Pheno Forecast maps predict key life cycle stages in a range of species to improve conservation and management outcomes. For insect pest species, Pheno Forecasts are based on published growing degree day (GDD) thresholds for key points in species life cycles. These key points typically represent life cycle stages when management actions are most effective. These maps are updated daily and available 6 days in the future. We forecast adult emergence in emerald ash borer (Agrilus planipennis) at 450-1500F growing degree days (base 50F, start date: January 1, double sine GDD method). This forecast was generated from February 2016 through March 2023, as a formatted version of the USA-NPN Accumulated Growing Degree Day product, and made available via the Visualization Tool and the USA-NPN website. It has been replaced by an enhanced forecast, the Emerald Ash Borer Adult and Egg Hatch Forecast, 2023 to present.
