• Abstract: The year 2002 marks the second of a proposed three year study to develop and demonstrate the Areawide Management of Glassy-winged Sharpshooter (GWSS) in Kern County, CA. The first year successfully demonstrated the areawide concept as a strategy that will reduce GWSS to very low population densities in a robust multi-crop perennial growing system. Critical to this success is a well organized and coordinated delivery system that growers can adapt to their present pest management programs. The strategy in 2001 was to treat citrus using an action threshold of greater than one GWSS/tree which resulted in 1830 acres out of 3600 receiving a foliar, knockdown, insecticide. All citrus received a single systemic application of Admire following the foliar treatments. All acreage, approximately 13,000 acres, is monitored utilizing a combination of direct observations and sticky traps arrayed in a mile grid. Grower interest in the results of the pilot study in 2001 culminated in a request to initiate an areawide program in Kern County. An expanded program was implemented in the county. This areawide program utilized the strategies developed in the first year of the pilot study.
