    • Invasive Carp Regional Coordinating Committee.

    • The Invasive Carp Regional Coordinating Committee (ICRCC) announced the release of its 2022 Invasive Carp Action Plan, a comprehensive portfolio of 60 projects focused on Great Lakes protection. The Action Plan serves as a foundation for the work of the ICRCC partnership — a collaboration of 28 U.S. and Canadian federal, state, provincial, tribal, regional, and local agencies.

  • Avian Influenza Research Sheds Light on Possible Routes of Introduction to North America

    • Apr 22, 2022
    • DOI. USGS. National Wildlife Health Center.

    • Understanding how wild birds facilitate the maintenance, reassortment, and dispersal of influenza A viruses (IAV) is key to forecasting global disease spread. The current highly pathogenic avian influenza outbreak in North America highlights the question of how viruses are transported between continents. Recent NWHC research sheds light on this question and the potential role Iceland may play.

  • Invasive Jumping Worms Can Change Their World

    • Apr 22, 2022
    • USDA. Forest Service.

    • The invasive Asian jumping worm (Amynthas agrestis) has many common names: Alabama jumpers, Jersey wrigglers, wood eel, crazy worms, snake worms, and crazy snake worms. “Invasive Asian jumping worms got their name because of the way they thrash around,” said Mac Callaham, a Forest Service researcher who specializes in soils. “They can flip themselves a foot off the ground.”

      Like other earthworms, Asian jumping worms eat tiny pieces of fallen leaves. But there’s a problem. Those fallen leaves make up the top layer of forest soil. The litter layer, as it’s called, is home to a vast number of tiny animals. Many plants can’t grow or spread without the layer of leaf litter. “Soil is the foundation of life – and Asian jumping worms change it,” says Callaham. “In fact, earthworms can have such huge impacts that they’re able to actually reengineer the ecosystems around them.”

    • USDA. Animal and Plant Health Inspection Service.

    • In 2022, the U.S. Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) celebrates 50 years of serving the public. While a lot has changed in 50 years, our key mission remains protecting American agriculture and natural resources. To celebrate, we are looking back through our history and posting decade-by-decade timelines.

  • History Highlight: APHIS Launches Large-Scale Boll Weevil Eradication Program

    • Apr 18, 2022
    • USDA. Animal and Plant Health Inspection Service.

    • Few agricultural commodities have defined America the way cotton has. And few agricultural pests have been as destructive and downright insidious as the boll weevil, a small insect that lives and feeds on cotton bolls and flowers and reproduces very quickly.

      The national cooperative boll weevil eradication program is widely considered to be one of the most consequential agricultural programs in U.S. history. To date, APHIS, State agencies, and the cotton industry have eradicated this pest from more than 98 percent of U.S. cotton acreage.

  • Pennsylvania Fish and Boat Commission Urges Anglers And Boaters To Help Prevent Spread Of Invasive New Zealand Mudsnails

    • Apr 20, 2022
    • Pennsylvania Fish and Boat Commission.

    • Recent surveys by the PFBC and partner organizations have detected New Zealand mudsnails, roughly the size of a match head, in several popular cold-water trout fisheries in central and eastern Pennsylvania. In some infested waters, New Zealand Mudsnails have the potential to reach densities of hundreds or even thousands of snails per square foot. These snails are not harmful to humans but can compete with and negatively impact native freshwater invertebrate species, such as other snails and aquatic insects.

      Until recently, New Zealand Mudsnails were known to occur only in Lake Erie, Erie County; Spring Creek and Bald Eagle Creek, Centre County; and the Little Lehigh Creek in Lehigh and Berks counties. Surveys during 2020 revealed populations of snails in Trindle Spring Run, Cumberland County; Codorus Creek, York County; and Valley Creek, Chester County; prompting expanded surveys. Members of the public who observe suspected New Zealand Mudsnails or other aquatic invasive species may report their sightings to the Commission.

  • Sawfly GenUS is Now Complete

    • Apr 5, 2022
    • USDA. APHIS. PPQ. CPHST. Identification Technology Program.

    • ITP is pleased to announce that Sawfly GenUS is now complete. Developed in cooperation with the Washington State Department of Agriculture, Sawfly GenUS is an interactive identification tool for all sawfly genera found in the United States and Canada. This tool is intended to help recognize exotic sawfly introductions and provide access to general information on affected plants, range, and diversity of these insects. This tool should be useful for port identifiers and screeners, provincial and state departments of agriculture, university extension professionals, and any non-expert with an interest in sawflies.

  • APHIS History Highlights: APHIS and Mexico Take On Deadly Screwworm

    • Apr 12, 2022
    • USDA. Animal and Plant Health Inspection Service.

    • In the early 1970s, USDA's progress in eradicating screwworm—among the deadliest and most vicious of livestock pests—was at a crossroads. Department scientists had revolutionized the country's battle against the insect by creating a new technology. The concept was simple yet profound: rear and aerially distribute masses of sterile screwworm flies in infested areas, so the resident fly populations would have increasing difficulty reproducing—and eventually breed themselves out of existence. The new approach worked so well that by 1966, USDA declared screwworm eradicated within U.S. borders.

  • USDA Takes Action to Strengthen Pollinator Research Support

    • Apr 6, 2022
    • U.S. Department of Agriculture.

    • The U.S. Department of Agriculture announced its strengthened commitment to advancing research and programmatic priorities that support pollinator health by soliciting nominations for members to serve on its newly formed USDA National Pollinator Subcommittee. The Pollinator Subcommittee will provide input on annual USDA strategic pollinator priorities and goals and will make pollinator health-related recommendations to strengthen USDA pollinator research efforts. USDA is both a major funder and conductor of pollinator research, with research initiatives spanning across five USDA mission areas.

      National Agricultural Research, Extension, Education, and Economics (NAREEE) is accepting nominations packages until May 31, 2002. Candidates selected to the Pollinator Subcommittee may serve 1–3 years with terms anticipated to start in July 2022.

  • Scientists Develop a Plan to Manage Lionfish Populations in the Mediterranean

    • Apr 11, 2022
    • University of Plymouth (United Kingdom).

    • Scientists have published a series of recommendations to enable communities and managers to minimise the impact of lionfish in the Mediterranean Sea. The invasive species was first noticed off the coast of the Lebanon in 2012, with sightings since recorded as far west as Sicily, and north into the Adriatic Sea off Croatia. More entered in 2015 due to the enlargement and deepening of the Suez Canal, with their spread unimpeded due to a lack of common predators. Researchers in the UK and Cyprus have said increasing lionfish densities – combined with the species' generalist diet and consumption of ecologically and socio-economically important fish – has the potential to result in further disruption of an already stressed marine environment. They have now published a Guide to Lionfish Management in the Mediterranean (PDF | 8.0 MB), which features a series of recommendations through which they hope lionfish populations can be managed.
