Bagworm 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 bagworm (<i>Thyridopteryx ephemeraeformis</i>) at 600-900F growing
degree days (base 50F, start date: March 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). Bagworm caterpillars defoliate over 50 families of evergreen and
deciduous trees and shrubs, primarily arborvitae, juniper, pine, and
spruce.<br><br><i>For all inquiries regarding this dataset, please contact the USA-NPN. This data is subject to the USA-NPN's Data Use Policy.</i>

物候预测地图（Pheno Forecast maps）可预测多种物种的关键生命周期阶段，以提升保护与管理成效。对于害虫物种，物候预测基于已发表的物种生命周期关键节点的生长度日（growing degree day, GDD）阈值。这些关键节点通常代表管理措施最有效的生命周期阶段。这些地图每日更新，且可提供未来6天的预测结果。我们预测袋蛾（<i>Thyridopteryx ephemeraeformis</i>）幼虫的羽化时间为600-900华氏度生长度日（基准温度50华氏度，起始日期：3月1日，采用简单平均GDD计算方法）。预测结果可通过USA-NPN可视化工具（https://www.usanpn.org/data/visualizations）获取当前及上一年度的数据，2016年至今的数据则可通过USA-NPN地理网络服务（需申请获取）获取。袋蛾幼虫会使50多个科的常绿及落叶树木与灌木落叶，主要包括侧柏、刺柏、松树和云杉。<br><br><i>有关本数据集的所有咨询，请联系USA-NPN。本数据受USA-NPN数据使用政策约束。</i>
