Abstract

Grapevine red blotch virus (GRBV) currently poses a serious threat to the wine industry. The three-cornered alfalfa hopper (3CAH), Spissistilus festinus (Say) (Hemiptera: Membracidae), was recently shown in a greenhouse study to be a vector of GRBV in grapes. Feeding and reproductive status of 10 weed and 10 cover crop species commonly found in grape vineyards were evaluated in no-choice tests. Species confirmed as reproductive hosts were subsequently evaluated in choice tests to determine S. festinus oviposition preference. Spanish clover, dandelion, birdsfoot trefoil, common groundsel, field bindweed, magnus peas, bell beans, blando brome, purple vetch, black medick, subterranean clover, crimson clover, and woollypod vetch were all found to be reproductive hosts. The plant species that exhibited the greatest nymph emergence in each of the three groups tested for preference were all in the family Fabaceae. Knowledge of plant species present in vineyards that serve as alternative hosts for S. festinus can contribute to developing management strategies to mitigate virus spread.

摘要

葡萄红斑点病毒（GRBV）目前对葡萄酒行业构成严重威胁。在一项温室研究中，最近发现三角苜蓿叶蝉（3CAH），即Festinus Spissistilus（Say）（半翅目：角蝉科），是葡萄中GRBV的传播媒介。在无选择试验中评估了葡萄园常见的10种杂草和10种覆盖作物的取食和繁殖状况。随后在选择试验中对被确认为繁殖宿主的物种进行评估，以确定Festinus Spissistilus的产卵偏好。发现西班牙三叶草、蒲公英、鸟足豆、普通千里光、田旋花、马格努斯豌豆、钟豆、布氏雀麦、紫巢菜、黑麦草、地下三叶草、绛三叶和毛荚巢菜均为繁殖宿主。在偏好测试的三组中，若虫出现率最高的植物物种均属于豆科。了解葡萄园中作为Festinus Spissistilus替代宿主的植物物种，有助于制定管理策略以减轻病毒传播。
