The glassy-winged sharpshooter (GWSS) was inadvertently introduced in to California from the southeastern U.S. It is a vector of the bacterium that causes Pierce's disease of grape. About 20-30% of the grapes in the Temecula Valley in southern California have been removed due to Pierce's disease. Efforts to develop a more reliable trapping system in grapes and citrus in southern California will be presented in this poster. The trap predominantly used by agencies in California to monitor GWSS is the Pherocon AM trap, which was originally developed for the apple maggot. The reliability of the AM trap is in question especially when GWSS populations are low. Furthermore, the relationships of the number of GWSS caught with oviposition and feeding are currently unknown.
