Delayed mortality effects cut the malaria transmission potential of insecticide resistant mosquitoes [PDF]

open access: yes, 2016
Malaria transmission has been substantially reduced across Africa through the distribution of long-lasting insecticidal nets (LLINs). However, the emergence of insecticide resistance within mosquito vectors risks jeopardizing the future efficacy of this ...
