Glassy-winged sharpshooter and Pierce's disease

Pierce's disease field guide

Glassy-winged sharpshooter (Homalodisca coagulata) is a serious new agricultural pest in California. When feeding, it can transmit Pierce's disease to grapevines, and other diseases to almond trees, alfalfa, citrus and oleanders. First sighted in the state in 1990, this insect has spread throughout Southern California and into the southern San Joaquin Valley.

The glassy-winged sharpshooter and the diseases it carries pose a serious threat to the California viticulture industry, as well as to other crops throughout the state.
