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.

Paratransgenesis as a potential tool for pest control: review of applied arthropod symbiosis

  • Author(s): Miller, TA;
  • Abstract: Research funds for addressing practical plant pest or disease problems are justified by the size of the threat and the financial burden it imposes. When new technology is developed for pest or disease control, regulatory costs to pay for risk assessments make sense when projected income from a new product can be charged to expected income from a future market. When a pest or disease problem affects a minor crop, the research to address regulatory issues does not have such a clear-cut funding origin. Ironically, a very selective biopesticide designed to address a local pest or disease problem is the ideal form of sustainable pest management, but has the smallest market of any pest control strategy and therefore the smallest amount of financial support. In this sphere of modest financial resources, regulatory needs can force research away from solving the problem at hand to address assessment issues that add considerable cost. When genetic modification is a part of the proposed new strategy, an added burden is placed on the developers. This burden can defy logic and can also come largely from peers, not the public.
