Abstract
This paper is concerned with the exponential stability of traveling wavefronts for a system modeling the geographic spread of black-legged tick Ixodes scapularis. It is shown in a recent work (Lai and Zou in J Differ Equ 269: 6400-6421, 2020) that this system admits traveling wavefronts when the basic reproduction number is greater than one and the wave speeds are larger than or equal to the asymptotic speed of spread. In this paper, we further study the asymptotic stability of traveling wavefronts. Applying the techniques of weighted energy method and the comparison principle, we prove that the traveling wavefronts with relatively large speed are exponentially stable, when the initial perturbation around the traveling wavefronts decays exponentially as \(x\rightarrow -\infty \), but can be arbitrarily large in other locations.
