Our researches are concerned with a class of planar general equivariant system of nine degrees. By making two appropriate transformations of system and calculating focal values carefully, we obtain the conditions that the infinity and three elementary focuses 2 ) become four general centers at the
## Abstract In this paper, by using a corollary to the center manifold theorem, we show that the 3βD foodβchain model studied by many authors undergoes a 3βD Hopf bifurcation, and then we obtain the existence of limit cycles for the 3βD differential system. The methods used here can be extended to
