为了通过人类诱饵的吸引来准确测量疟疾传播，在按蚊密度高的喀麦隆村庄比较了三种远距离人类诱饵捕获蚊子的方法。这三种方法是：1）经典的人类登陆捕获，其中人同时处于诱饵和捕手状态；2）单网作为陷阱；3）双网，其中外网作为陷阱，内网避免蚊虫叮咬。人类登陆时人均按蚊密度比单网高 1.6 倍，比双网高 4.7 倍。在这三种方法中，捕获的按蚊种类及其各自的比例的结果相似。黑按蚊和按蚊的样本。冈比亚具有相对胎次率和子孢子指数。根据这些结果，为了估计疟疾的传播情况，可以设想将人类诱饵的标准捕获量改为人类携带的单床网捕获量，相反，双网由于其效果不佳而必须被丢弃。
In order io gel an accurate measure of malaria transmission by mean of human bait attraction, three methods of catches far human-bail mosquitoes were compared in a Cameroonian village of high anopheline density. These three methods were 1) the classical human landing catches where the man was in the same time bait and catcher, 2) the single-nets which acted as a trap and 3) the double-nets where the outer nei acted as a trap and the inner avoided mosquito bites. The anopheline densities per man with human landings were 1.6 time higher than those obtained with single-nets, these later being 4.7 times higher than those obtained with double-nets. in the three methods, the results were similar for the anophelines species catched and for their respective proportions. The samples of Anopheles nili and An. gambiae had comparative parity rates and sporozoitic indexes. From these results, in order io estimate the malaria transmission ii con be envisaged io change the standard human-bait catch for the human-bailed single bed-net catch, on the contrary the double-net have to be discarded because of their poor results.
