Modeling Aphid Populations

The application of two type of model to aphid populations is discussed, with particular reference to the lime aphid (Eucallipterus tiliae L.). The role of detatailed simulaulation models is briefly reviewed and it is shown that a model of the lime aphid developed in Britain can represent the differing populatation behaviour of the same species in New Zealand. A much simpler, general herbivore/plant model is then applied to the lime aphid in Britain and gives as good a agreement with observed data as did the detailed simulalation model.
