Elevated oxidase and esterase levels associated with permethrin tolerance in Anopheles gambiae from Kenyan villages using permethrin‐impregnated nets
It is speculated that use of impregnated nets selected for higher oxidase and esterase levels in An. Expand
Reduced susceptibility of Anopheles gambiae to permethrin associated with the use of permethrin‐impregnated bednets and curtains in Kenya
Abstract. Susceptibility of the malaria vector Anopheles gambiae to permethrin decreased following the installation of mosquito nets impregnated with 0.5 g permethrin per square metre in fourExpand
Dynamics of the pyrethroid knockdown resistance allele in western Kenyan populations of Anopheles gambiae in response to insecticide-treated bed net trials.
Permethrin and DDT resistance in Anopheles gambiae s.s. associated with a leucine-serine knockdown resistance (kdr) mutation in the voltage-gated sodium channel gene was discovered recently inExpand
The reservoir of Plasmodium falciparum malaria in a holoendemic area of western Kenya.
The reservoir of infectious Plasmodium falciparum gametocytes in a population living in an area of holoendemic malaria in western Kenya was estimated by directly feeding mosquitoes on volunteers and Calculations indicated that children under 10 years of age were responsible for 72% of mosquito infections.

Spatial distribution of anopheline larval habitats in Western Kenyan highlands: effects of land cover types and topography.
The distributions of anopheline larval habitats were aggregated in valley bottoms in Kenya in both the rainy and dry seasons, although the degree of aggregation was higher in the dry season than inExpand
Wash durability and optimal drying regimen of four brands of long-lasting insecticide-treated nets after repeated washing under tropical conditions
The results of this study suggest that washing and drying regimen influence the insecticidal activity of LLINs and there is need to educate net users to adopt a more gentle washing procedure while handling LLIns. Expand
Evidence for a useful life of more than three years for a polyester-based long-lasting insecticidal mosquito net in Western Uganda
Under conditions in Western Uganda the tested long-lasting insecticidal net Interceptor® fulfilled the criteria for phase III of WHO evaluations and, based on preliminary criteria of the useful life, this product is estimated to last on average between three and four years. Expand
Some observations on the biting behavior of Anopheles gambiae s.s., Anopheles arabiensis, and Anopheles funestus and their implications for malaria control.
Studies were carried out in three villages in western Kenya on the biting behavior of Anopheles gambiae s.s., Anopheles arabiensis, and Anopheles funestus. Blood feeding behavior and departure fromExpand
Long-term field performance of a polyester-based long-lasting insecticidal mosquito net in rural Uganda
Second generation PermaNet® showed excellent results after three years of field use and fulfilled the WHOPES criteria for LLIN, while loss of insecticide on LLIN using coating technology under field conditions was far more influenced by factors associated with handling rather than washing. Expand
Spatial and temporal variation in the kdr allele L1014S in Anopheles gambiae s.s. and phenotypic variability in susceptibility to insecticides in Western Kenya
The persistence of A. arabiensis, despite little or no detectable insecticide resistance, is likely due to behavioural traits such as outdoor feeding and/or feeding on non-human hosts by which this species avoids interaction with insecticide-treated nets. Expand
