Single LBAM detected in Carpinteria; Marin twist-tie application to begin March 4
SACRAMENTO – A single light brown apple moth (LBAM), an invasive pest native to Australia, has been detected in the community of Carpinteria in Santa Barbara County.
The trap that caught the male moth was part of a statewide trapping array deployed to detect any new infested sites as early as possible. The detection triggered increased trapping in the immediate area to determine if additional moths are present.
A cooperative eradication program run jointly by CDFA and the U.S. Department of Agriculture (USDA) is already underway to suppress and eradicate infestations in nine counties along California’s Central Coast and Bay Area.
Cold Weather Delays Marin Twist-Tie Applications; Will Begin March 4
Cold weather over the past several weeks has led CDFA officials to adjust the start date for twist-tie application in the San Rafael area of Marin County to March 4. The pheromone-infused twist ties will hang on trees, plants and fences within approximately 200 meters of sites where moths have been trapped. The twist ties are designed to saturate the area with the moth pheromone, distracting the male moths and keeping them from finding female moths for mating. The twist-tie applications are timed to coincide with the emergence of adult moths in order to maximize the effectiveness of the pheromone. The application had been scheduled to start in February, but colder temperatures are delaying the development and emergence of the adult moths.
The pheromone used in the twist ties is highly specific to the targeted moth population. After approximately 90-120 days, depending on whether traps in the area detect any additional moths, the twist ties will either be removed or replaced.

Tuesday, February 19, 2008, 7:30 – 9:00 p.m.
Since its detection in February 2007, the Light Brown Apple Moth has been found throughout the central coast region in the counties of Monterey, Santa Cruz, Santa Clara, San Mateo, Contra Costa, Marin, San Francisco, Alameda and Solano. CDFA and the USDA continue work on treatment plans for communities within these counties. Small, isolated infestations detected last year in Los Angeles and Napa counties have already been eradicated. Twist ties were utilized in both counties.
