What Is It?
Glassy-winged Sharpshooter
Homalodisca coagulata
The Glassy-Winged Sharpshooter is a serious threat to California's agriculture. The Sharpshooter is native to the southeastern United States, but was probably introduced to California around 1990. The insect currently infests most of southern California and some of Butte, Fresno, Imperial, Kern, Sacramento, Santa Barbara, Santa Clara, and Tulare counties. If you wish to see a map of California that shows infested and partially infested counties then you can go to CDFA's Glassy-Winged Sharpshooter Distribution Page. In the partially infested counties eradication measures are being taken. In southern California limited releases of a particular wasp in the genus Gonatocerus is being used to help control the populations of the Sharpshooter. This wasp will parasitize only 10 - 50% of the eggs of the Sharpshooter during the first egg laying season, but it can kill up to 100% of the second generation.
