Simulation of the model {(2.2)–(2.6)}, showing the profile of total adult mosquito population at steady-state, as a function of temperature, for the case with high fitness costs (ξ^RS = 1.01, ξ^RR = 1.30) and various levels of adulticide coverage (C_M). (a)–(d) Simulations carried out in the absence of density-dependent larval mortality (i.e. ${\Psi }_L^i=0$, i = {SS, RS, RR}). (e)–(h) Simulation carried out in the presence of density-dependent larval mortality (i.e. ${\Psi }_L^i\ne 0$, i = {SS, RS, RR}). Other parameter values used in the simulations are as given by the baseline values in Table 5, Table 6 The functional forms of the temperature-dependent parameters of the model are described in Section 2.4, and are evaluated at fixed temperatures ranging from 17 °C to 36 °C.
