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.

  • Author(s): Daane, Kent; de Le?n, Jesse; Fournier, Valarie; Hagler, James; Costa, Heather; Prabhaker, Nilima;
  • Abstract: Using glassy-winged sharpshooter (GWSS) egg-specific monoclonal antibody (MAb) and GWSS-specific genetic markers that we previously developed and optimized, the guts of field-collected predators were screened for the presence of GWSS remains. We have examined the guts of over 700 generalist predators and our analyses revealed that frequent predators of the GWSS include spiders, assassin bugs, lacewings and praying mantis.
