Lack of Vertical Transmission of Grapevine Red Blotch Virus by and Sex-Associated Differences in Horizontal Transmission.

Grapevine red blotch is an emerging disease that threatens vineyard productions in North America. Grapevine red blotch virus (GRBV, species , genus , family ), the causal agent of red blotch disease, is transmitted by (Hemiptera: Membracidae) in a circulative, non-propagative mode. To gain new insight into GRBV- interactions, we delved into vertical transmission and documented a lack of transovarial transmission.

Assessing the Potential of (Hemiptera: Membracidae) from Northern California Vineyards as Vector Candidates of Grapevine Red Blotch Virus.

Ceresini treehoppers are present in northern California vineyard ecosystems, including the closely related and (Hemiptera: Membracidae). These membracids are not direct pests of wine grapes, but is a vector of grapevine red blotch virus (GRBV). No information is available on the ability of spp.
