Mathematical Modeling in Plant Protection

We studied the mathematical model of ¿predator-prey¿ and ¿pest-parasite¿. In that case the components of the system are continuously changing. We describe the system by two differential equations which concludes into numeral equation by integrators and variables. For forecasting, we used the method based on the dynamic rows, which we suggest that can be determined by its state for a future period from current chain of changes. Design parameters for reliability usage and distribution and the criteria Hoset¿s (Student's) made calculations for a long interval. Materials accepted on the basis of graphical analysis allows you to make fairly accurate predictions in order to identify the trend and correct solution. The greatest advantage of this method lies in the simplicity of the construction schedule and convenience to read it. We showed the detailed analysis for a predator-prey system. Our results are linked with biological systems in the real world. In this book, a systematical analysis of a ¿predator-prey¿ system based on mathematical approach is proposed. The obtained results provide some new insights on dynamics, which play important roles in maintaining biosystems' diversity.
