Most people have a hobby, be it ultra marathon running, travel, gardening, scrapbooking or making wine at home. And like most things in life, nearly every hobby has some level of risk involved—twisting an ankle running, slicing your finger scrapbooking or succumbing to illness while traveling. Home winemaking is facing a new risk, from the European Grapevine Moth (EGVM).

The trapping program has been underway for a few months now and it seemed like a good time to offer a little summary and look ahead. June 23rd, 2010 |

EGVM finds have been made recently in Fresno County, Mendocino County, Merced County and Solano County, in addition to the first finds in Napa and Sonoma Counties. Finding EGVM-infested sites is important, but equally important is knowing where it isn’t present. This information allows growers to assure customers that their products are EGVM-free.

| Tags: California, European Grapevine Moth, Invasive Pests | Category: Agriculture Quarantine | Leave a comment The European Grapevine Moth (lobesia botrana) has been in the news a lot lately. As I wrote in an earlier blog, EGVM was first found in Napa Valley—the first find in the United States—in fall 2009. It has now been found at more than 30 sites and growers in the Napa Valley are concerned about the impacts it may have to their crops. State Interior Quarantine boundaries were recently established by CDFA, covering 162 square miles of Napa, Sonoma and Solano Counties. An active trapping program is underway to help determine the extent of the infestation. March 30th, 2010 |
Author: Helene Wright, California State Plant Health Director, USDA-APHIS | Tags: European Grapevine Moth | Category: Pest Management | One comment Yet another new pest arrived in California in late 2009: the European Grapevine Moth, or Lobesia botrana. The first detection in the United States was in Napa County in September 2009. Since that first confirmed detection, European Grapevine Moth (EGVM) has been found on more than 30 properties in Napa County, mostly in the Oakville and Rutherford areas. EGVM is a big concern for vineyard owners and grape growers. The moth larvae pack a double whammy—not only do they impact the fruit, they make the plants more vulnerable to botrytis bunch rot, which can greatly impact grape production. Unlike other moths, EGVM eggs are laid on blossoms, leaves and tender twigs, and larvae feed in flowers and fruit, affecting more than the leaves or bark. The combination of damage from moth larvae and botrytis bunch rot can decimate a harvest. February 17th, 2010 |
