摘要：

The problem of chaos in second-order predator-prey models with sinusoidally perturbed parameters is investigated in this paper. The analysis is carried out numerically, by means of a continuation method producing bifurcation curves in two-dimensional spaces. The results show that the phase separating two sinusoidal perturbations in time is a strategic variable for controlling the dynamics of the populations. In a large region of the parameter space, phase determines whether the behaviour of the system is chaotic or non-chaotic.
