The Effect of Disease and Harvest in the Eco-Epidemical Food Chain Model

This paper describes a three species food web model with linear functional response andincidence disease. This model consisting of a prey, intermediate predator and top predator whereharvesting of top predator species and SIS disease spread in prey are taken into consideration. Thestability analysis of all possible equilibrium points are carried out. We discussed the effect both ofharvest and disease on the stability of this model. Finally, we used the numerical simulations toverify the analytical results.
