The stability of the positive equilibrium and the existence of Hopf bifurcation are investigated. By using the normal form theory and center manifold argument, the explicit formulae which determine the stability, the direction and the other properties ofbifurcating periodic solutions are derived. Finally some numerical simulations are carried out to illustrate the obtained results. %K Species model of delay %K Hopf bifurcation %K stability %K center manifold argument %K normal form
