Dynamical system and nonlinear regression for estimate host-parasitoid relationship
The authors presents a dynamical system for studying the relationship host-parasitoid which permits the estimation of the parasite nymphs using nymphs healthy as the known variable. The model shows the functional answer of the parasitoid, in which a point arrives that its density is not augmented although the number host increases, and it becomes necessary to intervene in the ecosystem. By using a simple algorithm, the authors estimate the parasitoids level using the priori relationship between the host and the climate factors and then the nonlinear model. They study the relation host-parasitoid and use the random sequential samples to do regression models to estimate the parasitoid percent knowing the density host in the crop.
