Homalodisca vitripennis (Germar) (Formerly known as Homalodisca coagulata) (Takiya et al. 2006)
Glassy-winged sharpshooter (GWSS), xylophagous leafhopper
Southeastern U.S. (Hoddle et al. 2003)
Introduced to California by 1990 (Blua et al. 1999)
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)

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.
