Abstract: The An.anthropophagus density and malaria incidence were observed in the areas that were discontinued bednets impregnation with deltamethrin in Seng Qiao and Zao Wu town of Jing Shan County and Zao Shi town of Tian Men city.Average density of An.anthropophagus was 0.53 per net pretreatment,0 per net during treatment,0.029、0.056 and 0.28 per net respectively were observed in 1st、2nd、3rd year after discontinuing bednets impregnation.Malaria incidence was 51.17 per ten thousand before treatment,4.10 per ten thousand during treatment,4.63、14.55 and 9.50 per ten thousand respectively in 1st、2nd、3rd year after discontinuing treatment.An.anthropophagus density and malaria incidence were decreased very soon during bednets impregnation,but they rised again during discontinuing bednets impregnation year by year.

摘要: 目的:观察停用溴氰菊酯浸泡蚊帐后嗜人按蚊密度与疟疾发病情况。方法:白天用指管扣捕蚊帐内按蚊,并分类计数;同时收集观察区疟疾发病情况。结果:嗜人按蚊密度(只/帐)灭蚊前平均为0.53,灭后降为0,停用药物蚊帐后第1~3年分别为0.029、0.056、0.28;疟疾发病率(例/万)灭蚊前平均为51.17,灭蚊期降至4.10,停用药帐后第1~3年分别为4.63、14.55、9.50。结论:溴氰菊酯浸帐灭蚊,能迅速降低嗜人按蚊密度和疟疾发病率;但停用药帐后,嗜人按蚊密度和疟疾发病率均呈逐年回升趋势。
