Glassy-Winged Sharpshooter
Scientific Name:
Homalodisca vitripennis (Germar) (Formerly known as Homalodisca coagulata) (Takiya et al. 2006)
Common Name:
Glassy-winged sharpshooter (GWSS), xylophagous leafhopper
Glassy-winged sharpshooter on a grape leaf - Peggy Greb USDA, Agricultural Research Service


  • USDA. ARS. Tellus.

    Rodrigo Krugner, an entomologist with the Agricultural Research Service (ARS) in Parlier, California, has found an innovative way to control insect pests in California vineyards: tapping into the vibrational signals they use as mating calls.

    Krugner’s efforts have mainly focused on glassy-winged sharpshooters, which spread a bacterium that causes Pierce’s disease in vineyards and costs the California grape industry an estimated $104 million a year. Growers use chemical sprays to control the pests, but insecticides also kill beneficial insects, leave residues, and become less effective as the insects develop resistance.

Native To:
Southeastern U.S. (Hoddle et al. 2003)
Date of U.S. Introduction:
Introduced to California by 1990 (Blua et al. 1999)
Means of Introduction:
Probably arrived in California on nursery stock from the southeastern U.S. (Blua et al. 1999)
Vector of Pierce's disease (lethal disease of grapevines) (Blua et al. 1999)
