Resumen
The dispersal of herbivorous insects in large plantations must be modelled by
taking into account many behavioral aspects of the individual movement. The insect
ability to search for (and find) better plant quality are of fundamental importance to
the development of a mathematical model. Also, many insects present an aggregation
tendency which seems to be a population strategy to optimize harvesting and survival.
In the present work, in order to analyze the spatio-temporal dynamics of an insect
population, both kinds of behaviour are microscopically described by a Coupled Map
Lattice model which includes a short range taxis for plant quality to a long range taxis
with respect to their own population density.
We observed, in the macroscopic scale, stable and dynamical heterogeneous spatial
pattern formation when the difference between the scales is significant.
