Overview: The discovery of the glassy-winged sharpshooter on grapevines sold at Costco stores across Northern California has raised concerns among vineyard owners, who fear that the invasive insect could spread Pierce’s disease and devastate their crops.
The Full Story
Invasive pests are a perennial problem for Northern California’s wine industry. A recent discovery of the glassy-winged sharpshooter on grapevines sold at Costco stores has raised concerns among vineyard owners, who fear that the insect could spread Pierce’s disease and devastate their crops.
The glassy-winged sharpshooter is a small but deadly insect that can infest entire vineyards. It attacks the plant’s xylem tissue, causing grapevines to yellow, dry out, shrivel and eventually die. The pest was discovered on Burchell Nursery plants sold at Costco stores between April 21 and May 21.
Sacramento County agricultural officials have issued a warning to residents who purchased grapevines or Burchell Nursery plants during that timeframe not to plant, move or throw them away. Instead, they are being asked to isolate the plants and contact their local agricultural commissioner’s office for inspection and removal.

It has been detected on grapevines in several Northern California counties, including Sacramento, Yolo, Napa, Sonoma, Marin and Solano. The pest can spread quickly through wind-borne dispersal or human transportation of infested plants.
The glassy-winged sharpshooter is a significant threat to the region’s $6 billion wine industry. Vineyard owners are concerned that the insect could devastate their crops, leading to economic losses and job cuts.
