Figure 9From: Complex dynamics and coexistence of period-doubling and period-halving bifurcations in an integrated pest management model with nonlinear impulsive controlTwo coexisting attractors of model (17) with \(\delta =0.31\). The other parameter values are identical to those in Fig. 8. The initial conditions are: \((A-B)(x_{0},x_{0})=(2.2,2.9); (C-D)(x_{0},x_{0})=(2.7,2.5)\)Back to article page
