The Glassy-winged sharpshooter is a serious agricultural pest in California. When feeding, it can transmit Pierce's Disease to grapevines, and other diseases to almond trees, alfalfa, and oleanders. First identified in the State in 1990, this insect has spread throughout Southern California and into the Southern San Joaquin Valley.  In 2001, the Glassy-winged sharpshooter was discovered in Santa Clara County for the first time.  Currently, the Glassy-winged sharpshooter is found in three residential areas in Santa Clara County.  Through exclusion activities, pesticide treatments, and the release of natural enemies, we hope to control the spread of this pest.
