含药煤油灯驱避大劣按蚊的室内效果观察

Laboratory Evaluation of Kerosene Lamp Containing Synthetic Pyrethroids to Repel Anopheles dirus

通过实验室内空白对照组、单纯煤油灯组和含药煤油灯组大劣按蚊叮咬频率的比较，证实含有0．05％右旋丙烯菊酯的煤油灯对大劣按蚊具有明显的驱避作用，同时具有一定的击倒和杀死作用。此外，对3组试验中大劣按蚊叮咬的时间分布进行了分析。

This article reported a laboratory evaluation of kerosene lamp containing syntheticpyrethroids to repel Anopheles dims. These test groups were control, kerosene lamp only and kerosenelamp containing 0. 05 % d-allethrin. By comparation of biting frequency of Anopheles dims among thethree test groups, it was confirmed that the obvious effect of kerosene lamp containing 0. 05 % d-allethrinto repel Anopheles dims in the laboratory, which also can kill some Anopheles dims during the test. Thetime distributions of biting by Anopheles dims in the three test groups were also analysed.
