Development of an Intelligent Robot for an Agricultural Production Ecosystem (III) - Modeling of the Predation of Rice Plants and Weeds by Golden Apple Snail -

摘要

Models of the predation of rice plants and weeds by golden apple snails based on the Lotka-Volterra equations and the equations of Holling are introduced in this researching. These prediction equations are useful to estimate the number of snails in different phases of the rice crop season; however they should be modified to fit better to the rice production ecosystem and then this information will be used for the agricultural production robot in order to make decisions about the appropriate timing for removing the snails in excess in paddy field.
