Lilac Borer Pheno Forecast, Contiguous United States, Current Year and Prior Year

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. Adult lilac borers overwinter in the heartwood of trees, then emerge in early summer. Certain control measures are most effective when adults emerge.We forecast adult emergence in lilac borer (Podosesia syringae) at 500-1300F growing degree days (base 50F, start date: January 1, double sine GDD method). These maps are updated daily and available 6 days in the future. Forecasts are available for the current and prior year in the USA-NPN Visualization Tool (https://www.usanpn.org/data/visualizations).For all inquiries regarding this dataset, please contact the USA-NPN.

Pheno Forecast地图通过预测多种物种的关键生命周期阶段，以优化保护和管理效果。针对昆虫害虫物种，Pheno Forecast基于物种生命周期关键点的已发布生长度日（GDD）阈值。这些关键点通常代表管理行动最为有效的生命周期阶段。成年丁香蠹在树木的心材中越冬，然后在初夏时节出土。当成年虫出现时，某些控制措施最为有效。我们预测丁香蠹（Podosesia syringae）成虫的出土时间，基于500-1300F的生长度日（基准50F，起始日期：1月1日，双正弦GDD方法）。这些地图每日更新，并可提供未来6天的预测。预测数据可供当前年份及上一年份在美国国家公园保护网络可视化工具（https://www.usanpn.org/data/visualizations）中查阅。有关此数据集的所有查询，请与美国国家公园保护网络联系。此数据受美国国家公园保护网络数据使用政策的约束。
