以往研究结果表明,在喀麦隆的农村森林地区,疟疾的主要传播媒介为乌有按蚊(An.nili)和穆歇按蚊(An.moucheti),冈比亚按蚊(An.gambiae)起次要作用,而密度甚低的催命按蚊(An.funestus)并不具有重要的流行病学意义。但是,最近在该地区的一些村庄发现了高密度的催命按蚊,本文报道了这类按蚊的生态学及其对疟疾的传播作用。 Previous findings show that in rural areas of Cameroon the main malaria transmission vectors are secondary to An.nili and An.moucheti and An.gambiae, The low density of An.funestus does not have important epidemiological implications. However, a high density of Anopheles dysentery has recently been found in some villages in the area and this paper reports on the ecology of such anopheles mosquitoes and their spread to malaria.
