Light Brown Apple Moth Eradication Information

The Light Brown Apple Moth (LBAM), a serious new insect pest, has been detected on Treasure Island in the city of San Francisco (MAP). This moth feeds on more than 250 varieties of plants and is a threat to California’s natural environment as well as our agricultural economy. Emergency eradication and quarantine action is needed to protect California from the negative environmental and economic impacts the establishment of this pest would cause.

SENSITIVE AREAS

In consultation with the appropriate federal and state agencies, all designated environmentally sensitive locations within and/or adjacent to the eradication area have been identified and will be properly protected. Environmental monitoring will be conducted within the treatment areas to insure that the applications are properly applied.

ERADICATION PLAN

The proposed eradication area encompasses those portions of San Francisco County which fall within approximately 0.33 square miles in the boundaries of Treasure Island (MAP). If additional LBAM are detected outside of the eradication zone, the area will expand as necessary.

The eradication plan consists of the following elements:

  1. Trapping - Jackson traps baited with the LBAM pheromone lure will be placed in the treatment area at the density of 100 traps per square mile where LBAM has been detected and 25 traps per square mile in the square miles adjacent to the find sites. Additional traps may be added to further delimit the infestation and to determine the efficacy of treatments. All monitoring traps will be serviced on a regular schedule for a period of time equal to three generations beyond the date of the last LBAM detection.


  2. Treatment – Ground applications with pheromone-infused “twist ties” placed on trees, shrubs and objects such as fence posts on designated residential properties within a 200 meter radius of each moth capture. The twist tie dispensers contain an odorless insect pheromone (sexual attractant) that confuses male moths, impairing their ability to find mates. Once the breeding cycle of the moth is broken, the light brown apple moth population is reduced and ultimately eradicated from the area. Residents in the affected area will be notified in writing at least 24 hours prior the deployment of the twist ties.
  3. Post-Treatment Monitoring – Light Brown Apple Moth traps will be inspected for one life cycle following the last deployment of the twist ties.
