The Glassy-winged Sharpshooter (GWSS) is an invasive species that is threatening the California grape industry. GWSS live on many different hosts. However, they vector Pierce's Disease in grapes which can kill a grape vine in within 2 years, depending on variety susceptibility. Direct observations and sticky trap data was collected from a pilot study area consisting of 3600 acres of citrus, 3100 acres of grapes, and 1700 acres of other perennial host including almond, blueberries, cherries, nectarines, peaches, and pistachios. Yellow sticky traps were placed throughout the area in a ¼ mile grid and serviced weekly. Direct observations were made on a monthly cycle with all citrus orchards being sampled at a rate of 10 observations per 40 acres.
