Summary A simple simulation model was developed to simulate the population dynamics of the system of the greenhouse whitefly ( Trialeurodes vaporariorum Westwood ) and the parasitoid Encarsia formosa Gahan . On the assumption that temperature is constant, the whitefly population was described as the Leslie Matrix model. Parasitization and host feeding by the parasitoid population were modelled by means of a modified disc equation. The validity of the model was demonstrated by comparing the predictions of the model with the observed values obtained in greenhouse experiments.
