American sweetgum (Altingiaceae) was first introduced to China over 60 years ago. It is an important tree species for increasing landscape value and promoting afforestation in urbanized areas of eastern China in the past 20 years. Sweetgum inscriber (Coleoptera: Curculionidae) is a local bark beetle pest and lethal to the introduced American sweetgum. To provide preliminary estimates of the potential economic losses caused by the sweetgum inscriber, a field investigation was conducted to survey the beetles' natural distribution in China. Based on field collections, potential distribution was predicted using Maxent. All nurseries stocking American sweetgum were in the high and very high suitability area of sweetgum inscriber. Additionally, we employed a model of direct loss incorporating tree and removal cost. A questionnaire was sent to maintenance companies, growers, and gardener associations for tree removal prices. We estimated the removal cost of each tree. In addition, the market price and inventory were also gained from telephone interview. Our economic analysis indicates that if sweetgum inscriber were to become established in the main American sweetgum business, the potential losses of nursery stock and urban area could range from USD 12.81 to 14.41 million.
美国枫香（金缕梅科）于60多年前首次引入中国。在过去20年里，它是中国东部城市化地区提高景观价值和促进造林的重要树种。枫香刻蚜（鞘翅目：象甲科）是一种当地的树皮甲虫害虫，对引入的美国枫香具有致死性。为了初步估计枫香刻蚜造成的潜在经济损失，进行了实地调查，以调查该甲虫在中国的自然分布。基于实地采集，使用最大熵模型预测了其潜在分布。所有种植美国枫香的苗圃都位于枫香刻蚜的高适宜性和非常高适宜性区域。此外，我们采用了一个包含树木和清除成本的直接损失模型。向维护公司、种植者和园艺协会发送了一份关于树木清除价格的问卷。我们估计了每棵树的清除成本。此外，市场价格和库存也通过电话采访获得。我们的经济分析表明，如果枫香刻蚜在主要的美国枫香业务中定殖，苗木和城市地区的潜在损失可能在1281万至1441万美元之间。
