We derive a dynamic model for a plant herbivore system describing the interaction of a gall-forming aphid and a single plant. We compare the behavior of our model with experimental observations obtained from an aphid plant system studied by Whitham (Whitham, T.G. 1978, Habitat selection of Pemphigus aphids in response to resource limitation and competition. Ecology 59, 1164-1176). A simple parameter estimation shows a close correlation between the predicted and observed results.
