11.95%,平均蝇密度为2.93只/笼、蝇幼阳性率为13.35%,均远高于上海市地方标准的规定;其中一个家庭农场送检的三带喙库蚊检出乙脑病毒阳性。结论家庭农场的鼠、蚊、蝇孳生侵害情况严重,应当积极开展病媒生物防治工作,主要采取药物控制、孳生环境清理与加强防治设施等方法。
Objective To understand the major vector-borne diseases in family farms and to explore the methods and strategies of prevention and control of vector-borne diseases in family farms. Methods The method of catgut - night, artificial - hour and cages were used to monitor the density of rats, mosquitoes and flies respectively. The damage of rats, mosquitoes and flies was investigated by visual inspection and the detection of mosquito - borne pathogens was carried out. Results The average rodent densities of family farms were 4.29 / 100 clones. The positive rate of rodents was 19.74%. The unqualified rate of rodent control facilities was 65.30%. The average mosquito density was 40.27 / artificial hour. The positive rate of mosquito was 11.95% The density of flies was 2.93 / cage, the positive rate of fly was 13.35%, which was much higher than that of local standards in Shanghai. One of the three farms in our family farms tested positive for JEV. Conclusion The infestation of mice, mosquitoes and flies in family farms is serious. Biological vector control should be actively carried out. The main methods are drug control, breeding environment and strengthening prevention and control facilities.
