Figure 7From: The insecticide resistance status of malaria vectors in the Mekong regionThe time for 50% knockdown (KDT50) in function of the observed mortality for four different insecticides. Only tests were included when 80 or more mosquitoes were tested and when the morphological identification was reliable (90% of more correct identifications). The resistance cut off value of 80% mortality is indicated by a dotted line.Back to article page
