USDA. Animal and Plant Health Inspection Service.

Effective immediately, the Animal and Plant Health Inspection Service (APHIS), in cooperation with the Alabama Department of Agriculture and Industries (ADAI), is establishing a quarantine for Elsinoë australis, the fungal causal agent of sweet orange scab (SOS), in all of Baldwin and Mobile Counties in Alabama to prevent the spread of the disease.

Elsinoë australis was first detected in the United States in July 2010; and with these recent detections, is known to occur in Arizona, Florida, Louisiana, Mississippi, Texas, and portions of California and Alabama. This Federal Order supersedes Federal Order, DA-2016-55, but does not change the requirements for interstate movement of regulated articles from these quarantine areas. A description of all current SOS quarantine areas, Federal Orders, and other supporting regulatory documents may be found on the APHIS website.

Effective immediately, the Animal and Plant Health Inspection Service (APHIS) is expanding the Phytophthora ramorum (P. ramorum) quarantine area in Del Norte County, California. APHIS is taking this action in response to the confirmation of P. ramorum in the county on September 19, 2020. The California Department of Food and Agriculture has established an intrastate quarantine for the areas in Del Norte County that mirrors the federal regulatory requirements as specified in 7 CFR 301.92.

P. ramorum is the pathogen that causes sudden oak death, ramorum leaf blight, or ramorum dieback. Sudden oak death was first reported in 1995 on tan oak in Mill Valley, Marin County, California. Through ongoing surveys, APHIS continues to define the extent of the pathogen's distribution in the United States and uses quarantine areas and public outreach to limit its artificial spread beyond infected areas. Details on APHIS-designated P. ramorum quarantine and regulated areas and the conditions to move regulated articles are in 7 CFR 301.92 and at the APHIS website.

Effective September 30, 2021, the Animal and Plant Health Inspection Service (APHIS) and the California Department of Food and Agriculture (CDFA) established an Oriental fruit fly (Bactrocera dorsalis or OFF) quarantine in the San Jose area of Santa Clara County, California. This action is in response to the confirmed detections of six adult male OFF from the San Jose area by CDFA between September 13 and September 24, all from traps in various types of fruit trees in residential areas. By October 4, CDFA confirmed the seventh male OFF in the vicinity of the earlier finds, which expanded the quarantine further. The establishment of this quarantine area is reflected on the APHIS website, which contains a description of all current Federal fruit fly quarantine areas.

Effective immediately, the USDA's Animal and Plant Health Inspection Service (APHIS), in cooperation with the Alabama Department of Agriculture and Industries (ADAI), is establishing quarantines for Huanglongbing (HLB; citrus greening), caused by Candidatus Liberibacter asiaticus, in all of Baldwin and Mobile Counties in Alabama. APHIS is taking this action because of HLB detections in plant tissue samples collected in multiple locations in Alabama.

APHIS is applying safeguarding measures on the interstate movement of regulated articles from the quarantined counties in Alabama. These measures parallel the intrastate quarantine that ADAI established on June 2, 2020. This action is necessary to prevent the spread of HLB to non-infested areas of the United States.

Effective November 16, 2021, the Animal and Plant Health Inspection Service (APHIS) and the California Department of Food and Agriculture (CDFA) established a Mediterranean fruit fly (Medfly) quarantine area in San Bernardino and Los Angeles Counties, California. APHIS is applying safeguarding measures and restrictions on the interstate movement or entry into foreign trade of regulated articles from this area. This action is in response to the CDFA’s confirmation of a mature, unmated female Medfly on October 25, and a subsequently confirmed male Medfly on November 9 from Jackson traps placed in backyard citrus trees in residential areas of Upland, California. There are 15.75 acres of commercial agricultural production in the quarantine area. Currently, the quarantine area encompasses 95 square miles.

Effective May 11, 2021, the Animal and Plant Health Inspection Service (APHIS) and the New York State Department of Agriculture and Markets (NYS AGM) expanded the European cherry fruit fly (ECFF) quarantine to include all of Monroe County and Wayne County and a small portion of northwestern Ontario County, New York. With this expansion, the ECFF quarantine now includes all of Erie, Monroe, Niagara, Orleans, and Wayne Counties. This action is necessary to prevent the spread of ECFF to non-infested areas of the United States, while maintaining commercial cherry production and marketing within the state. The APHIS website reflects the expansion of this quarantine and contains a description of all the current federal fruit fly quarantine areas.

Effective December 17, 2021, the Animal and Plant Health Inspection Service (APHIS) is removing the light brown apple moth (LBAM), Epiphyas postvittana, quarantine in California and Hawaii. APHIS is reclassifying LBAM as a non-quarantine pest, removing all areas under quarantine, and removing movement restrictions on LBAM host material.

When APHIS first confirmed detections of LBAM in the United States in 2007, the best science available indicated that this moth would be a pest of economic significance. In response, APHIS and the California Department of Food and Agriculture (CDFA) developed an eradication program. Over time, however, it became clear that the moth’s impact was not as significant as expected.

Effective immediately, the Animal and Plant Health Inspection Service (APHIS) is removing 45,562.067 acres from the golden nematode (GN) regulated area in Suffolk County, New York and refining the global positioning system (GPS) points for the descriptions of the regulated area in the town of Oyster Bay in Nassau County, New York. APHIS is removing these areas based on survey results and other criteria in the "Canada and United States Guidelines on Surveillance and Phytosanitary Actions for the Potato Cyst Nematodes, Globodera rostochiensis and Globodera pallida”.

Since 2010, APHIS, working closely with the New York State Department of Agriculture and Markets (NYS AGM), has removed 1,186,693.79 acres from the GN-regulated area in New York. APHIS and NYS AGM have an active control and mitigation program in place to prevent GN from spreading from the remaining 101,955.27 acres, including 5,945 GN-infested acres in eight New York counties. The specific GN-regulated areas are on the APHIS website.

A state exterior quarantine has been declared to prohibit the introduction of the spotted lanternfly (SLF), Lycorma delicatula, into California. Spotted lanternfly was first detected in North American in 2014 in Pennsylvania and has now spread to nine states. The quarantine prohibits the entry into California of SLF, its host plants, and a variety of articles, including conveyances, originating from any area where an SLF infestation exists.

If you believe you have seen the spotted lanternfly, please contact CDFA's Invasive Species Hotline at 1-800-491-1899, via Report a Pest, or by contacting your local County Agricultural Commissioner.
