Invasive Species - What's New on NISIC's Site

ARS scientists are using a unique receptor interference technology that they have developed to target fire ants. The technology is environmentally friendly and can also be directed at other existing or emerging invasive pests to provide timely, cost-efficient pest control.

Following more than two years of consumer research and planning, the State of Illinois unveiled "Copi," the new name for Asian carp, which is a play on “copious” – as that’s exactly what these fish are. By one estimate, 20 million to 50 million pounds of Copi could be harvested from the Illinois River alone each year, with hundreds of millions more in waterways from the Midwest to the Gulf Coast. The new name and brand are designed to address public misconceptions about this delicious top-feeding fish, which is overrunning Midwest waterways.

Copi are mild, clean-tasting fish with heart-healthy omega-3s and very low levels of mercury. Increased consumption will help to stop them from decimating other fish populations in the Great Lakes and restore an ecological balance to waterways down stream.

Agriculture Secretary Tom Vilsack issued a United States Department of Agriculture (USDA) proclamation in recognition and support of National Pollinator Week -- June 20–26, 2022. Pollinator species, such as bees, other insects, birds, and bats play a critical role in producing more than 100 crops grown in the United States. Honey bee pollination alone adds more than $18 billion in value to agricultural crops annually.

USDA also released its Annual Strategic Pollinator Priorities Report: 2022 [PDF, 1.8 MB] that outlines USDA pollinator research and programmatic priorities for the coming year.

The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has announced new efforts to help prevent the introduction and spread of African swine fever in the U.S. Through an outreach and awareness campaign called “Protect Our Pigs,” APHIS will support commercial pork producers, veterinarians, and pig owners with information and resources to help safeguard America’s swine population and the pork industry.

APHIS is deploying a variety of outreach efforts to support critical stakeholders. The new Protect Our Pigs website will house materials such as downloadable fact sheets and posters, instructional videos, shareable social media graphics, a new interactive biosecurity guide, and offer the latest disease updates. If African swine fever is detected in the U.S., APHIS will also be ready to respond immediately with actionable information and resources for pig owners and the public.

In the Mexican state of Colima, a recent outbreak of the Mediterranean fruit fly, also known as medfly, was very bad news. This voracious pest was eradicated in Mexico in the 1980s with the help of FAO and the International Atomic Energy Agency (IAEA), but insects know no borders. And unfortunately, with climate change, increase of trade and global travel favouring the spread of pests, they have once more found their way into this horticulturally important state, threatening to wreak havoc on the industry and on the livelihoods of farmers. Thankfully, Mexico, FAO and the IAEA had prepared for just a scenario.

Beech leaf disease has now been confirmed in Prince William County – the first detection in Virginia. The disease affects American beech (Fagus grandifolia) trees and is associated with a foliar nematode. Symptoms include dark stripes between leaf veins, thickening and curling of leaves, and canopy thinning. Contact VDOF's forest health program if you see these symptoms. For more information, view this Beech Leaf Disease Pest Alert (Jan 2021) [PDF, 312 KB] publication.

A new botanical survey of southwest Ohio found that invasive species introduced to the United States over the past century are crowding out many native plants. Biologists from the University of Cincinnati are retracing two exhaustive surveys conducted 100 years apart to see how the Queen City's plant diversity has changed over the past two centuries. They focused their attention on undeveloped parts of cemeteries, banks of the Mill Creek and public parks that have remained protected from development during the last 200 years. The study, titled "The rise of nonnative plants in wooded natural areas in southwestern Ohio," was published in June in the journal Ecological Restoration.

Late spring heralds the start of open water fishing season. For the casual angler, it's easy to take for granted the abundance of fish this time of year. However, many species, especially native fish, can use their help. "There are so many issues affecting the health of fish populations – barriers caused by dams and roads that cross streams fragment fish habitat. Water is diverted out of streams for other uses," said Tina Hopkins, the regional fisheries program manager for the Forest Service’s Intermountain Region. "But perhaps the biggest threat across the country is aquatic invasive species."

Fisheries biologists from around the country have recommended a few ways that anglers, boaters and recreators can do their part to ensure healthy fish stocks for seasons to come. Here is their advice to recreators, in their words:

• "Consult your lawbook, know the rules, and please don’t move fish around."
• "It is extremely important that anglers clean their boats, trailers, waters, and gear when they are done fishing for the day."
• "Every drainage is going to be different, so anglers should be informed about where they are fishing."

Have you recently planted maple, crabapple, or other trees? MDAR is asking everyone to check them for spotted lanternfly egg masses or recently hatched nymphs after we were alerted that trees or shrubs with SLF egg masses may have been recently shipped to Massachusetts. Please give all nursery stock a thorough check (including pots or other containers), especially if the plants have tags that indicate they are from Pennsylvania, New Jersey, or other SLF-infested states, and report any finds.

The Entomological Society of America (ESA) is accepting comments until June 10, 2022 on a proposed common name for Vespa mandarinia and two related species of Vespa hornets.  Although Vespa mandarinia has been detected in the Pacific Northwest, the other two hornets are not known to occur in the United States.  Currently, Vespa mandarinia is being called many different names in the popular press, but no ESA authorized common name has been established. See Common Names section for more information as it becomes available.
