在冈比亚的一个内陆地区，用斜坡诱捕器测量了在距离一对诱饵小牛或等值二氧化碳源连续距离处飞行的蚊子密度，以确定开始朝向诱饵的最大范围。在66个夜晚，以7.5 m至60 m的间隔放置36个陷阱。齐曼按蚊；在22.5 ~ 30 m范围内，均匀曼蚊和伊蚊对诱饵的存在有明显的反应；以二氧化碳为诱饵，同一物种在15 m处表现出明显的反应，但除均匀田鼠外，在22.5 ~ 30 m处没有明显的反应。非洲斑蝽对15米范围内的小牛和二氧化碳诱饵都有反应，但对更远的范围则没有反应。库蚊。C. univittatus Theo。在7.5 m处有响应，但在更大距离处无响应。即使在最近的陷阱（7.5 m）中，decenens组对两种饵料均无反应。与饵料的距离不同，产卵率也不同。在被螨感染的雌性比例中没有发现类似的变化。
In an inland area of the Gambia the density of flying mosquitoes at successive distances from a pair of bait-calves or an equivalent source of carbon dioxide was measured with ramp-traps to determine the maximum range at which orientation towards the bait was initiated. Thirty-six traps were operated at intervals of 7·5 m up to a distance of 60 m from the bait, on 66 nights. Anopheles ziemanni Grünb., Mansonia uniformis (Theo.) and Aedes spp. were responding to the presence of the baitcalves from a distance of 22·5–30 m; with carbon dioxide as bait the same species showed a clear response at 15 m but, with the doubtful exception of M. uniformis, not at 22·5–30 m. M. africana (Theo.) responded to both calf and carbon dioxide baits at 15 m but not at more distant ranges. Culex thalassius Theo. and C. univittatus Theo. showed a response at 7·5 m but not at any greater distance. C. decens group showed no response to either bait even in the nearest traps (7·5 m). The parous rate in Mansonia spp. varied with distance from the bait. Similar variation in the proportion of females infested with mites was not detected.
