Table 5. Sensitivity indices of for the Model (1) at the baseline parameter values in Tables 2 and 3.
As can be seen from the table, for Ae. aegypti mosquitoes, the most sensitive parameter is the mosquito death rate, μv. However, for Ae. albopictus mosquitoes, the most sensitive parameter is the mosquito biting rate, σv, and the least sensitive parameter is the incubation rate for humans, νh.
