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.

U.S. Customs and Border Protection (CBP) agriculture specialists have already intercepted a dozen significant and potentially destructive pests this year at various ports of entry in Florida as part of the agency's all-encompassing efforts to safeguard American agriculture.

Unknown pests pose a significant risk in agriculture due to a lack of knowledge in controlling the pests and the extent of damage they can cause to crops. U.S. Department of Agriculture (USDA) entomologists recently classified eight pests discovered by CBP agriculture specialists in Florida as first-in-the-nation interceptions and another pest as a new species.

Early in October 2016, the U.S. Department of Agriculture (USDA) was faced once again with New World screwworm, which had been eradicated from the United States more than three decades ago. Infestation of this flesh-eating parasite was confirmed in deer from the National Key Deer Refuge in the Florida Keys.

 

USDA’s Animal and Plant Health Inspection Service (APHIS) immediately began releasing sterile male flies in Florida’s affected areas as part of an aggressive eradication campaign. By March 2017, the screwworm had been successfully eradicated from Florida.

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.

The U.S. Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) is working with the Texas Department of Agriculture (TDA) to combat the Mexican fruit fly (Anastrepha ludens) in Cameron and Willacy Counties in Texas. Following the detection of this pest in Cameron and Willacy Counties in January 2020, APHIS put quarantines in place to contain this fruit fly and is conducting surveys to find and treat infestations. Mexican fruit fly is one of the world's most destructive invasive pests, attacking more than 40 different kinds of fruits and vegetables. This invasive fruit fly does not harm humans or animals but it poses a serious threat to the Texas citrus industry.

APHIS needs the public's help to limit this invasive fruit fly's spread. We are asking residents living or working within Mexican fruit fly quarantine areas to cooperate with survey teams and give them access to your property. Surveyors will have official credentials identifying them as U.S. Department of Agriculture or TDA employees. With the residents' permission, they will inspect fruit trees on residential properties in quarantine zones and hang traps. If APHIS or TDA detect Mexican fruit flies, they will work with residents and business owners to eradicate the pest from infested properties.

If you live in the Lower Rio Grande Valley and think you might have Mexican fruit flies on your property, please call APHIS at 956-421-4041. With your help, we can protect local agriculture and stop the spread of this destructive pest.

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.

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."

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.
