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

Abstract: 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 . If is less than one, the disease-free equilibrium is globally asymptotically stable, and in such a case, the endemic equilibrium does not exist. If is greater than one, the disease persists and the unique endemic equilibrium is globally asymptotically stable. [Copyright &y& Elsevier]
