Increasing pyrethroid resistance in malaria vectors has been reported in
western Kenya where long lasting insecticidal nets (LLINs) and indoor residual spraying
(IRS) are the mainstays of vector control. To ensure the sustainability of insecticide-based
malaria vector control, monitoring programs need to be implemented. This study was
designed to investigate the extent and distribution of pyrethroid resistance in 4 Districts of
western Kenya (Nyando, Rachuonyo, Bondo and Teso). All four Districts have received
LLINs while Nyando and Rachuonyo Districts have had IRS campaigns for 3–5 years using
pyrethroids. This study is part of a programme aimed at determining the impact of insecticide
resistance on malaria epidemiology. Methods Three day old adult mosquitoes from larval
samples collected in the field, were used for bioassays using the WHO tube bioassay …
