  • Bats on the Brink

    • Oct 27, 2022
    • USDA. FS. Southern Research Station. CompassLive.

    • USDA Forest Service researchers are monitoring the effects of white-nose syndrome, a fungal disease from Eurasia that has decimated cave-hibernating bats across the U.S. since its arrival in 2006. "The fungus that causes white-nose syndrome grows on bats in the wintertime. It causes them to wake up during their hibernation and burn their fat reserves," says Phillip Jordan, wildlife biologist. Jordan is among the experts featured in a new video, Bats on the Brink. Forestry technician Virginia McDaniel created and produced the video.

  • ARS Research News - Thrips Show Promise in Controlling the Invasive Brazilian Peppertree in Florida

    • Oct 12, 2022
    • USDA. Agricultural Research Service.

    • Brazilian peppertree thrips (Pseudophilothrips ichini) showed promise as biological control agents for invasive Brazilian peppertree populations in Florida according to a recent study published in the Florida Entomologist. Thrips are common insect pests on horticultural plants, but specialized Brazilian peppertree thrips from South America feed exclusively on the Brazilian peppertree's leaves and stem tips. Scientists from the United States Department of Agriculture's Agricultural Research Service (ARS) collaborated with University of Florida and Florida Department of Agriculture and Consumer Services researchers to mass produce and release thrips throughout 567 sites in Florida between May 2019 and December 2021.

    • The Chesapeake Bay Nutria Eradication Project (CBNEP) announced at an event at Blackwater National Wildlife Refuge today that Maryland is now free of the exotic, invasive nutria. The U.S. Fish and Wildlife Service (USFWS), U.S. Department of Agriculture’s Wildlife Services (WS), and Maryland Department of Natural Resources (DNR) have worked more than 20 years to make this difficult task -- never accomplished before on this scale -- a success.

  • Recreational Craft and Invasive Species: How to Manage Biofouling to Stop the Spread

    • Oct 13, 2022
    • International Maritime Organization.

    • Invasive aquatic species are known to be one of the biggest drivers of biodiversity loss, and their management especially in marine environments is incredibly challenging. To tackle this issue, the GloFouling Partnerships, led by the International Maritime Organization (IMO) and in collaboration with the International Council of Marine Industry Associations (ICOMIA), World Sailing, and the International Union for Conservation of Nature (IUCN), has published a new Biofouling Management for Recreational Boating Report [PDF, 13.4 MB]. The aim of the report is to stop the spread of invasive aquatic species which can adhere to hulls and other areas of recreational craft by addressing how to manage biofouling.

  • 2022 Virtual Invasive Carp Forum

    • Sep 15, 2022
    • DOI. Fish and Wildlife Service.

    • On August 9, 2022, the U.S. Fish and Wildlife Service hosted a virtual forum on invasive carp harvest and product use. This virtual event was convened in response to direction provided by Congress in the Consolidated Appropriations Act of 2022. Bighead, silver, black and grass carp – collectively referred to as ‘invasive carp’ – have been spreading in waterways across the United States and causing environmental damage since their introduction in the 1970s for use in aquaculture facilities and retention ponds. Provides access to the full recording of the forum, as well as the presentation slides.

  • Green Crab Detected in Alaska for the First Time

    • Aug 24, 2022
    • DOC. NOAA. Fisheries.

    • The green crab is an invasive marine species spreading throughout the coastal waters of the United States. Efforts between NOAA Fisheries and Metlakatla Indian Community have been leading the way on monitoring to detect this species’ presence in Alaskan waters. The green crab has been found in U.S. waters since the 1800s, but this is the first confirmed presence in Alaska. They are a serious threat for Alaska’s tidal habitats.

      If you see an invasive green crab on Annette Islands Reserve, call (907) 886-FISH to make a report. If you encounter a potential green crab elsewhere in Alaska, take photographs from multiple angles and send them to Tammy Davis. Then submit a report to the Alaska Invasive Species Reporter, or call the Invasive Species Hotline: (877) INVASIV.

  • Contributions of Classical Biological Control to U.S. Food Security, Forestry, and Biodiversity (FHAAST-2019-05) [PDF, 15.5 MB]

    • Jun 2022
    • USDA. FS. Forest Health Technology Enterprise Team.

    • Classical biological control, which reunites invasive insects or plants that have spread in new, invaded areas with their natural enemies, is the only means of reducing permanently and over large areas the harm such invaders cause. Short of eradication, which is rarely practical once an invader has spread widely, this method is the only solution that does not depend on endless control activities and their associated costs. The purpose of this book is to highlight the value that programs of classical insect and weed control have provided to the United States over roughly the last 40 years (1985–2022).

    • The Lionfish Challenge 2022, the seventh annual, is a summer-long tournament that rewards divers for their lionfish harvests. The tournament boasted a total of 707 registered participants, the most in the program’s history. 196 divers conducted a total of 676 trips throughout the state during the 3-month tournament and brought in a whopping 25,299 lionfish.

  • Strategies Identified for Successful Outreach to Reduce the Spread of Forest Pests on Firewood

    • Nature Conservancy. Don't Move Firewood.

    • Collaborative study determines effective messengers, language choices, and modes of delivery for disseminating educational information on how firewood choices can impact forest health. A recent study done in collaboration between The Nature Conservancy’s Don’t Move Firewood campaign and researchers from Clemson University showed that most people in the U.S. don’t know firewood can harbor invasive forest insects and diseases, but when targeted education materials are used effectively, they can learn and are likely to change their behavior.

  • Food Security: How Do Crop Plants Combat Pathogens?

    • Sep 22, 2022
    • USDA. ARS. Down on the Farm.

    • ARS Science Leads Way in Screening at the Molecular Level. Fungal pathogens represent a large and economically significant challenge to crops worldwide. The challenge is so great, in fact, diseases caused by fungal pathogens can cause crop losses of 10-20% (worth $100-$200 billion) each year. Historically, a variety of biological, chemical, and mechanical methods have been used to fight fungal diseases, Lately, though, researchers have focused on molecular methods to develop disease-resistant crops, which would reduce the need for, and damage caused by, chemical fungicides.
