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.

A MONOCLONAL ANTIBODY SPECIFIC TO GLASSY-WINGED SHARPSHOOTER EGG PROTEIN: A TOOL FOR PREDATOR GUT ANALYSIS

  • Abstract: Egg-specific monoclonal antibodies (MAbs) have been developed to the glassy-winged sharpshooter (GWSS). Younger GWSS eggs yield stronger ELISA reactions than older eggs. The indirect ELISA format was not effective for detecting GWSS egg antigen in whole body or gut dissected earwig specimens. Further ELISA optimization tests are underway to increase the efficiency of the ELISA procedure. A survey of the predator complex inhabiting citrus in Riverside, CA indicates that the earwig, Forficula auricularia is the most common predator.
