Global dynamics of a pine wilt disease transmission model with nonlinear incidence rates

摘要

In this study, we investigate a pine wilt transmission model with nonlinear incidence rates. The stability of the system is analyzed for disease-free and endemic equilibria. It is proved that the global dynamics are completely by the basic reproduction number R_0. If R_0 is less than one, the disease-free equilibrium is globally asymptotically stable, and in such a case, the endemic equilibrium does not exist. If R_0 is greater than one, the disease persists and the unique endemic equilibrium is globally asymptotically stable.
