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.

FATE OF XYLELLA FASTIDIOSA IN THE FOREGUT OF GLASSY-WINGED SHARPSHOOTERS FED ON TWO HOST PLANTS

  • Author(s): Miller, Thomas; Ramirez, Jose; Lampe, David; Lauzon, Carol; Perring, Thomas;
  • Abstract: Here we test to see the influence that feeding on citrus might have on the infection rate in an adult glassy-winged sharpshooter (GWSS) population that has been pre-exposed to Xylella fastidiosa (Xf). A GWSS population that was pre-exposed to Xf-infected grapevines remained infective for at least 12 days after feeding in either grapevines or citrus host plants. Infection rate was about 65% in the population of sampled GWSS after 12 days with no differences between the groups feeding on citrus or grapevines.
