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.

POPULATION DYNAMICS AND INTERACTIONS BETWEEN THE GLASSY-WINGED SHARPSHOOTER AND ITS HOST PLANTS IN RESPONSE TO CALIFORNIA PHENOLOGY

  • Author(s): Andersen, Peter; Mizell, Russell; Oevering, Pascal; Phillip, Phil; Coviella, Carlos; Triapitsyn, Serguei;
  • Abstract: To fully support decision making and to supplement what is observed in the field, we need to develop a glassy-winged sharpshooter (GWSS) performance database on the host plant species that are identified as truly critical to GWSS survival (particularly for immature GWSS). There are no quantitative data available on the relative suitability of single or multiple hosts most relevant in California to GWSS growth and development. This proposal will not only provide this baseline information, but also identify host plant limitations at different life stages and identify key nutrients responsible for this phenomenon.
