• Abstract: Pierces disease, caused by Xylella fastidiosa has become an increasingly important factor in grape production in California since 1996. The glassy-winged sharpshooter (GWSS) is a primary X. fastidiosa vector. Serious grape and vine losses have increased as GWSS numbers have increased in southern California (Blua et al. 1999). Purcell et al. (1999) suggested that diseases caused by X. fastidiosa are likely to become more prevalent with increased numbers and spread of GWSS. Management methods are urgently needed for GWSS that are economically, ecologically and socially acceptable. Cultural and biological components of developing integrated pest management (IPM) strategies need to be melded with efficacious GWSS chemical control and insecticide resistance management (IRM), and integrated crop management (ICM) inputs. In 2000, we studied GWSS adulticides in grapes (Akey et al., 2001a). Our objectives in the two-year trials (2001-2002) were to identify selective, conventional and biorational insecticides that were efficacious for control of immature and adult GWSS in citrus.
