Bronze Birch Borer Pheno Forecast, Contiguous United States, 2016 - Current 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. These maps are updated daily and
available 6 days in the future. We forecast adult emergence in bronze
birch borer (Agrilus anxius) at 450F growing degree days (base 50F, start date: January 1,
double sine GDD method). Forecasts are available for the current and prior year in the the USA-NPN Visualization Tool (https://www.usanpn.org/data/visualizations) and 2016-present through USA-NPN Geo Web Services (available upon request). Bronze birch borer frequently kills birch
trees by boring into the wood.For all inquiries regarding this dataset, please contact the USA-NPN. This data is subject to the USA-NPN's Data Use Policy.

Pheno Forecast映射技术能够预测多种物种的关键生命周期阶段，以优化 Conservation 和 Management 的成果。针对昆虫害虫物种，Pheno Forecast的构建基于已发表的物种生命周期关键点的生长度日（GDD）阈值。这些关键点通常代表着生命周期阶段，在此阶段采取的管理措施最为有效。此类地图每日更新，并可供未来6天使用。以青铜桦树蠹（Agrilus anxius）为例，我们基于450F生长度日（基准50F，起始日期：1月1日，采用双正弦GDD方法）预测成虫的出现。当前年份及之前年份的预测数据可通过USA-NPN可视化工具（https://www.usanpn.org/data/visualizations）获取，而2016年至今的数据则可通过USA-NPN地理网络服务（需请求提供）获得。青铜桦树蠹通过钻入木质部来杀害桦树。关于此数据集的所有咨询，请与USA-NPN联系。本数据受USA-NPN数据使用政策的约束。
