本文报道实验观察人体对蚊的相对吸引力。试验在冈比亚乡村Walikunda地区进行。该区旱季出现阿拉伯按蚊的密度高峰,但疟疾传播甚低;而在传播季节的雨季,主要媒介冈比亚按蚊(狭义)是优势蚊种。 在苏丹草原建6间相同的泥墙草顶的试验小屋,每间约2.5m~2,间距12m,排列在一大块水稻田边缘。水稻田是区内蚊的主要孳生地。蚊通过两侧屋檐下缝隙进入小屋内。从 This article reports the experiment to observe the relative attractiveness of the human body to mosquitoes. The experiment was conducted in the Walikunda area in the Gambia countryside. The mosquito density peaked in the dry season in this area, but malaria transmission was very low; in the rainy season during the transmission season, the dominant vector Anopheles gambiae (narrow sense) was the dominant mosquito species. In the Sudan steppe, six identical test slime walls with a height of about 2.5m ~ 2 and a spacing of 12m were arranged on the edge of a large paddy field. Paddy fields are the major breeding grounds for mosquitos in the area. The mosquito enters the cabin through the crevices on both sides of the eaves. From
