Recently, the most convincing evidence of complex dynamics and chaos in biological populations has been presented for Tribolium castaneaum , a classic laboratory model insect. In this note, the robustness of this system is investigated and a constant immigration term is added to the adult population equation. It has been found that such perturbation to the model can either have a complicating effect (when the isolated system is periodic) or a simplifying one (when the system is chaotic in isolation).
