Modeling and Analysis of Integrated Pest Control Strategies via Impulsive Differential Equations

Figure 1

Periodic solution of the impulsive system (14) computed for the parameter values given in Table 1. (a) and (b) show the time histories of the pest and predator populations, respectively, while (c) presents the corresponding phase plot with the solution segments (pesticide spraying, blue) and (predator release, red). Hence, the displayed periodic trajectory has a cyclic solution signature . In what follows, this color code will be used to distinguish the solution segments.
