Abstract
An individual-based model for Drosophila is formulated, based on
competition amongst larvae consuming the same batch of food. The
predictions of the model are supported by data for single species
Drosophila populations reared in the laboratory. The model is used to
build a simple discrete model for the dynamics of Drosophila populations
that are kept over a number of generations. The dynamics of a single
species is shown to give either a stable equilibrium or fluctuations
which can be periodic or chaotic. When the dynamics of a species in the
absence of the other is periodic or chaotic, we found coexistence or two
alternative states, on neither of which the species can coexist.
