A Holling Type II Discrete Switching Host-Parasitoid System with a Nonlinear Threshold Policy for Integrated Pest Management

Figure 10

Basins of attraction of three coexisting attractors of system (4). The range of the left one is . The blue, magenta, and green regions are attracted to the attractors shown in Figure 9 from left to right. The right one is an enlargement of the basins of attraction with range . The parameters are fixed as follows: . The white lines in each subplot represent the switching curves.
