Protective efficacy (% PE) of several mixtures of 6-methyl-5-hepten-2-one and geranylacetone in different ratios and tested at different concentrations in arm-in-cage experiments with An. gambiae mosquitoes. Asterix indicate significant differences between 6-methyl-5-hepten-2-one (6MHO) alone and Mixture 3 (1:1, 6MHO:GA) and between geranylacetone (GA) alone and Mixture 3 (1:1, 6MHO:GA) (*p < 0.05; ** p < 0.01; ***p < 0.001).
