The glassy-winged sharpshooter (Homalodisca coagulata) has been detected in a Sierra Vista, Arizona nursery. This insect is the primary vector of an incurable disease of grapes, called Pierce's disease (Xylella fastidiosa). The specimens found in Sierra Vista have not yet been tested for the presence of Pierce's disease. The glassy-winged sharpshooter is native to the southeastern United States and can fly up to a quarter mile. Since the first detection in late August nearly 1,000 traps have been set around the region. Pierce's disease devastated Southern California vineyards in the late 1990's and is undoubtedly raising concern with Arizona grape growers now that the vector has been detected.
