Fresno County Agricultural Commissioner Carol Hafner held a news conference yesterday to outline efforts to combat European grapevine moth after three were detected last week in Fresno County. The ag commissioner's office has been monitoring thousands of traps in the county as part of a statewide program to detect the invasive pest.
On April 28, the officials confirmed that two European grapevine moths were found in separate traps about a half mile apart in vineyards southeast of the city of Fresno. On May 1, one moth was found in a trap in the Kingsburg area.
Grape production is the No. 1 ag industry in Fresno County, with an annual value of more than $700...
As authorities collaborate on a battle plan to combat European grapevine moth, the pest has been detected in a new area.
The Santa Rosa Press Democrat reported last week that 13 moths were found in a North Ukiah chardonnay vineyard, the first evidence the pest has reached Mendocino County. The discovery of the moths means that a quarantine with a three-mile radius around the vineyard will be established.
Mendocino County Ag Commissioner Tony Linegar believes the moth was transported on winegrapes from Napa County, where infestations are high, the story said. European grapevine moth, a native of the Mediterranean region, was...
A recently certified report on light brown apple moth asserts that the pest, native to Australia, cannot be eradicated from California.
"Given the increases in LBAM population densities and the extent of contiguous spread of LBAM observed over the past 2 years, coupled with a lack of area-wide management tools, eradication is no longer feasible in California," the USDA report says.
The "area-wide management tools" referred to in the report includes aerial pheromone spraying, which drew the ire of many environmentalists. Instead, control will be attempted with twist-ties that release pheromones and...
A group of UC scientists traveled to Chile recently to see firsthand vineyard damage caused by the European grapevine moth, according to an article in the Fresno Bee. The moth has been detected in California's Napa County, and is being actively tracked in the valley to determine whether the infestation has spread.
European grapevine moth was discovered three years ago in Chile. Because the pest develops from larvae to moth at a crucial time in the grape's growth cycle, its effects can be devastating.
"They have lost whole vineyards in Chile; not one grape was picked," UC entomologist
A fruit fly that made its first California appearance four years ago in Watsonville - spotted wing drosophila - can be managed with three basic common-sense techniques.
"It's going to come down to trapping, monitoring and good sanitation," Mark Bolda, University of California Cooperative Extension farm adviser in Santa Cruz, Monterey and San Benito counties, told a group of growers in January, according to an article in the Santa Cruz Sentinel.
