A new population of the Asian longhorned beetle (Anoplophora glabripennis Motschulsky), an invasive species in North America since 1996, was discovered in Charleston County, South Carolina, in 2020. This population is the furthest south Asian longhorned beetle has established in North America. Previous models only estimate development time at this latitude; as such, we examined Asian longhorned beetle phenology in this novel climate. Over 24 consecutive months, we collected 153 eggs, 878 larvae, 37 pupae, and 1 unemerged adult (1,009 total specimens) from the federal quarantine zone in South Carolina and used larval head capsule width to determine development rate and voltinism. The presence of Asian longhorned beetle adults was determined via visual field observations. Asian longhorned beetle in South Carolina appears to have a synchronous univoltine life cycle, in contrast to populations in the northern United States and Canada that typically develop in 2-3 yr. This information will be useful for future model development to determine Asian longhorned beetle life cycles, for implementing novel management methods, and will aid in predictions to benefit visual survey efficacy.
亚洲长角天牛（Anoplophora glabripennis Motschulsky）自1996年起成为北美洲的入侵物种，2020年在南卡罗来纳州查尔斯顿县发现了一个新的种群。该种群是亚洲长角天牛在北美洲最南端建立的种群。之前的模型仅估计了在这个纬度的发育时间；因此，我们在这种新的气候条件下研究了亚洲长角天牛的物候。在连续24个月的时间里，我们从南卡罗来纳州的联邦检疫区收集了153枚卵、878只幼虫、37个蛹和1只未羽化的成虫（共1009个标本），并使用幼虫头壳宽度来确定发育速率和化性。通过视野观察确定亚洲长角天牛成虫的存在情况。与美国北部和加拿大的种群通常需要2至3年才能发育成熟不同，南卡罗来纳州的亚洲长角天牛似乎具有同步的一化性生命周期。这些信息将有助于未来确定亚洲长角天牛生命周期的模型开发、实施新的管理方法，并有助于提高目视调查效果的预测。
