The Virginia creeper leafhopper has been found in vineyards from the Oregon border to the northern Sacramento Valley, but so far has not made its way to the storied vineyards of Napa or Sonoma counties, according to an article in The Grower.
Reporter Vicky Boyd based the article on a report by Lucia Varela, UC Cooperative Extension advisor, an integrated pest management expert for the north coast of California. So far, the Virginia creeper leafhopper has been reported primarily in backyard and organic vineyards.
Western leafhoppers are common in California vineyards. Many are controlled by natural enemies. Whether the same will hold true for the Virginia creeper leafhoppers is unknown.
