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.

EXPLORATION FOR BIOLOGICAL CONTROL AGENTS IN THE NATIVE RANGE OF THE GLASSY-WINGED SHARPSHOOTER

  • Author(s): Goolsby, John; S?tamou, Mamoudou;
  • Abstract: A new initiative to study the ecology of GWSS in its native non-crop habitat is underway. Several sites in southeastern Texas have been selected each with stands of native Vitis spp. Monthly trapping will be used to determine the phenology of GWSS and other proconine sharpshooters. Several methods including hand collection, egg and nymphal sentinels, sweeping, and baits will be used to assess the diversity of natural enemies at each location. Since previous biological control efforts have focused on egg parasitoids of GWSS, these exploration efforts will be emphasize discovery of nymphal parasitoids.
