Figure 2

Bifurcation diagram of$i_h^{\ast }$versus A) biting rate a for parameter set 1 and the first set of initial conditions; and B) mosquito mortality rate μ ₂ for parameter set 2 and the first set of initial conditions, for all five models. Because all five models are pictured at once, the unstable branch of the bifurcation given by the disease-free equilibrium is not pictured. Note that the ordering of magnitude is preserved for the range in which the parameter is varied, except for the McKenzie and Chitnis models.
