Light Brown Apple Moth in San Joaquin County
Department of Food and Agriculture (CDFA) recently confirmed that 2 moths
trapped in the Guard Road area Southwest of Thornton were Light Brown Apple
Moth (LBAM). As a result, a
Federal/State plant quarantine was established in this area. The purpose of the
quarantine is to prevent further spread of Light Brown Apple Moth by
controlling the movement of plant material that could carry LBAM outside of the
quarantined area. In general the quarantine boundary encompasses a 1 ½ mile
area surrounding the moth finds.
We are presently contacting the growers with
fields within the quarantine boundaries so that we can obtain the necessary information
for quarantine compliance agreements that will ensure the timely flow of
commodities from their fields and facilities.
Each grower in the quarantine area must have a signed compliance
agreement before moving harvested commodities from their fields.
In March 2007, USDA confirmed the presence of Light Brown Apple Moth (LBAM), Epiphyas Postvittana in Alameda County. By July of that same year it had been found in 8 San Francisco Bay area Counties as well as the counties of Santa Cruz, Monterey and Los Angeles. Since then, despite numerous methods and attempts at eradication, Light Brown Apple Moth has continued its spread across the cooler regions of California, including moving eastward up the Delta and into San Joaquin and Sacramento Counties.

A single Light Brown Apple Moth was trapped in Manteca in June 2009. A second moth in July triggered San Joaquin County’s first quarantine. This quarantine area was declared eradicated, only to have another series of finds in Tracy area. This began the battle San Joaquin County has been fighting to prevent the spread of LBAM into the county.
