Description
Summary:The main purpose of this paper is to study a predator – prey dynamical system consisting of three species prey, specialized predator and generalist predator namely H (t), I (t) and J (t) respectively, w food web and refuge for the prey and specialized predator population. The consider system has five equilibrium points  A0=(0, 0, 0),  A1=(1, 0, 0), A2=(h, i, 0), A3=(h, 0, j), and the positive equilibrium point A4=(h, i, j)   .The stability and bifurcation of the equilibrium points was studied and the main influence was the qualitative behavior of the solution. It was found that A0  was unstable while the other equilibrium points are stable under condition so we study their bifurcation and we show that A1,A2,and A3  are transcritical while A, is saddle node bifurcation. Numerical simulations were used to illustrate the occurrence of local bifurcation of this model.
