The spotted lanternfly Lycorma delicatula (White) is an invasive insect spreading throughout southeast Asia and eastern North America. The rapid spread of this species is facilitated by the prevalence of its preferred host, tree of heaven (Ailanthus altissima (Mill.) Swingle), as well as its use of many other host plants. While the spotted lanternfly has been previously reported to use over 65 plant species, most of these reports are from Asia and may not be applicable in North America. Additionally, many of the known hosts have not been specified as feeding hosts or as egg laying substrates. To better understand the potential impacts of this invasive insect on natural and cultivated systems in North America, we reviewed records from published and unpublished results and observations of host plant use by spotted lanternfly. We aggregated 172 host plant records worldwide and found feeding behaviors associated with 103 plant taxa across 33 families and 17 orders, 20 of which were not previously known to be associated with SLF and 15 of which were not confirmed as feeding hosts. North American records account for 56 of these taxa which include native, cultivated, and nonnative species. As a result, the spotted lanternfly has the potential to impact a wide assortment of ecosystems throughout its potential range and its North American distribution may not be limited by the presence of tree of heaven.

世界范围内的斑点灯笼蝇寄主植物，来自北美的重要补充

斑点灯笼蝇 Lycorma delicatula (White) 是一种入侵性昆虫，分布于东南亚和北美东部。该物种的快速传播得益于其首选寄主天堂之树（臭椿（Mill.）Swingle）的流行以及它对许多其他寄主植物的使用。虽然之前有报道称斑点灯笼蝇使用了超过 65 种植物，但这些报告中的大部分来自亚洲，可能不适用于北美。此外，许多已知的宿主尚未被指定为摄食宿主或产卵基质。为了更好地了解这种入侵昆虫对北美自然和栽培系统的潜在影响，我们审查了已发表和未发表的结果记录以及斑点灯笼蝇使用寄主植物的观察结果。我们汇总了全球 172 种寄主植物记录，发现与 33 个科和 17 个目中的 103 个植物分类群相关的摄食行为，其中 20 个以前未知与 SLF 相关，其中 15 个未被确认为摄食宿主。北美记录占这些分类群中的 56 个，其中包括本地、栽培和非本地物种。因此，斑点灯笼蝇有可能在其潜在范围内影响各种各样的生态系统，其北美分布可能不受天堂树存在的限制。北美记录占这些分类群中的 56 个，其中包括本地、栽培和非本地物种。因此，斑点灯笼蝇有可能在其潜在范围内影响各种各样的生态系统，其北美分布可能不受天堂树存在的限制。北美记录占这些分类群中的 56 个，其中包括本地、栽培和非本地物种。因此，斑点灯笼蝇有可能在其潜在范围内影响各种各样的生态系统，其北美分布可能不受天堂树存在的限制。
