Winter Moth 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 caterpillar emergence in winter moth (Operophtera
brumata) at 20-350F growing degree days (base 50F, start date: January
1, simple average GDD method). Forecasts are available for the current and prior year in the USA-NPN Visualization Tool (https://www.usanpn.org/data/visualizations) and 2016-present through USA-NPN Geo Web Services (available upon request). The caterpillars can defoliate certain
species of deciduous trees. Some control measures are most effective
when caterpillars emerge.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 地图预测了多种物种的关键生命周期阶段，旨在优化保护与管理成效。针对昆虫害虫物种，Pheno 预报基于物种生命周期关键节点已发表的生长期度日（GDD）阈值。这些关键节点通常代表管理措施最为有效的生命周期阶段。这些地图每日更新，并可在未来6天内获取。对于冬尺蠖（Operophtera brumata）的幼虫出现，我们基于20-350°F的生长期度日（基准温度50°F，起始日期：1月1日，简单平均GDD方法）进行预测。预报信息可在美国国家公园网络可视化工具（https://www.usanpn.org/data/visualizations）中查看当前及过往年度数据，以及2016年至今的数据，通过美国国家公园网络地理信息服务（如有需求，可申请获取）。幼虫可导致某些落叶树种叶片脱落。在幼虫出现时，某些控制措施最为有效。关于此数据集的所有查询，请联系美国国家公园网络。此数据受美国国家公园网络数据使用政策的约束。
