• Abstract: The glassy-winged sharpshooter (GWSS) is an invasive species that is threatening California agriculture. GWSS live on many different host plants, but the main concern is their potential to vector Pierces disease in grapes. Pierces disease can kill susceptible grape vines within 2 years after infection (Varela et al. 2001). An area-wide management program is underway in Kern County to manage outbreak populations of GWSS and slow their northward spread in the San Joaquin valley. To be successful, large scale regional insect management programs require an accurate assessment of pest density and distribution to provide decision support for program managers (Liebhold et al. 1993, Roberts et al. 1993). This report details program activity aimed at understanding the spatial distribution of GWSS populations in Kern County.
