GPFS predictions of potential population index of oriental fruit fly, Bactrocera dorsalis, in the United States based on A. Real-Time Mesoscale Analysis weather data (2007–2012) with a 5 km resolution. The predictions are on a scale of 0-1 and do not account for the presence or absence of suitable hosts. The map is the final population index in December 2012 that resulted from the simulation of population change beginning with an initial population in January 2007. The map also includes the cold exclusion from Figure 2.
