Efficacy of pyrethroid‐treated nets against malaria vectors and nuisance‐biting mosquitoes in Tanzania in areas with long‐term insecticide‐treated net use

Abstract

The sustained pyrethroid susceptibility of malaria vectors in Tanzania is encouraging for successful malaria control with ITNs. Continued monitoring is essential to ensure early resistance detection, particularly in areas with heavy agricultural or public health use of insecticides where resistance is likely to develop. Widespread low susceptibility of nuisance-biting Culex mosquitoes to ITNs raises concern for user acceptance of nets.
