摘要
An eco-epidemiological model with disease in the predator is studied in this paper. Maturity and digestion delay are considered. It is assumed that the infected predator can't prey. The existence of disease-free and endemic equilibria are obtained. The conditions of locally asymptotic stability of equilibria are obtained by discussing eigenvalue equations of the equilibria. Furthermore, global asymptotic stability of disease-free equilibria and the conditions under which the model hold a Hopf bifurcation are discussed, and a numerical simulation is given.
