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.

SAMPLING, SEASONAL ABUNDANCE, AND COMPARATIVE DISPERSAL OF GLASSY-WINGED SHARPSHOOTERS IN CITRUS AND GRAPES: DISPERSAL PROGRESS REPORT

  • Author(s): Hagler, Jacquelyn; Simmons, Gregory;
  • Abstract: Insect dispersal can be influenced by numerous factors, such as increasing population densities, reproductive status, biased sex ratios, host breadth, declining host quality and changing environmental conditions (Denno 1979, 1985; Taylor 1985, Denno et al. 1991, Blackmer and Phelan 1991, Blackmer and Byrne 1993a,b, 1999; Blackmer and Cross 2001). A better understanding of how these various factors influence the movement of the glassy-winged sharpshooter will be crucial in the management of this pest and the spread of Pierces disease (PD).
