• Abstract: Common weed species can harbor Xylella fastidiosa (Xf) and its insect vectors. Should weed control be part of a Pierces disease control program? To address this question, we will survey weed species in agricultural areas known to host Xf, and determine the level of insect vector activity and the proportion of potential vectors that carry Xf. In the laboratory, we will compare three techniques to detect Xf in insects. Current methods produce mixed results; assessment of each methods accuracy will improve comparison of research projects and field survey results. This project will provide information for control decisions by investigating the importance of vegetation management in reduction of insect populations and inoculum potential.
