全市埃及伊蚊分布在4个公社及市区西片,面积较广,属登革热流行的“危险区域”。为进一步探索消灭和控制埃及伊蚊的办法,1982年在地角村,高德公社的马屋村、李屋村,外沙公社的岭底村,进行饮用水缸养鱼防制埃及伊蚊的现场观察。防制方法:放养鱼前对观察点的所有住户贮水缸逐个进行检查有无埃及伊蚊幼虫,并造册登记,每只贮水缸放养1～2尾(尼罗罗非鱼或胡子鲶),定期由专人对所有水缸进行检查,登记(每月3次以上)。以房屋指数、布雷图指数作依据,对比放养鱼前后埃及伊蚊幼虫的密度变化。房屋指数
The city of Egypt Aedes mosquitoes distributed in four communes and urban films, a wider area, is a popular dengue “dangerous area.” In order to further explore ways to eliminate and control Aedes aegypti, we conducted a drinking water tank culture to prevent Aedes aegypti in 1982 in Di Kok Estate, Sheung Uk Estate in Sheung Tak Commune, Lee Uk Tsuen and Sheung Sum Estate in Wa Sha Commune The scene observation. Preventive measures: Before stocking fish, inspect all household water tanks in observation points one by one with and without Egyptian Aedes larvae and register with each stocking tank for 1 to 2 stocks (Nile tilapia or beard Catfish), regularly by hand all the water tank inspection, registration (more than 3 times per month). Based on the housing index and the Brettiler index, the density changes of Aedes aegypti larvae before and after stocking fish were compared. Housing index
