What is Pierce's Disease?

Pierce's Disease is a bacterial infection, which is spread by bugs that feed on grapevines, particularly the "glassy winged sharpshooter." Grapevines that become infected with PD can quickly become sick and die.

QUANTITATIVE ASPECTS OF THE TRANSMISSION OF XYLELLA FASTIDIOSA BY THE GLASSY-WINGED SHARPSHOOTER

  • Author(s): Bextine, Blake; Blua, Matthew; Jackson, Brian;
  • Abstract: In this report, we describe quantitative aspects of Xylella fastidiosa (Xf) transmission by the glassy-winged sharpshooter (GWSS). In previous studies, we discovered correlations between the number of Xf cells acquired by GWSS and acquisition access period, and total ingestion time on Xf sources. On the other end of the disease cycle, correlations were detected between the number of Xf cells inoculated into plant stems and the length of inoculation access periods (IAP), and the number of probes. In the study reported here, correlations between the number of cells inoculated into a plant and IAP or number of probes were consistent when the IAP was restricted to 30, 60, 90, or 120 minutes.
