The spotted lanternfly (SLF), Lycorma delicatula (Hemiptera: Fulgoridae), has the potential to become a global pest and is currently expanding its range in the United States. In this study, we investigated the dispersal patterns of SLF in Ailanthus altissima during its oviposition period in South Korea using a fluorescent marking system. Oviposition patterns of SLF were then analyzed by surveying egg masses in A. altissima patches. The recapture rate of fluorescent-marked SLF rapidly decreased to 30% within the first two weeks. During the oviposition period, seven cases of among-patch dispersal of SLF adults were observed. The minimum distance that SLF could have traveled to achieve these among-patch dispersal events ranged from 10 to 1740 m, with most events spanning under 60 m. Also, the number of A. altissima trees on which fluorescent marked SLF were detected increased until September. Based on the egg mass survey, a total of 159 egg masses were detected from 38 out of 247 A. altissima trees. Furthermore, 79.2% of egg masses were located < 2.5 m above the ground. Finally, a generalized linear mixed model showed that tree height and diameter at root collar (DRC) of A. altissima trees had significant effects on the number of egg masses.
斑衣蜡蝉（SLF），Lycorma delicatula（半翅目：蝉科），有可能成为一种全球性害虫，目前正在美国扩大其分布范围。在这项研究中，我们使用荧光标记系统调查了 SLF 在韩国 Ailanthus altissima 产卵期间的扩散模式。然后通过调查 A. altissima 斑块中的卵块来分析 SLF 的产卵模式。标记有荧光的 SLF 的回收率在最初的两周内迅速下降到 30%。在产卵期间，观察到了 7 例 SLF 成虫的斑块间扩散。SLF 能够进行这些斑块间扩散的最小距离范围从 10 到 1740 米，大多数事件在 60 米以下。此外，到 9 月，检测到带有荧光标记的 SLF 的 A. altissima 树的数量增加。根据卵块调查，从 247 棵 A. altissima 树中的 38 棵树上共检测到 159 个卵块。此外，79.2%的卵块位于离地面<2.5 米的地方。最后，广义线性混合模型显示，A. altissima 树的树高和根颈直径（DRC）对卵块数量有显著影响。
