Lycorma delicatula White (spotted lanternfly; SLF) is an invasive pest insect threatening increased agricultural costs as it spreads rapidly westward across the United States. As such, surveying was conducted adjacent to the insect's westernmost quarantine area in 2021-2022 to support multi-state monitoring. Specifically, 2,077 visual and sticky-trap surveys were performed in 13 repeatedly surveyed plots strategically located near high-traffic roadways and rail-lines along the Ohio-West Virginia border. Sites were located in Jefferson (Ohio), Brooke (West Virginia), and Hancock (West Virginia) counties. Only one SLF was detected in 2021 (the third documented Ohio site containing SLF) in close proximity to a railway, consistent with rail-mediated dispersal trends recorded throughout the United States. Thirty-one SLF were captured in 2 Ohio sites in 2022, 30 of which were captured at the same railway site as in 2021. However, 1 of the 31 SLF was found in a plot on a university campus 1.25 km from the nearest railway, along with 10 additional specimens found in a follow-up visual survey of a neighboring woodlot. Failure to detect SLF at nearby survey plots nearer to the closest rail line and commuter parking lots suggests local unaided dispersal in a state with primarily train-mediated dispersal-mirroring trends in affected states with more established SLF populations. Data from this survey are valuable for establishing baselines and early-invasion patterns of SLF dispersal into Ohio, anticipating SLF expansion patterns in Ohio, and eventually contributing to improved SLF dispersal modeling in Ohio, the Midwest, and the United States.
斑衣蜡蝉（Lycorma delicatula White，简称SLF）是一种入侵性害虫，随着它在美国迅速向西蔓延，威胁着农业成本的增加。因此，在2021年至2022年期间，在该昆虫最西部的检疫区附近进行了调查，以支持多州监测。具体而言，在俄亥俄州与西弗吉尼亚州边境沿线交通繁忙的道路和铁路线附近的13个重复调查地块上，进行了2077次目视和粘虫板调查。这些地点位于杰斐逊县（俄亥俄州）、布鲁克县（西弗吉尼亚州）和汉考克县（西弗吉尼亚州）。2021年只发现了一只斑衣蜡蝉（这是俄亥俄州有记录的第三个发现斑衣蜡蝉的地点），靠近一条铁路，这与美国各地记录的铁路介导的扩散趋势一致。2022年在俄亥俄州的两个地点捕获了31只斑衣蜡蝉，其中30只与2021年在同一个铁路地点捕获。然而，在31只斑衣蜡蝉中有1只在距离最近铁路1.25公里的大学校园地块中被发现，在对附近林地的后续目视调查中还发现了另外10只标本。在距离最近铁路线和通勤停车场更近的附近调查地块未检测到斑衣蜡蝉，这表明在一个主要以火车介导扩散的州存在局部自主扩散，这与受斑衣蜡蝉影响更严重、种群更稳定的州的扩散趋势相似。这项调查的数据对于建立斑衣蜡蝉扩散到俄亥俄州的基线和早期入侵模式、预测俄亥俄州斑衣蜡蝉的扩散模式以及最终有助于改进俄亥俄州、中西部地区和美国的斑衣蜡蝉扩散模型具有重要价值。
