Abstract: In this paper we present a simple diffusion model for sterile male codling moth dispersal, to investigate the effect of orchard boundaries on the pattern of spread of released sterile male codling moths. The codling moth is an important pest for apple and pear growers, with uncontrolled infestations causing significant damage to these crops. The model results are used to determine a possible control strategy. Analysis of the model reveals that release of sterile moths is most efficient if it can be done downwind of the orchard, and that control of moth damage might be enhanced by surrounding individual orchards with a row or two of non-pome fruit trees.
