Likelihood of Establishment Map
A Likelihood of Establishment map is now available. This survey should only be considered in the states with appropriate weather conditions and suitable hosts for this insect. The map was produced by the SAFARIS Team. SAFARIS is a modeling framework that enables PPQ to quickly respond to emergencies, efficiently survey for pests, and assess potential pest impacts by collecting critical geospatial data and developing predictive models. SAFARIS is developed and maintained by the NC State University, Center for Integrated Pest Management (CIPM) with support from PPQ PPRA.
