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.
疟蚊种群主要由冈比亚按蚊构成，此外还有少量的恶疟按蚊和溪流按蚊。在未处理蚊帐旁设置诱蚊灯来监测进入卧室叮咬的蚊子。当为一个村庄的所有其他床铺提供浸药蚊帐时，按蚊种群数量下降，但致倦库蚊种群数量未受影响。引入蚊帐后，冈比亚按蚊的存活率（以卵巢扩张的平均数量衡量）和子孢子率下降，且未使用蚊帐人群的估计子孢子接种率下降了90%以上。引入蚊帐后，室内栖息的蚊子数量急剧下降，但关于蚊子转向室外栖息、叮咬动物、提前叮咬或在室外叮咬的证据尚无定论。喷洒滴滴涕极大地减少了按蚊种群数量。
