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.

  • Abstract: The purpose of the work planned in this project is to determine whether the Minnesota strain of the mymarid, Anagrus epos Girault (A. epos), we have in culture on glassy-winged sharpshooter (GWSS) is the same species as A. epos strains previously released in California, how it compares with other A. epos strains, and whether there are other strains of A. epos that should be imported for biological control of GWSS. Without understanding what species we have and how the Minnesota strain is related to similar strains, it is difficult to know how to proceed in selecting strains of this species to culture for mass-rearing and release in California for GWSS control. Concurrently, we will evaluate field releases and establishment of the Minnesota A. epos strain at six release sites in southern California.
