Interpretive Summary: 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), a pest of soybeans, peanuts, and alfalfa in the southern United States, was recently shown to be a vector of Grapevine red blotch virus (GRBV) in a greenhouse study. Feeding and reproductive status of ten weed and ten 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. Knowledge of plant species present in vineyards that serve as alternative hosts for S. festinus will be important in developing management strategies to mitigate virus spread.
