(Blessig) is a serious trunk borer of oak species, currently widespread only in eastern Asia. A better understanding of the invasive potential of this borer across other distribution-free areas is further needed to prevent its invasion and outbreaks. In this study, we mapped the current distribution of , two susceptible hosts ( and ) and all 11 host species of this borer, and then modeled their potential distributions. We comprehensively compared the current distributions and potential invasion ranges among , susceptible hosts and all hosts to select areas at risk for the establishment of this borer. MaxEnt model predictions revealed that (1) the central and eastern US, a small area of central and western Europe, western Georgia, and central Argentina had suitable climates for . Such highly suitable areas for this borer overlapped considerably with the current plantation and potential distributions of its hosts. Consequently, susceptible hosts and climate suitability together create the highest risk for establishment and outbreaks, throughout central and eastern America, a small area of central Europe, western Norway and western Georgia, and (2) the broad host suitability across six continents creates a situation favorable for the colonization of this borer, further extending the spatial scale of possible infestation by worldwide.
（布莱西格小蠹）是橡树种类的一种严重的主干蛀虫，目前仅在东亚广泛分布。为防止其入侵和爆发，还需要进一步深入了解这种蛀虫在其他无分布地区的入侵潜力。在本研究中，我们绘制了布莱西格小蠹、两种易感寄主（栓皮栎和麻栎）以及该蛀虫所有11种寄主的当前分布，然后对它们的潜在分布进行了建模。我们全面比较了布莱西格小蠹、易感寄主和所有寄主之间的当前分布和潜在入侵范围，以确定该蛀虫可能定殖的风险区域。最大熵模型预测显示：（1）美国中部和东部、欧洲中西部的一小片区域、格鲁吉亚西部以及阿根廷中部具有适合布莱西格小蠹生存的气候。这种对该蛀虫高度适宜的区域与其寄主当前的种植区域和潜在分布有相当大的重叠。因此，易感寄主和气候适宜性共同在整个美国中部和东部、中欧的一小片区域、挪威西部和格鲁吉亚西部为布莱西格小蠹的定殖和爆发创造了最高风险；（2）这种蛀虫在六大洲广泛的寄主适宜性创造了有利于其定殖的条件，进一步扩大了布莱西格小蠹在全球可能侵染的空间范围。
