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.

SEARCHING FOR AND COLLECTING EGG PARASITOIDS OF THE GLASSY-WINGED SHARPSHOOTER IN THE CENTRAL AND EASTERN USA

  • Author(s): Hoddle, Mark; Triapitsyn, Serguei; Morgan, David; Rakitov, Roman;
  • Abstract: Presence of the proconiine sharpshooters Homalodisca coagulata (Say) (GWSS - the Glassy-winged Sharpshooter) and its close relative Oncometopia orbona (Fabricius) (the Broad-headed Sharpshooter) in their native range in central and eastern United States justifies conducting a survey of their principal natural enemies, egg parasitoids in the families Mymaridae and Trichogrammatidae. No such surveys have ever been conducted North of Georgia, Alabama, Mississippi, Louisiana, and Texas. Prior research showed presence of the mymarid Gonatocerus fasciatus Girault there (Triapitsyn et al. 2003). In addition, a number of trichogrammatid genera and species have been recognized in central and eastern USA.
