Glassy-Winged Sharpshooter Impact on Orange Yield, Fruit Size, and Quality

Prior to this study, it was unknown what impact the glassy-winged sharpshooter (GWSS), Homalodisca coagulata, had on orange yield, size, and quality as well as tree vigor. The goals of this project were to determine the usefulness of management of GWSS to prevent yield loss, fruit size reduction, and degraded fruit quality. This information is paramount before we can even begin to incorporate these into conventional IPM programs. First we needed to know what if any, impact GWSS has on citrus. Secondly we needed to know how to use the currently available materials against the GWSS in IPM programs to prevent potential losses without disrupting citrus IPM programs. Prior to this study, efforts to manage GWSS in California citrus were primarily to suppress populations to limit the spread of Xylella fastidiosa in areawide management programs.
