White-nose syndrome has been spreading through U.S. bat populations since 2006 and has caused mass die-offs in various regions of the country. The syndrome is caused by Pd (Pseudogymnoascus destructans), a fungus that invades the skin of bats while they hibernate. USDA Forest Service wildlife biologists Roger Perry and Phillip Jordan conducted a study to calculate the survival rates of tricolored bats (Perimyotis subflavus) in the Ouachita Mountains of west-central Arkansas. The research helps satisfy the need for robust estimates of population data amid the WNS outbreak. The scientists chose to study the tricolored bat because it is common across North America and has suffered substantial declines due to WNS. The research highlights the importance of maintaining and protecting small hibernation sites as they may be critical to the conservation of the tricolored bat species.

On Tuesday, June 5, 2018, the United States Department of Agriculture (USDA) National Veterinary Services Laboratory (NVSL) confirmed the presence of the Longhorned tick (Haemaphysalis longicornis) in Arkansas. The Longhorned tick is an exotic East Asian tick associated with bacterial and viral tickborne diseases of animals and humans in other parts of the world. This tick is considered by USDA to be a serious threat to livestock because heavy tick infestations may cause stunted growth, decreased production and animal deaths. Like deer-ticks, the nymphs of the Longhorned tick are very small (resembling tiny spiders) and can easily go unnoticed on animals and people. This tick is known to infest a wide range of species and has the potential to infect multiple North American wildlife species, humans, dogs, cats, and livestock.

The U.S. Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) is announcing its plans for combatting the Asian longhorned beetle (ALB) in New York, Massachusetts, and Ohio in 2020. "Just last year we declared eradication of ALB from Brooklyn and Queens in New York City, ending the city's 23-year-long battle with the beetle," said Osama El-Lissy, APHIS' Plant Protection and Quarantine Deputy Administrator. "This year, we've mapped out a sound strategy that will further our efforts to eliminate this pest from the remaining areas of this country where it still has a foothold."

Every year, APHIS evaluates and determines the most effective options to achieve ALB eradication. In 2020, the ALB program will focus on inspecting trees in quarantined areas in New York, Massachusetts, and Ohio, and removing infested trees at no cost to property owners. The program will not apply insecticide treatments this year. In addition, program officials will monitor for the beetle’s presence inside and around each area, respond to service calls, conduct training sessions for compliance agreement holders, and perform outreach.

The United States Department of Agriculture's (USDA) Animal and Plant Health Inspection Service (APHIS) is announcing that effective today, we are transitioning our virulent Newcastle disease (vND) efforts in southern California from a response focus to implementing a prevention plan aimed at keeping vND from recurring in the region. Even with extensive testing taking place, APHIS has not confirmed any new vND cases since February 1, 2020. As a result, the California Department of Food and Agriculture (CDFA) is removing its vND quarantine.

USDA's Animal and Plant Health Inspection Service (APHIS) confirmed the presence of virulent Newcastle disease in a commercial chicken flock in Riverside County, California. This finding is part of an outbreak in southern California that began in May 2018 in backyard exhibition birds. This is the first case in commercial poultry since 2003.

Virulent Newcastle disease is not a food safety concern.  No human cases of Newcastle disease have ever occurred from eating poultry products.

The United States Department of Agriculture's (USDA) Animal and Plant Health Inspection Service (APHIS) confirmed the presence of virulent Newcastle disease in a small flock of backyard exhibition chickens in Los Angeles County, California. It is important to note that the presence of the disease is not a food safety concern. This is the first case of virulent Newcastle disease, previously referred to as exotic Newcastle disease, in the U.S. since 2003.

On October 10, 2019, the U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) in coordination with the New York State Department of Agriculture and Markets, New York State Department of Environmental Conservation, and New York City Department of Parks and Recreation announced that they have eliminated the Asian longhorned beetle (ALB) from the New York City boroughs of Brooklyn and Queens. "I am proud to say that we have eradicated Asian longhorned beetle from Brooklyn and Queens," said Greg Ibach, USDA's Under Secretary for Marketing and Regulatory Programs. "This officially marks the end of our 23-year long battle with this pest in New York City."

The United States Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) has established a quarantine for European cherry fruit fly (ECFF) in New York. A portion of Niagara County was quarantined for the invasive fruit fly following the detection of 51 flies in 2017. As of January 2020, the quarantined area has been expanded to include all of Niagara, Erie, and Orleans Counties. APHIS and the New York State Department of Agriculture and Markets (NYSDAM) are working collaboratively on this detection. See also: Fruit Flies Quarantine for additional information.

Secretary Perdue is making available an additional $45 million to the Animal and Plant Health Inspection Service (APHIS) and its partners to address the ongoing virulent Newcastle disease (vND) outbreak in southern California. This funding will allow APHIS and the California Department of Food and Agriculture (CDFA) to strengthen their joint efforts to stop the spread of this disease and prevent it from affecting additional commercial flocks. vND has been confirmed in more than 435 backyard flocks since May 2018. It was also confirmed in four commercial flocks in December 2018 and January 2019.

An invasive species is on the move and may be headed for Montana. Palmer amaranth, a giant pigweed, is known to have spread to at least 28 states, including Minnesota and South Dakota, but has not yet been reported in Montana. To prevent its spread into Montana, landowners are encouraged to check their fields to ensure the invasive weed is not present. It was a known contaminant in Conservation Reserve Program (CRP) seed mixes but pollinator, wildlife habitat and cover crop plantings may also been contaminated. Producers with recent conservation plantings should check their fields to ensure this invasive weed is not present.
