Three pyrethroids, OMS-3002, OMS-3004 and OMS-3021 were tested in the experimental station of Soumousso (Burkina Faso), a WHO reference centre. Total indoor house-spraying was carried out in Bobo and Mossi huts, using a Hudson type sprayer at doses of 1 g/m2 for OMS-3002, 0.1 g/m2 for OMS-3004 and OMS-3021. The density of Anopheles gambiae and Anopheles funestus collected in huts treated with OMS-3002 was reduced by 70%: a 94% exit rate was observed in the treated huts (compared to 33% in the control) as well as a significant drop in the feeding rates and an overall mortality of 48%. With OMS-3004 and OMS-3021, the number of females entering the huts dropped by 73% and 55%, respectively; the feeding rates were also significantly reduced. Exit rates increased (81% and 91%, respectively) as well as the overall mortality (83% for OMS-3004 and 89% for OMS-3021). These promising results offer favourable prospects for the use of these insecticides in an integrated malaria vector control policy.
三种拟除虫菊酯，即OMS - 3002、OMS - 3004和OMS - 3021，在布基纳法索的苏穆索实验站（世界卫生组织参考中心）进行了测试。在博博和莫西小屋内进行了全面室内喷洒，使用哈德逊型喷雾器，OMS - 3002的剂量为1克/平方米，OMS - 3004和OMS - 3021的剂量为0.1克/平方米。在使用OMS - 3002处理过的小屋中采集的冈比亚按蚊和恶疟按蚊密度降低了70%：在处理过的小屋中观察到94%的逃离率（对照组为33%），以及摄食率显著下降和总体死亡率为48%。使用OMS - 3004和OMS - 3021时，进入小屋的雌蚊数量分别下降了73%和55%；摄食率也显著降低。逃离率增加（分别为81%和91%）以及总体死亡率增加（OMS - 3004为83%，OMS - 3021为89%）。这些有前景的结果为在疟疾媒介综合控制政策中使用这些杀虫剂提供了有利前景。
