Figure 4.

Predicted distributions of the lifetime egg production of An. arabiensis: (a) feeding exclusively on hosts of different species and (b) taking a mixture of blood meals from cows and humans using bednets. The dotted black line represents An. arabiensis fitness under a ‘human-using-a-bednet’-only diet and the solid blue line a cow-only host diet. Dotted lines show expected distributions for variable proportions of cow-feeding (all other meals from humans using a bednet). Blue lines indicate host diets yielding a statistically significant advantage over an exclusive human-using-a-bednet diet (black dotted line). (c) shows the predicted distribution of An. gambiae s.s. lifetime egg production feeding exclusively on different host species. All distributions are based on 10 000 simulations, with host type abbreviations as specified in figure 1.
