Fig 1. Conceptual diagram of compartmental (SIR) model.

Solid lines indicate transitions between model compartments. Dashed lines indicate dependencies. Susceptible humans (H_s) become infected (H_i) at rate T_mh when bitten by infected adult mosquitoes (M_i). Infected humans recover at rate γ and become resistant to infection (H_r). Uninfected adult mosquitoes (M_n) become infected (M_i) at rate T_hm by biting an infected human. Juvenile mosquitoes in each patch (M_j,p) are produced from adult mosquitoes in that patch (M_n,p and M_i,p) at a density-dependent rate, ν, and mature to become uninfected adult mosquitoes (M_n,p) at rate g. Adult mosquitoes in each patch, p, migrate to each adjacent patch, q, at rate D_p,q and migrate from each adjacent patch, q, at rate D_q,p. Adult mosquitoes die and are removed from the population at rate μ.
