Insecticide resistance status of three malaria vectors Anopheles gambiae (s.l.) An. funestus and An. mascarensis from the south central and east coasts of Madagascar

摘要

BackgroundInsecticide-based vector control, which comprises use of insecticide-treated bed nets (ITNs) and indoor residual spraying (IRS), is the key method to malaria control in Madagascar. However, its effectiveness is threatened as vectors become resistant to insecticides. This study investigated the resistance status of malaria vectors in Madagascar to various insecticides recommended for use in ITNs and/or IRS.
