疟疾病媒种群主要由冈比亚按蚊组成。安的一点贡献funestus和An.河流。 在未经处理的蚊帐旁设置灯光陷阱，监测进入卧室叮咬的蚊子。 当浸渍蚊帐提供了所有其他床在一个村庄的按蚊种群下降，但致倦库蚊种群不受影响。 一个人的生存冈比亚（以卵巢发育的平均数衡量），子孢子率在采用蚊帐后下降，估计未使用蚊帐的人的子孢子接种率下降了90%以上。 净引进导致在室内休息的蚊子数量急剧下降，但关于转移到户外休息，动物叮咬，早期叮咬或户外叮咬的证据是不确定的。 喷洒滴滴涕大大减少了按蚊的数量。
The malaria vector population consisted mainly of Anopheles gambiae s.s. with a small contribution from An. funestus and An. rivulorum. The mosquitoes coming to bite in bedrooms were monitored with light traps set beside untreated bednets. When impregnated bednets were provided for all the other beds in a village the Anopheles populations declined but the Culex quinquefasciatus populations were unaffected. The survival of An. gambiae (as measured by the mean number of ovarian dilatations) and the sporozoite rate declined following introduction of the nets and the estimated sporozoite inoculation rates into people not under their nets declined by more than 90%. The net introductions caused sharp declines in the number of mosquitoes resting indoors, but the evidence was inconclusive regarding diversion to outdoor resting, animal biting, earlier biting or outdoor biting. DDT spraying greatly reduced the Anopheles populations.
