The invasive spotted lanternfly, Lycorma delicatula White (Hemiptera: Fulgoridae), is a destructive phloem feeder with a broad host range that appears to narrow as they reach the adult stage. Little is known about how this invasive insect disperses among host plants or how far they may move to reach them. Here, we measured vertical climbing and horizontal jumping capacity and evaluated the effect of fluorescent marking powders on mobility and survivorship of L. delicatula nymphs and adults. All nymphal instars climbed significantly longer vertical distances compared with adults, whereas early adults (pre‐oviposition period) jumped longer horizontal distances compared with nymphs or late adults (oviposition period) based on single jump measurements. Marking nymphs and adults with fluorescent powder had no significant effect on vertical or horizontal movement and did not affect the survivorship of nymphs or adults. Our results indicate that L. delicatula nymphs can easily move among host plants, and that marking L. delicatula nymphs and adults with florescent powder serves as an acceptable means to measure their dispersal in the environment.

水平和垂直分散能力以及荧光标记对Dycorma delicatula若虫和成虫的影响

具侵入性的斑点灯笼蝇Lycorma delicatula White（半翅目：Fulgoridae）是一种破坏性的韧皮部喂食器，其寄主范围很广，到成年阶段似乎会变窄。对于这种侵入性昆虫如​​何在寄主植物中传播或它们移动到到达寄主植物的距离了解甚少。在这里，我们测量了垂直爬升和水平跳升的能力，并评估了荧光标记粉对小L. delicatula迁移和存活的影响若虫和成人。根据单跳测量，与若虫或成年后期（产卵期）相比，所有若虫幼虫的垂直距离都比成年长得多，而早成虫（产卵前期）的水平距离远大于成虫或成年后期（产卵期）。若虫和成虫用荧光粉标记对垂直或水平运动没有显着影响，也不影响若虫或成虫的存活。我们的结果表明，纤毛乳杆菌若虫可以在寄主植物之间轻松移动，并且用荧光粉标记纤毛乳虫和成虫是衡量其在环境中传播的可接受方法。
