目的了解病媒生物种群、密度分布及季节消长规律,为制定防制措施提供依据。方法 2013年采用夜夹法监测鼠密度,用诱蚊灯法监测蚊密度,用笼诱法监测蝇类,用蟑螂屋诱捕法监测蟑螂,记录并统计监测结果。结果盐城市盐都区全年鼠密度为0.41%,褐家鼠为优势鼠种(占70.00%),3月鼠密度最高,为0.99%。4—11月蚊虫活动期间,蚊密度为0.559只/人工小时,淡色库蚊为优势蚊种(占47.9%),6—8月为蚊密度高峰期,占捕蚊总数的76.63%。4—11月蝇活动期间,蝇密度为8.15只/笼,家蝇为优势蝇种(占52.15%),5—8月为蝇密度高峰期,占捕蝇总数的90.80%。全年均未捕获到蟑螂。结论经常开展卫生宣传,搞好环境治理,消除孳生地,是消灭“四害”工作的重点。
Objective To understand the population, density distribution and seasonal fluctuation of vectors and provide the basis for the development of control measures. Methods In 2013, the density of mice was monitored by night clamp method. The mosquito density was monitored by mosquito lamp method. The flies were monitored by cage induction method. The cockroaches were monitored by the cockroach trap method. The monitoring results were recorded and statistically analyzed. Results The annual rat density was 0.41% in Yandu District of Yancheng City. The dominant species was Rattus norvegicus (70.00%), and the highest density was 0.99% in March. From April to November, mosquito density was 0.559 mosquito / artificial hour, Culex pipiens pallens dominant mosquito species (47.9%), mosquito density peak from June to August, accounting for 76.63% of mosquitoes total. From April to November, the flies density was 8.15 / cage, housefly dominant flies species (52.15%) and flies density peak from May to August, accounting for 90.80% of the total number of flies. Cockroaches were not caught throughout the year. Conclusions Often carrying out publicity on health, doing a good job in environmental governance and eliminating breeding places are the focuses of eliminating the “four pests” work.
