Along the Rio Grande in Texas, tiny insects are taking a big bite out of an invasive weed that competes for limited water resources vital to agriculture and native vegetation. Several years ago, ARS scientists released two insect species as part of a biocontrol program to kill giant reed (Arundo donax).
Prevention is the most effective strategy in managing invasive species. However, hundreds of invasive plants and animals have already established in California and are rapidly spreading each year. These invaders are negatively impacting our waters, our native plants and animals (some of them rare, threatened, or endangered), our agriculture, our health, our economy, and our favorite recreational places. Help us celebrate California's Invasive Species Action Week, and more importantly, help stop the spread of invasive species, by volunteering to take action.
DHS. Customs and Border Protection.
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.

ARS scientists in Nevada, studied ways to control cheatgrass and restore rangelands to a healthy mix of plants, which in turn reduces wildfire threats, supports wildlife, and increases sustainable grazing resources.

In parts of the South, there are stories about an invasive floating weed, which forms such a dense mass that it enables small animals to walk across water. This weed, called giant salvinia, is an exotic fern from South America that invades ponds, lakes, and other waterways in the United States. It damages aquatic ecosystems by outgrowing and replacing native plants that provide food and habitat for native animals and waterfowl.
Agricultural Research Service (ARS) scientists are testing a naturally occurring fungus (Myrothecium spp.) against giant salvinia to help control it. Initial tests have found that the fungus stops this problematic weed from growing and even can kill it.
State of Wyoming.
Reflecting his goal of making Wyoming a national leader in the battle against invasive species, Governor Mark Gordon announced today he has launched an initiative to address terrestrial invasive plants in the state. The initiative will be comprised of two teams -- a Policy Team and a Technical Team, each comprised of local, state and federal government representatives, private citizens representing industry and agricultural groups, as well as scientists and practitioners. The two teams will work cooperatively to develop recommendations for the Governor in the context of a large-scale strategy for invasive species management. Terrestrial invasive species represent a significant threat to Wyoming’s forests, rangelands and agricultural lands with varying levels of impact.
USDA. ARS. Tellus.
Rodrigo Krugner, an entomologist with the Agricultural Research Service (ARS) in Parlier, California, has found an innovative way to control insect pests in California vineyards: tapping into the vibrational signals they use as mating calls.
Krugner’s efforts have mainly focused on glassy-winged sharpshooters, which spread a bacterium that causes Pierce’s disease in vineyards and costs the California grape industry an estimated $104 million a year. Growers use chemical sprays to control the pests, but insecticides also kill beneficial insects, leave residues, and become less effective as the insects develop resistance.

The NPS is working to manage invasive species on park lands through a suite of national and local programs including the NPS Invasive Plant Program (IPP). This strategic plan sets the course for the IPP by articulating a mission, vision, goals, and actions for the next ten years with near-term goals that will be reported on and revisited annually. The plan will guide annual work planning and major projects and identify and help prioritize program funding needs and initiatives.

Hunting for natural enemies of the red imported fire ant is paying off for Agricultural Research Service (ARS) scientists. Their latest discovery — a new virus found in fire ants from Argentina — has the potential of becoming a biological control agent against the red imported fire ants infesting the U.S.

Watercraft Inspection and Decontamination Programs - Many Western states instituted watercraft inspection and decontamination programs after the discovery of invasive mussels in Lake Mead in 2007. This section provides resources on mandated watercraft inspection and decontamination programs, as well as some non-mandated but state-funded watercraft inspection efforts.
Aquatic Invasive Species Decals - Some U.S. states require that boaters purchase an aquatic invasive species decal (sometimes called a stamp, sticker, or permit) before operating watercraft in that state. Many of these regulations were instituted as a response to the spread of zebra and quagga mussels into the Western U.S. Fees from the purchase of these decals are typically used to fund local aquatic invasive species outreach and prevention activities.
