Impacts of endectocidal treatments on entomological inoculation rates (EIR) of P. falciparum (a-b) and P. vivax (c-d) following three months of fortnightly endectocidal (ivermectin) applications to pigs alone (a, c) or both pigs and dogs (b, d). Each point within the triangles refers to a relative EIR value that corresponds to a particular distribution of blood meals (human, pigs or dogs). In the absence of any control, annual EIR was set to equal 100 (Reimer, et al. [4]). Note the minimum proportion of human blood meals was 0.4 and 0.3 for P. falciparum and P. vivax to produce R0 > 1. Within those limits, the relative EIR could be dramatically influenced by host choice. For example, in panel a, a mix of blood meal proportions from humans (0.4), treated pigs (0.4) and untreated dogs (0.2) results in a shift in relative EIR to 0.35
