Abstract :
Traditional models state that both prey and predator population depend each other and they follow same cycle indefinitely until an external force is used. In this manuscript the effect of epidemics on two/three species prey-predator system under the influence of epidemics is studied using time delay models. A z-shaped function in prey-predator mathematical model to find the effect of epidemics is introduced. After the epidemics both prey and predators showed a constant rate of change in population. In three species model the second predator and prey species are not directly dependent so the effect of less number of prey species affects the second predator gradually so it does not show large variations whereas it keeps a linear behavior.
