Rearing of Spissistilus festinus [Say, 1830] (Hemiptera: Membracidae) on snap bean to facilitate studies on the transmission biology of grapevine red blotch virus.

ABSTRACT: Spissistilus festinus [Say, 1830] (Hemiptera: Membracidae) is a well-known pest of leguminous crops and a more recently described pest of grapevine due to its ability to transmit grapevine red blotch virus, an economic threat to grape production. Legumes (family Fabaceae), unlike grapevines (Vitis vinifera L.), are preferred feeding and reproductive hosts for S. festinus. Here, we analyzed the development and behavior of S. festinus on snap beans (Phaseolus vulgaris) in comparison to alfalfa (Medicago sativa) and grapevines, with an emphasis on colony establishment and population growth. Snap beans supported all stages of S. festinus development, promoting feeding, reproduction, and colony establishment, as well as supporting a faster life cycle, particularly on detached trifoliates in con
