Abstract
The effect of aggregated parasitoid on a host-parasitoid system are investigated qualitatively by computer simulation. Our numerical simulations show that the aggregation of parasitoid can stabilize the population dynamics when the density-dependent effects of host is weak, while it can also destabilize the system when the density-dependent effect of host is strong. A variety of complex population dynamics including chaotic bands with narrow or wide periodic windows, pitchfork and tangent bifurcation, period-doubling bifurcation and period-halving bifurcation, attractor crises, intermittent chaos, supertransients and multiple attractors with fractal basins of attraction are obtained.
