Asian Longhorned Beetle 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 Asian longhorned beetle (Anoplophora glabripennis) at 689.75F growing degree days (base 50F, start date: January 1, double sine 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). As a generalist pest, Asian longhorned beetle poses a great potential threat to eastern forests. For all inquiries regarding this dataset, please contact the USA-NPN.

物候预测图（Pheno Forecast）可针对多类物种的关键生命周期阶段开展预测，以优化物种保护与管理成效。针对昆虫害虫类群，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。此类关键节点通常对应管理措施实施效果最优的生命周期阶段。该类图件每日更新，可提供未来6天的预测结果。我们针对星天牛（Anoplophora glabripennis）的成虫羽化阶段进行预测，其触发阈值为689.75华氏度生长度日（基线温度50华氏度，起始日期为1月1日，采用双正弦生长度日计算法）。当前年度及上一年度的预测结果可通过美国国家物候网（USA-NPN）可视化工具（https://www.usanpn.org/data/visualizations）获取，2016年至今的预测数据则可通过美国国家物候地理网络服务获取（需申请）。作为广食性害虫，星天牛对美国东部森林构成显著潜在威胁。若需咨询该数据集相关事宜，请联系美国国家物候网。本数据需遵守美国国家物候网的数据使用政策。
