The box tree moth Cydalima perspectalis (Walker, 1859) (Lepidoptera: Crambidae) is an invasive species in Europe and a serious pest of box trees (Buxus spp.). In Slovakia, Central Europe, it was first reported in 2012 within the low elevation region with a warm climate. We hypothesize that the cold mountain region of Slovakia would provide less suitable conditions for the spread of this species, indicated by no or only slight damage to box trees. Five years after C. perspectalis was first recorded in Slovakia, we assessed the probability of occurrence of the moth and the probability of damage to box trees (Buxus sempervirens) by its larvae, using temperature and altitude data as predictors. In June and July 2017, at 156 locations (towns and villages) between the altitudes of 109 and 888 m, we recorded damage and categorized the intensity of damage to box trees by C. perspectalis using a four-point scale. Box trees infested by C. perspectalis were recorded in most locations at altitudes between 110 and 400 m with the mean annual temperature varying between 10.5 and 7.9 °C. High damage to box trees was found in locations up to 340 m a.s.l. characterized by mean annual temperatures above 8.5 °C. Our results suggested high probability (>60%) of any damage to box trees for the area up to approximately 300 m a.s.l. (mean annual temperature above 8.4 °C), and high probability (>60%) of high damage for the area up to approximately 250 m a.s.l. (mean annual temperature above 9 °C). The area where damage to box trees was predicted using the altitude showed great overlap with the area predicted using the mean annual temperature. The area with the probability of any damage was only slightly larger than the area with the probability of high damage.

在斯洛伐克引入五年后的侵袭性箱形树蛾：城市栖息地对箱形树的损害风险

箱形树蛾Cydalima perspectalis（Walker，1859年）（鳞翅目：Crombidae）是欧洲的一种入侵物种，是箱形树（Buxus spp。）的一种严重害虫。在中欧斯洛伐克，2012年首次在气候温暖的低海拔地区报道了该病。我们假设斯洛伐克的寒冷山区将为该物种的传播提供较不适合的条件，这表明对盒树没有或仅有轻微的损害。五年后C. perspectalis首先被记录在斯洛伐克，我们评估了蛾和箱树木损坏的可能性发生的概率（黄杨杉）的幼虫，将温度和海拔高度数据用作预测指标。在六月，七月2017年，在109的高度和888米156点之间的位置（城镇和乡村），我们记录了伤害，并归类的损坏的强度，以盒树C. perspectalis使用四点量表。盒树通过出没C. perspectalis在海拔110至400 m的大多数位置记录到的平均年温度在10.5至7.9°C之间变化。在最高海拔340 m的地区发现了对箱树的高度破坏，其特征是年平均气温高于8.5°C。我们的结果表明，在大约300 m asl（平均年气温高于8.4°C）的区域内，对框树的任何破坏均极有可能（> 60％），而在区域上方，则有很高的可能性（> 60％）受到损害。约250 m asl（年平均气温高于9°C）。使用海拔高度来预测对框树的损害的区域与使用年平均温度来预测的区域显示出很大的重叠。具有任何损坏可能性的面积仅比具有高损坏可能性的面积稍大。
