Inspectors in both Napa and Sonoma counties found glassy-winged sharpshooter (GWSS) egg masses on nursery shipments of plants in early March, leading to the destruction of the plants where those egg masses were found.
The first find was on March 7th by Napa County inspectors who discovered a single egg mass on some plants that were shipped from an Orange County nursery to a retail outlet in American Canyon, Calif.
Inspectors destroyed the affected variety of plants in which the egg mass had been found. No other GWSS life stages were found on the remaining plants.
Then on March 8th, Sonoma County inspectors found one GWSS egg mass on a plant that had also been shipped from the same supplier in Orange County.
