DEVELOPMENT OF A COMPUTER-SIMULATION MODEL FOR A PLANT-NEMATODE SYSTEM

Abstract

A computer-simulation model (MELSIM) of a Meloidogyne-grapevine [Vitis] system was developed. The objective was to attempt a holistic approach to the study of nematode population dynamics by using experimental data from controlled environmental conditions. A simulator with predictive ability would be useful in considering pest management alternatives and in teaching. Rates of flow and interaction between the components of the system are governed by environmental conditions. Equations for these rates are determined by fitting curves to data from controlled environment studies. Development of the model and trial simulations revealed deficiencies in understanding of the system and identified areas where further research is necessary.
