AN APPROACH TO STUDY OF TWO COMPETITIVE PREY ONE PREDATOR MODEL WITH DISEASE IN PREDATOR

Rachna Soni and Usha Chouhan

Abstract

This paper is concerned with two prey one predator model with disease in predator. Existence and stability of equilibrium points are studied. The dynamics of the model depends on the numbers of interactions between the preys and predators. The two preys are competitive in nature. Predation can have a stable dynamical impact on the system only if the harvesting rate of susceptible predator is less than the harvesting rate of the infected predator and the system has no periodic solution.
