Abstract: Objective To investigate the quantity, distribution, and occurrence dynamics of important vectors by emergency monitoring of vectors after flood in Jintang county of Sichuan province, China, and to provide a scientific basis for preventing and controlling the outbreak and prevalence of vector-borne infectious diseases after flood. Methods On July 12, 2018, the first day after flood, the densities of flies and rodents were observed in the flooded areas of Jintang county. A mosquito lamp was used to observe the density of mosquitoes, and the rodent trace method was used to observe the density of rodents. Results Mosquitoes and flies were the key vectors for biological control. After sterilization, the mean density of mosquitoes was 1.78 mosquitoes/lamp·hour, the density of flies decreased from 29.30 flies/m2 to 6.44 flies/m2, and the mean density of rodents was 0.66 places/km. Environmental health was restored and the breeding sites of mosquitoes and files were effectively controlled. Conclusion By summarizing and analyzing the data of vector monitoring after flood, we can first clean up the important breeding garbage and carry out accurate insecticidal control to guide prevention and control, so as to effectively prevent and control the outbreak and prevalence of vector-borne infectious diseases.

摘要: 目的 通过对金堂县洪灾后病媒生物的应急监测,掌握重要病媒生物数量、分布及发生动态,为洪灾后预防和控制病媒生物传染病的暴发与流行提供科学依据。方法 2018年7月12日(洪灾后第1天)对四川省金堂县采用目测法监测成蝇密度,诱蚊灯法调查受灾区的蚊密度,鼠迹法测定鼠密度。结果 蚊和蝇是本次病媒生物防控的重点对象,消杀后平均蚊密度为1.78只/(灯·h),蝇密度从高峰时的29.30只/m2下降到6.44只/m2,平均鼠密度为0.66处/km。环境卫生得到恢复,蚊、蝇孳生地得到有效治理。结论通过总结分析洪灾过后病媒生物监测数据,采取重要孳生垃圾优先清理并进行精准杀虫的方式指导防制工作,可有效地预防与控制病媒传染病的暴发和流行。
