2009年深圳市龙岗区蚊类监测报告

Mosquito surveillance and control strategy in Longgang district,Shenzhen in 2009

目的对龙岗区蚊虫种群和密度进行监测,为深圳大运会期间有效控制蚊媒传播疾病奠定基础。方法 2009年3-12月,在龙岗区10个街道中,每月中旬布放诱蚊灯,对医院、绿化地和居民区等环境进行成蚊密度监测。结果龙岗区10个街道共布放诱蚊灯98个,诱蚊诱卵器600个,入户调查369户,检测室内外容器730个,监测到3属6种1082只成蚊,平均成蚊密度为1.4只/h。其中,致倦库蚊为优势蚊种(71.3%),容器指数为25.8,布雷图指数达50.7。结论龙岗区蚊虫密度及布雷图指数大大超过国家标准,提示有蚊媒传播疾病如登革热、乙型脑炎等流行的可能。

Objective To provide scientific evidence for prevention and control program on mosquito-borne disease through monitoring mosquito species and density in Longgang district, Shenzhen. Method During March to December, 2009,mosquito-traps were set in hospitals, greenbelt and residential areas in third week of each month. Results We had set 98 mosquito-traps,720 ovi-traps during the monitoring period.Three hundred and sixty-nine households were surveyed,and 730 containers were examined. The average mosquito density was 1.4 mosquitoes per hour. Culex pipiens fatiganss was the dominant species, accounting for 71.3%,with Breteau index soared at 50.7.
