Overall impact of insecticides on mosquito behaviour insides houses. The graph illustrates the mode of action of DDT, Transfluthrin and Metofluthrin coils on mosquito behaviour. The outcomes measured included deterrence, irritancy, feeding inhibition and toxicity. The value of deterrence was derived from the effect of insecticides on An. arabiensis mosquitoes from field experiments and irritancy, feeding inhibition, mortality and fecundity of An. gambiae s.s. mosquitoes from the semi field system experiment.
