2012—2013年深圳市龙岗中心城区病媒生物监测结果

Monitoring results of vectors in Longgang central urban area of Shenzhen City from 2012-2013

目的了解深圳市龙岗中心城区病媒生物的种群和密度,建立病媒传染病的预警体系。方法 2012—2013年在龙岗中心城区选取居民区、医院、公园、工地、餐饮、酒店/旅馆、农贸市场及其周边作为监测点,分别监测蚊、蜚蠊、蝇、鼠等病媒生物。结果龙岗中心城区蚊密度为7.9只/灯,不同监测点蚊密度为公园>工地>医院>居民区,致倦库蚊为优势蚊种,平均布雷图指数为14,蜚蠊密度为2.3只/盒,德国小蠊为优势种;蝇密度为2.35只/笼,家蝇为优势种;鼠密度为3.9%,褐家鼠为优势种。结论结果表明,该地区造成登革热的流行,及时掌握病媒生物的种群及其密度对相应的病媒传染病的防治和疫情处理非常必要,在今后工作中应继续开展长期监测,制定切实可行的预防措施。

[Objective]To understand the biological species and density of vectors in Longgang central urban area of Shenzhen City,establish a vector-borne infectious disease early warning system. [Methods]During 2012-2013,the investigation was performed in the monitoring points of residential area,hospital,park,construction site,restaurant,hotel,farmer＇s market and its surrounding area in Longgang central urban area of Shenzhen City. The monitoring vectors included mosquito,cockroach,fly and mouse.[Results]In the Longgang central urban area,the mosquito density was 7. 9 /lamp,and the mosquito density in the park was the highest,followed by construction site,hospital and residential area. Culex quinquefasciatus was the dominant species,and Breteau index was 14. The cockroach density was 2. 3 / box,and Blattella germanica was the dominant species. The fly density was2. 35 / cage,and Musca domestica was the dominant species. The mouse density was 3. 9%,with the dominant species of Rattus norvegicus. [Conclusion]It is necessary to rapidly understand the biological species and density of vectors to prevent and control the corresponding vector-borne infectious disease. Meanwhile,it is important to continue to carry out long-term monitoring in future,and formulate the feasible preventive measures.
