title: [Field trial of the efficacy of 3 pyrethroids in the control of malaria vectors].
abstract: 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.
