As Lycorma delicatula (White) continues to spread across the United States, more winegrapes are potentially susceptible to damage from this pest. Lycorma delicatula, spotted lanternfly, is primarily associated with Ailanthus altissima (Mill.) Swingle, a tree from its native range that is now globally distributed. While L. delicatula is a known pest of cultivated Vitis spp. in South Korea, its relationship with the specific grape species grown in the United States is unclear. This study assessed L. delicatula survivorship and development on 5 Vitis species, including 2 winegrape V. vinifera L. varieties, ‘Pinot Noir’ and ‘Chardonnay’, Concord grape, Vitis labrusca L., River grape, Vitis riparia Michx., and muscadine grape, Vitis rotundifolia Michx. var. ‘Carlos’. A diet of A. altissima served as a positive control. Lycorma delicatula provided with a diet of V. riparia or V. vinifera ‘Pinot Noir’ yielded the highest survivorship and fastest rates of development among grape diets and were statistically equivalent to those provided with A. altissima. Vitis rotundifolia did not support L. delicatula growth past the third-instar life stage, indicating this species is a poor host for the early development of this pest. Our results indicate that both V. riparia and V. vinifera are favorable hosts for L. delicatula and may provide the means for this insect to invade and establish in new regions.

Lycorma delicatula（半翅目：Fulgoridae）在栽培和本地葡萄属植物上的发育和存活。（维塔目：葡萄科）美国东部

随着 Lycorma delicatula（白色）继续在美国蔓延，更多的酿酒葡萄可能容易受到这种害虫的损害。Lycorma delicatula（斑点灯笼蝇）主要与臭椿（Ailanthus altissima (Mill.) Swingle）有关，这是一种来自其原生地的树，现已分布在全球。而 L. delicatula 是栽培葡萄属的一种已知害虫。在韩国，它与美国种植的特定葡萄品种的关系尚不清楚。本研究评估了 L. delicatula 在 5 个葡萄品种上的存活和发育，包括 2 个酿酒葡萄品种“黑皮诺”和“霞多丽”、康科德葡萄、Vitis labrusca L.、河葡萄、Vitis riparia Michx. 和圆叶葡萄，Vitis rotundifolia Michx。变种 “卡洛斯”。臭蒿饮食作为阳性对照。在葡萄饲料中，以 V. riparia 或 V. vinifera ‘Pinot Noir’ 饲料喂养的 Lycorma delicatula 具有最高的存活率和最快的发育速度，并且在统计上与以 A. altissima 饲料喂养的结果相当。Vitis rotundifolia 不支持 L. delicatula 生长超过第三龄生命阶段，表明该物种对于这种害虫的早期发育来说是一个不良宿主。我们的结果表明，V. riparia 和 V. vinifera 都是 L. delicatula 的有利宿主，并可能为这种昆虫入侵并在新地区定居提供手段。
