Fig. 4From: Anopheles gambiae populations from Burkina Faso show minimal delayed mortality after exposure to insecticide-treated netsThe longevity of field populations after multiple WHO cone bioassay exposures. Kaplan Meier survival curves show the proportion alive each day following four exposures every four days (a); or five daily exposures (b). In both a and b the dashed grey line indicates the day mosquitoes were exposed. Crosses represent censored data at the point of censoring. Immediate (within 24 h) mortality is excludedBack to article page
