    • In California's San Joaquin Valley, scientists from the Agricultural Research Service (ARS) have a sharpshooter, and the pathogen it spreads, in their crosshairs. ARS Scientists in California are devising strategies to combat pests that cause over $100 million in damage to the grape industry.

    • USDA. ARS. Tellus.

    • Rodrigo Krugner, an entomologist with the Agricultural Research Service (ARS) in Parlier, California, has found an innovative way to control insect pests in California vineyards: tapping into the vibrational signals they use as mating calls.

      Krugner’s efforts have mainly focused on glassy-winged sharpshooters, which spread a bacterium that causes Pierce’s disease in vineyards and costs the California grape industry an estimated $104 million a year. Growers use chemical sprays to control the pests, but insecticides also kill beneficial insects, leave residues, and become less effective as the insects develop resistance.
