Map showing the study region in eastern Uganda. The four maps show the average predicted An. gambiae (s.l.) and An. funestus (s.l.) relative density per household per night, respectively, before (a, b) and after (c, d) IRS based on the Bayesian spatio-temporal model. The maps are normalised by the mean at 100 m spatial resolution. Thus, the highest predicted pre-IRS density for An. gambiae (s.l.) was 2.4 times as high as the mean compared to a prediction of 7.6 for An. funestus (s.l.)
