Abstract: The population dynamics equation of Jones and Perry has been used for the development of a model that will permit simulations to be made of within-field changes in population densities of potato cyst nematodes. Detailed information from one field has allowed us to estimate the most appropriate values for that field of the input parameters required by the model. Analyses of the sensitivity of the model to these parameters are presented. A convenient input screen has been designed to allow input parameter values to be specified for input of either average field population densities or datasets of within-field distributions, and examples of the latter are given. Other purposes for which the model can be used, such as modelling nematode population changes through rotations or following nematicide treatments, are also illustrated.
