Subsections found in Results
- Actual SPB Infestation Levels: 1987 to 2005 : Total numbers of SPB spots detected in 16 States in the Southeastern United States for the period 1987-2005 are shown.
- Overall Prediction Accuracy at the State Level, Based on State Averages 1987-2005 : Over the 19-year period (1987-2005), 245 State-level predictions of SPB infestation trend and population level were made by averaging the mean SPB per trap per day and percent SPB for all locations monitored within each State for each year of participation in the Southwide survey.
- Accuracy of Predictions for Individual States, Based on State Averages: 1987 - 2005 : Accuracy of SPB predictions at the State level for individual States for the period 1987-2005, determined by averaging data for all counties and ranger districts surveyed within the given State for a given year, is shown.
- Accuracy of Predictions at the State Level: 1987-1998 versus 1999-2005 : We summarized State-level predictions for 12 States for the periods 1987-1998 and 1999-2005.
