The blotchy-brown European grapevine moth, which showed up in Napa County in the fall of 2009, is described as a “significant invasive pest” by the U.S. Department of Agriculture. Larvae emerge in three generations, beginning in late May and continuing through September. These pests damage grapevines by forming webs over and feeding on flower clusters, unripe grapes and grape bunches, emptying the grapes and leaving skin and seeds. Control often is targeted at the second generation to avoid re-infestation from untreated vineyards. Reduced-risk pesticides, including growth regulators, spinosyns and Bacillus thuringiensis, are registered for this use in California. Other control measures include removal of contaminated grapes and vines, and breeding-cycle disruption. Quarantines have been used to slow infestations in some areas of California. Because this is a recently introduced pest, research to find the best control is ongoing.
