Effect of indoor-based insecticide control on the relative abundance of African vector populations. Plots show the effect of indoor residual spraying (a) and long-lasting insecticidal nets (b) on the relative abundance of An. funestus (blue), An. gambiae/An. coluzzii (green) and An. arabiensis (red), with a hypothetical pre-intervention relative abundance of 0.1 (An. funestus), 0.43 (An. gambiae/An. coluzzii) and 0.47 (An. arabiensis), indicated by vertical dashed lines. Estimates of post-intervention relative abundances are uncertain and are represented by their 95 % confidence bands (coloured rectangles) and maximum likelihood values (vertical solid lines). The maximum likelihood estimate of the intervention effect on relative abundance for each species is indicated by the arrows linking the pre-and post-intervention estimates
