Humans adores trees. But humans also migrate and trade, habits that led to the accidental introduction of insects and diseases that harm trees and alter the landscape. Examples are easy to find and may be outside your front door: American elms that once dotted streets across America succumbed to Dutch elm disease. Now all colors of ash species – black, green, white, pumpkin, and blue – are threatened by emerald ash borer. The already uncommon butternut tree, also known as white walnut, faces the possibility of extinction from a mysterious attacker. Many invasive insects and fungi come from regions where native trees have evolved to resist their attacks. When these species enter the United States, they find trees that lack this resistance. There's no immediate end to this dismal pipeline, but there is hope on the horizon.

Agricultural Research Service (ARS) scientists are tracking a honey bee killer, and their investigations have taken them from hives in Tucson, Arizona, to Bismarck, North Dakota. Led by ARS entomologist Gloria DeGrandi-Hoffman, the team is staking out hive entrances and monitoring the comings and goings of foraging honey bees, which may be the killer's unwitting accomplices. None of the busy little winged bearers of pollen and nectar will get by without inspection: The prime suspect—an eight-legged, pinhead-sized parasite called the Varroa mite—seems to be sneaking into the hives on the bees' bodies. The Varroa mite, Varroa destructor, is considered public enemy number one to honey bees nationwide. The parasite feeds on the blood of adult bees and their brood, weakening them and endangering the entire hive when infestations become severe. But the mite also poses an indirect threat to more than 90 flowering crops that depend on bee pollination, including almonds, apples, blueberries, cherries, and cantaloupes.

USDA's Plant Protection and Quarantine (PPQ) continuously takes steps to enhance our ability to exclude, control, and eradicate pests and increase the safety of agricultural trade. Across the country, PPQ worked with the States and other partners to detect, contain, and when possible, eradicate invading pests. On the world stage, PPQ worked closely with our international trading partners to develop and promote science-based standards, helping to create a safe, fair, and predictable agricultural trade system that minimizes the spread of invasive plant pests and diseases. Learn about the many successes and accomplishments captured in the 2018 report (APHIS 81-05-021) and how PPQ is working every day to keep U.S. agriculture healthy and profitable.

The United States Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) has analyzed the potential environmental effects of establishing an integrated management strategy to control cogongrass in Alabama, Georgia, Mississippi, and South Carolina. The draft environmental assessment is now available for comment. Cogongrass is an invasive exotic grass found on public and private property, along roadways, in forests, and on farmland. This federally regulated noxious weed grows rapidly, reducing forest productivity, harming wildlife habitat and ecosystems, and encroaching on pastures and hayfields. Because of cogongrass' impact on agriculture and forest industries, Congress has given APHIS funding to partner with Alabama, Georgia, Mississippi, and South Carolina to control the spread of this weed. APHIS is proposing is an integrated management strategy that uses preventive, cultural, mechanical, biological, and chemical methods to control cogongrass in key areas of its distribution. APHIS invites the public to review and comment on this environmental assessment by April 1, 2020.

The United States Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) has analyzed the potential environmental impacts of releasing a parasitoid wasp to biologically control the Russian wheat aphid. The Russian wheat aphid is a wingless, pale yellow-green or gray-green insect lightly dusted with white wax powder that feeds and develops on grass and cereal species. The biological control agent is a small, stingless wasp called Aphelinus hordei that can be used to reduce the severity of damage caused by Russian wheat aphids. Based on our assessment and other relevant data, releasing this biological control agent will not have a significant impact on the quality of the human environment. APHIS invites the public to review and comment on the environmental assessment until June 4, 2020, 30 days after publication in the Federal Register on May 5, 2020.

The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) is launching a new “Pests and Diseases” webpage. The new page lists all pest and disease programs managed by APHIS as part of its mission to protect American agriculture and natural resources.

 

On the new page, users can search by type (plant, animal), keyword (avian, fruit fly, cotton), or by the specific pest or disease (coconut rhinoceros beetle, brucellosis). You can also scroll through the page, which lists the pests and diseases alphabetically and includes a corresponding image.

 

APHIS created the webpage to make it easier for its customers to find critical information on pests and diseases of concern. With this tool, members of the public will have the information they need to report pests and diseases and together we can protect America’s agriculture and natural resources.

The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) is proposing to lift the domestic quarantine for pine shoot beetle. Despite efforts to control pine shoot beetle since it was first detected in 1992, this pest, which only infests stressed and dying pine trees, is now found in 20 states in the northeast and north central parts of the country. Given the limited impact of interstate movement restrictions on the beetle’s spread and the minimal damage this pest has caused to native pines, plantations, and nursery trade, we are proposing to remove the pine shoot beetle domestic quarantine. This action would allow the states to determine the best approach for managing the pest within their boundaries, relieve impacted businesses and individuals from having to comply with costly and burdensome restrictions, and allow APHIS to focus limited federal resources on higher risk pests. APHIS will carefully consider all comments received.  Beginning Monday, members of the public will be able to submit comments for 60 days, or until November 22, 2019 at: https://www.regulations.gov/docket?D=APHIS-2016-0065

The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) is seeking feedback on its proposed list of pests and diseases of concern that are likely to pose a high risk to U.S. agricultural and natural resources.

Section 12203 of the 2018 Farm Bill requires pest- and disease-planning activities that mirror the extensive planning efforts APHIS already performs. Specifically, it requires APHIS to develop a uniform list of pests and diseases that represent the gravest threat to the United States and to develop comprehensive response plans to ensure Federal and State governments are prepared to respond to them.

See Animal and Plant Diseases and Pests of Concern for more information. The agency will review comments from the public about the list, including suggestions of pests or diseases that should be added or removed. In providing comments, individuals should keep in mind that the Farm Bill definition of a pest or disease of concern limits this list to those that are “likely to pose a significant risk to the food and agricultural critical infrastructure sector” and is not meant to be an exhaustive list of all possible pests or diseases. Comments may be submitted to APHISPestDiseaseList@usda.gov.

Research by scientists at the Agricultural Research Service (ARS) and the University of Maryland released today sheds new light -- and reverses decades of scientific dogma -- regarding a honey bee pest (Varroa destructor) that is considered the greatest single driver of the global honey bee colony losses. Managed honey bee colonies add at least $15 billion to the value of U.S. agriculture each year through increased yields and superior quality harvests. The microscopy images are part of a major study showing that the Varroa mite (Varroa destructor) feeds on the honey bee’s fat body tissue (an organ similar to the human liver) rather than on its “blood,” (or hemolymph). This discovery holds broad implications for controlling the pest in honey bee colonies.
