Abstract The problem of invasive species spread requires timely analysis the biological dynamics that lead to spatial dispersion. Here, a dynamic model captures behavior recently introduced emerald ash borer (EAB) ( Agrilus planipennis ) and its impacts on host Fraxinus spp.) trees. Parasite–host system are extended spatially using Spatial Modeling Environment. resulting can serve as repository for changing knowledge about EAB biology behavior. Studies rapid infestation in Michigan used inform simulations DuPage County, Illinois, USA. We use geographic information create heterogeneous landscapes test alternative policy scenarios. effectiveness three suppression scenarios: eradication strategy, firewood quarantines, tree thinning. Simulations demonstrate accelerates with degraded capacity, results pointing quarantines most effective solution. Copyright © 2006 John Wiley & Sons, Ltd.
