Due to the rapid extension of pyrethroid resistance in malaria vectors worldwide, manufacturers are developing new vector control tools including insecticide mixtures containing at least two active ingredients with different modes of action as part of resistance management. Olyset Plus is a new long lasting insecticidal net (LLIN) incorporating permethrin and a synergist, piperonyl butoxide (PBO) into its fibres in order to counteract metabolic based pyrethroid resistance of mosquitoes. In this study we evaluated the efficacy of Olyset Plus both in laboratory and field against susceptble and multi resistanct malaria vectors and compared with Olyset Net which is a permethrin incorporated into polyethylene net.
