Abstract
AbstractThis paper portrays the dynamics of pine wilt disease. The specific formula for reproduction number is accomplished. Global behavior is completely demonstrated on the basis of the basic reproduction number $${{\boldsymbol{R}}}_{{\boldsymbol{o}}}$$Ro. The disease-free equilibrium is globally asymptotically stable for $${{\boldsymbol{R}}}_{{\boldsymbol{o}}}{\boldsymbol{ < }}{\bf{1}}$$Ro<1 and in such a case, the endemic equilibrium does not exist. If $${{\boldsymbol{R}}}_{{\boldsymbol{o}}}$$Ro exceeds one, the disease persists and the unique endemic equilibrium is globally asymptotically stable. Global stability of disease-free equilibrium is proved using a Lyapunov function. A graph-theoretic approach is applied to show the global stability of the unique endemic equilibrium. Sensitivity analysis has been established and control strategies have been designed on the basis of sensitivity analysis.
