我区某部驻疟疾暴发区,为防治疟疾,1990年5～12月,我们用奋斗呐浸泡蚊帐防治蚊媒,控制疟疾,效果简报如下。(一)材料与方法用5%奋斗呐可湿性粉剂浸泡蚊帐,药量为20～25mg/m~2。选择疟疾发病率较高的4个连队为固定密度调查点,分别设为实验组和对照组。定时于23:30～24:00时从4组(4个连队)中各抽取20顶蚊帐,计算其蚊密度,并鉴定蚊虫。
In order to prevent and control malaria, a certain area of our district was stationed in a malaria outbreak area. From May to December 1990, we used the struggle to soak mosquito nets to prevent mosquito vectors and control malaria. The briefing is as follows. (A) materials and methods with 5% of the struggle na wettable powder soaked mosquito nets, the dose of 20 ~ 25mg / m ~ 2. The four companies with higher incidence of malaria were selected as fixed density investigation points and set as experimental group and control group respectively. 20 mosquito nets were drawn from each of the 4 groups (4 companies) at 23:30 ~ 24:00, the mosquito density was calculated and the mosquitoes were identified.
