Abstract
In this paper we study the dynamics of two competing species model, one of the competing species is stage structured and the disease spreads only in the other competing specie. In order to keep the model simple, we present it under the strong assumption that the disease cannot cross the species barrier. Dynamical behaviors such as positivity, roundedness, stability, bifurcation and persistence of the model, are studied analytically using theories of differential equations. Computer simulations are carried out to substantiate the analytical findings. It is noted that the parameters, c the loss rate of population, t the maturation time and f the intraspecific coefficient are the key parameters which we need to control to keep away the mature healthy population from extinction and the infected individuals of the latter species from extinction respectively.
Key words: Competing species, stage structure, disease, stability, permanence, numerical simulation.
