Control of Pierce’s Disease Through Areawide Management of Glassy-Winged Sharpshooter (Hemiptera: Cicadellidae) and Roguing of Infected Grapevines

Abstract The General Beale Pilot Project serves as a case study for the use of areawide monitoring and treatment programs glassy-winged sharpshooter (GWSS), Homalodisca vitripennis (Germar), roguing grapevines infected with Xylella fastidiosa, to achieve regional management Pierce’s disease. is located in southeast Kern County, CA, contains ~2,800 ha citrus grown within approximately 50 km2. For nearly 20 yr, an average 470 traps have been used monitor GWSS populations regionally by California Department Food Agriculture, inform coordinated, treatments USDA-APHIS Areawide Treatment Program overwintering citrus. Grape growers were responsible treating their own vineyards, based on surveys provided University California. Herein, we provide history Project, broken down into six eras levels success, which incorporate data captures, pesticide use, disease incidence. We describe patterns success related coordination effective that can be grape neighboring conclude describing current future challenges management, including availability resistance, refuges, inability detect rogue vines year they become infected, sustainability voluntary rely public funding.
