We haven’t heard much about the European Grape Moth lately. The California Department of Food and Agriculture put out traps over an extensive area of Nevada County in response to the grapevine moths that were found in vineyards and one back yard grape vine in the County last may. They put out 1,850 traps and 4 moths were found. Nevada County Agriculture Commissioner Jeff Pylman says they haven’t found any additional moths in traps since May. He says Nevada County may be able to get out from under the quarantine by the end of next year.
“That’s a good possibility. If we don’t find anymore in traps, we can possibly get out from underneath the quarantine. The quarantine is not that bad. We’re not limiting growers from transporting their grapes to the wineries, we just have to be sure that they’re using the best management practices so that the moths or the eggs or the larve don’t go with the shipment.”
The European Grapevine Moth during its third generation can lay eggs on the skin of grapes and when those eggs hatch they start eating grapes from the inside out, spoiling them for table grapes or wine grape production.
The quarantine area currently in effect includes Nevada City, Grass Valley, Rough and Ready, Penn Valley, and Lake Wildwood.
