Figure 4

The variations in the sizes of total questing nymphs and infected questing nymphs with the two temperature settings mentioned above. The red solid curves represent the outputs by seeding the model with 1961−1990 temperature data (${\mathcal{R}}_v=1.38$ and ${\mathcal{R}}_0=0.90$ in this case), while the blue dashed curves represent the model outputs by 1981−2010 temperature data (${\mathcal{R}}_v=1.62$ and ${\mathcal{R}}_0=1.19$ in this case). (a) Total questing nymphs; (b) infected questing nymphs in the 40 year simulation; (c) seasonality of questing nymphs at the steady state; (d) seasonality of infected questing nymphs at the steady state, where shaded portions in both (c) and (d) represent the active seasons of the questing nymphs.
