A cellular automata model for citrus variegated chlorosis

A review of the main results obtained by a cellular automata model recently proposed to analyze the progress of citrus variegated chlorosis epidemics is done. In this model epidemiological and environmental features, such as motility of sharpshooter vectors which perform Lévy flights, hydric and nutritional level of plant stress and seasonal climatic effects, are included. The observed epidemics data were quantitatively reproduced by the proposed model varying the parameters controlling vectors motility, plant stress and initial population of diseased plants.
