目的:研究福州市建筑工地登革热传播媒介白纹伊蚊的孳生现状与药物控制方法,为制订防制措施提供科学依据。方法:采用捞勺和人诱法进行现场测定伊蚊幼、成蚊的密度,用溴氰菊酯、三氯杀虫酯、倍硫磷等药物制成烟薰、喷杀、缓释剂等卫生杀虫剂,用对比法观察计算杀灭前后伊蚊的密度下降情况。结果:调查350家建筑工地的积水分布状况,长期积水为252个,占72％;积水数为3850处,其中有幼虫孳生为2402处,占62.38％。使用溴氰菊酯、三氯杀虫酯作为烟薰杀虫剂,2d内成蚊密度分别下降80％和60％;用溴氰菊酯、倍硫磷作为喷杀剂,1d内成蚊密度分别下降98％和100％,制成缓释剂,幼蚊密度1d内分别下降100％和98％。结论:福州市建筑工地普遍生白纹伊蚊,并多与致倦库蚊共生占87％,与三带喙库蚊或三蚊种共生占4％,伊纹在6～20m2积水里仍可以孳生。用三氯杀虫酯烟薰灭工地地下密闭部位的成蚊,倍硫磷喷杀剂灭成蚊,溴氰菊酯缓释剂杀灭较大积水中的幼、成蚊均具有较好效果,可将白纹伊蚊密度降至不足为害的水平。“,”Objective: To investigate the multiply situation and medical control of Ae. albopictus, the transmission vector of DF, in conttruction sites Fuzhou and to offer scientific basis for stipulating the prevention and control methods. Method: To deterrmine the varying densities by spooning larvae and artificially luring mosquito. Adopt icsecticides of deltamethrin, tetradiphon and fenthion. then compare the diffenet densities before and after their adoption. Result: Investigate the status quo of the accumulated ...
