Exposure of Anopheles gambiae larvae to a sub-lethal dose of an agrochemical mixture induces tolerance to adulticides used in vector control management

•Exposure to agrochemicals can affect the tolerance of mosquitoes larvae to insecticides.•The potential carry-over of such effect to the adult stage has been far less documented.•Exposure of An. gambiae larvae to agrochemicals increase tolerance to Fludora® fusion in adults.•Fludora® fusion efficacy for vector control may be locally affected by the ecological context.
