The ability to predict how local habitat variation will affect the dispersal of invasive species is an essential tool for the efficient targeting of resources to manage the spread of an invasive species. Here we describe a coupled map lattice model for the local spread of a recently discovered devastating pest of Fraxinus spp. in North America, the Emerald Ash Borer, Agrilus planipennis. The model is based on field estimates of population growth, dispersal, larval consumption rates, and developmental thresholds and is designed to be able to incorporate site specific spatially explicit resource variation. We present the functionality of this model by using it to investigate the influence of resource distribution on the spread of A. planipennis, and the relative importance of ovipo...
