Various pyrethroids on bednets and curtainsCurtisC. F.MyambaJ.WilkesT. J. London School of Hygiene & Tropical Medicine London UK Ubwari Field Station Tanga Tanzania 001992873363370Verandah trap huts in Tanzania village were used to assess the effectiveness if impregnated bednets and curtains in preventing hut entry and feeding by, and in killing of, Anopheles gambiae and An. funestus. Permethrin, Δmethrin, lambdacyhalothrin and pyrethrum were used for impregnation of damaged or undamaged bednets, sisal eaves curtains or bed curtains made of polypropylene fibre. The performance of the synthetic pyrethroids did not differ statistically significantly, except that on a damage net permethrin was better at preventing feeding. sisal eaves curtains deterred mosquitoes from hut entry but did not kill those that had entered. In assessing damaged nets and curtains it must be recognised that anything less than the best vector control may have no appreciable impact on holoendemic malaria.Anopheles gambiaeAnopheles funestusimpregnated bednetsverandah trap hutsimpregnated curtainsmalaria vector controlFull text available only in PDF format.Texto completo disponível apenas em PDF.
