Anoplophora glabripennis Motschulsky, a wood borer native to Asia, was recently found in New York City and Chicago. In an attempt to eradicate these beetle populations, thousands of infested city trees have been removed. Field data from nine U.S. cities and national tree cover data were used to estimate the potential effects of A. glabripennis on urban resources through time. For the cities analyzed, the potential tree resources at risk to A. glabripennis attack based on host preferences, ranges from 12 to 61% of the city tree population, with an estimated value of $72 million-$2.3 billion per city. The corresponding canopy cover loss that would occur if all preferred host trees were killed ranges from 13-68%. The estimated maximum potential national urban impact of A. glabripennis is a loss of 34.9% of total canopy cover, 30.3% tree mortality (1.2 billion trees) and value loss of $669 billion.
光肩星天牛原产于亚洲，是一种蛀木害虫，最近在纽约市和芝加哥被发现。为了根除这些甲虫种群，数千棵受感染的城市树木已被砍伐。利用来自美国九个城市的实地数据和全国树木覆盖数据，来估计光肩星天牛随时间推移对城市资源的潜在影响。对于所分析的城市，根据寄主偏好，光肩星天牛攻击下可能面临风险的树木资源占城市树木总数的12%至61%，每个城市的估计价值为7200万美元至23亿美元。如果所有偏好的寄主树木都被杀死，相应的树冠覆盖损失将在13%至68%之间。光肩星天牛对全国城市的估计最大潜在影响是树冠覆盖总面积损失34.9%，树木死亡率30.3%（12亿棵树），价值损失6690亿美元。
