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.

ELEVATIONS EFFECT ON SURVIVAL OF GLASSY-WINGED SHARPSHOOTER IN KERN COUNTY

  • Author(s): Luvisi, Don; Bedard, Franklin;
  • Abstract: The ability of glassy-winged sharpshooter (GWSS) to successfully over-winter within various crops in Kern County, California is of paramount interest to those seeking to control this pest. The eastern edge of the San Joaquin Valley is heavily planted with citrus, a preferred host plant for feeding and oviposition. This belt of host plants located within a suspected over-wintering survival zone could create a highway for rapid northern dispersal of GWSS. These extensive citrus plantings are located at various elevations along a thermal belt that experiences warmer winter temperatures than the valley floor. In addition, the valley floor is subjected to fog and continuous temperatures in the range of 3-5 C.
