Pests in Southern California
The Department operates Entomology and Plant Pathology Laboratories, which seek to protect consumers by identifying exotic insects (and other invertebrates), invasive weeds and plant pathogens entering Los Angeles County through truck, ship, airfreight, and parcel delivery operations. The laboratories provide rapid and accurate identifications to support the Pest Detection and Pest Exclusion programs and offer identification and information services for Los Angeles County residents, schools, governmental agencies, growers, nursery and pest control operators. Overall, the laboratories process over 8,000 pest specimens submitted annually.

Recognize Forest Pests
The Exotic Forest Insect Guidebook, originally published in 2004 by the Canadian Food Inspection Agency, includes descriptions of insects, the damage they cause, the host trees they attack, and their geographic distribution. Most of the species identified in this guide could pose a serious risk to northern forests if introduced. Some have already been established in North America.

EAB continues to spread
On October 8, the USDA Animal and Plant Health Inspection Service (APHIS) confirmed the identification of EAB in Fayette and Morgan Counties in West Virginia. Recently, the presence of EAB was also confirmed in Roane County. Previously, APHIS had established quarantine areas only Fayette and Morgan Counties due to the establishment and enforcement of equivalent State quarantines. West Virginia has now rescinded their EAB quarantines. For this reason, APHIS is establishing quarantine for the entire State of West Virginia in order to prevent the spread of EAB to other states.

Windsor, Canada. By 2002, the beetle – by that time recognized as the emerald ash borer (EAB) – was well established in Michigan and Ontario, Canada, and estimates were that it had already killed or infested at least 5 million ash trees in open settings, woodlots and forest stands. In response, quarantines were enacted in the United States and Canada to stop the human-assisted spread of the infestation.
