试验用的蛉种是实验室饲养羽化的恶毒白蛉。以瑞士的避蚊胺(Deet)、美国的避蚊酮(Indalone)及西德的牛蝇畏(MGK_(11))三种驱避剂试验,比较其效力。受试者为21名不同年龄的男女志愿者。对每种驱避剂均作了30次的重复试验,每次试验时将受试者涂药前臂置蛉笼底的5个孔下暴露10分钟,笼内放20只不经产的雌蛉。试验所得数据经概率分析并计算95％的可信限。
The species used in the experiment is the virulent whitefly that emerges from laboratory rearing. The efficacy of three repellents was tested in Switzerland, including Deet, Indalone in the United States, and Feverweed in West Germany (MGK_ (11)). Subjects were 21 men and women of different ages volunteers. Each repellent was tested 30 times in duplicate, exposing the subject to 5 holes at the bottom of the forearms for 10 minutes in each trial, and 20 unproductive females in the cage . The experimental data were probabilistically analyzed and a 95% confidence limit calculated.
