The participant who harvests the most lionfish will be crowned the Lionfish King/Queen. The Challenge is open now and will run through November 1. You can register for the 2020 Lionfish Challenge and find more information at FWCReefRangers.com/Lionfish-Challenge. Questions regarding the challenge can be sent to Lionfish@MyFWC.com.

The U.S. Geological Survey has released a comprehensive synthesis of Burmese python science, showcasing results from decades of USGS-funded research on python biology and potential control tools. The giant constrictor now represents one of the most challenging invasive species management issues worldwide.

Scientists from the Connecticut Agricultural Experiment Station (CAES) are reporting that Beech Leaf Disease (BLD) has increased dramatically in both severity and distribution in 2022 compared to 2021. First detected in lower Fairfield County in 2019, BLD is now widespread on American beech (Fagus grandifolia) throughout all eight Connecticut counties, with symptoms most severe in Fairfield, New Haven, Middlesex and New London Counties. Given that BLD is now widely established throughout Connecticut, reports of BLD to CAES and DEEP are no longer requested.

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).

Ailanthus altissima (tree-of-heaven) is a rapidly growing invasive tree species introduced to the United States nearly 200 years ago. Today, this species is a common invader in many forests across the nation. Scientists with the Northern Research Station have identified a unique biological control measure for managing Ailanthus—Verticillium nonalfalfae, a native soil-borne fungus. Check out this latest issue of Rooted in Research that explores how Verticillium can reduce Ailanthus populations.

Climate change is having an important influence on invasive species. The increase in temperatures, rainfall, humidity and drought can facilitate their spread and establishment, creating new opportunities for them to become invasive. For additional information, see the following CABI resources:

Researchers have been working on a solution to fight citrus greening disease and may have found one in the unique antibodies found in camels, llamas, and alpacas.

Colorado Parks and Wildlife (CPW) announces additional zebra mussel veligers found in the Colorado River and Government Highline Canal after increased testing. With these additional detections, both the Highline Government Canal and the Colorado River meet the criteria for being considered “positive” for zebra mussels.

Louisiana is home to some of the most destructive invasive species found in the United States. The LSU AgCenter has long worked to monitor and manage these non-native insects, weeds and wildlife. To better understand and control invasive species, the LSU AgCenter is developing a Center of Research Excellence for the Study of Invasive Species. The Louisiana Board of Regents approved the creation of the center on Sept. 20.

Early detection is critical to the eradication and management of invasive species, and curious members of the public play a key role by sharing observations on platforms such as iNaturalist. Integrating these sightings from a bug-curious public into ongoing biosecurity surveillance is an increasingly valuable approach for invasive species management.

ARS researchers use biocontrol methods to manage fire ant populations.

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.

Forests are incredibly important to pollinators. Forest pollinators can also provide substantial economic benefits to neighboring agricultural areas, as a new global review paper discusses. Forest pollinators are easy to overlook – they are often highly seasonal, especially in temperate regions, and many are active far above our heads in the forest canopy.

On June 1, a new regulation was published in the Delaware Register of Regulations (Volume 26, Issue 12) listing potbellied pigs and feral swine of any kind as invasive. The Delaware Department of Agriculture (DDA) is providing a 30-day grace period for potbellied pig owners to apply for an Invasive Animal Permit. Owners have until August 12 to submit an application and comply with 3 DE Admin. Code 906 Possession, Sale, or Exhibition of Non-Native and Invasive Animal Species.

The Maryland Department of Agriculture has confirmed the first spotted lanternfly hatch of 2020. The first instar nymph of the season was reported by a department employee while surveying for the pest in the upper northeast corner of Cecil County near the Pennsylvania border.

See additional resources on the Maryland Department of Agriculture's site for Spotted Lanternfly for up-to-date information.

The Maryland Department of Agriculture (MDA) expanded its spotted lanternfly quarantine.  A quarantine order first issued by the state secretary of agriculture in October 2019 for Harford and Cecil counties is still in effect, but has been expanded this year to also include: Anne Arundel, Baltimore, Carroll, Frederick, Howard, Kent, Montgomery and Washington counties, as well as Baltimore City. This quarantine is effective immediately, and restricts the movement of regulated articles that might contain the spotted lanternfly in any of its life stages, including egg masses, nymphs, and adults.

See additional resources on the Maryland Department of Agriculture's site for Spotted Lanternfly for up-to-date information. For questions related to the quarantine, permitting, treatment, or to report a sighting of the spotted lanternfly, especially outside of the quarantine zone, call 410-841-5920 or email DontBug.MD@maryland.gov. If you report a spotted lanternfly via email, please provide the location of the sighting and your contact information.

The National Detector Dog Training Center trains specially selected dogs and their handlers to safeguard America’s agricultural and natural resources from harmful pests. These dog teams carry out a range of activities, from inspecting passenger baggage, cargo, and parcels at ports of entry to detecting certain invasive species in the environment. Together, they help protect our Nation's food crops, forests, farms, and environment.

Detector canines—trained by USDA's Plant Protection and Quarantine (PPQ) program—are ready to sniff out these damaging invasive pests to detect them early and prevent their spread. These highly trained dogs represent some of the recent successes of our Agricultural Detector Canines strategic initiative. Its goal is to expand the use of detector dogs to enhance domestic pest surveys, detect pests early, and facilitate the trade of U.S. agricultural products.

Farmers in the southeastern U.S. struggle with the invasive guava root-knot nematode, a microscopic roundworm, which infects and damages a variety of crops, particularly sweetpotatoes. To combat this worm, ARS researchers at the U.S. Vegetable Laboratory in Charleston, South Carolina, have identified a sweetpotato line from the agency’s expansive germplasm collection that has shown high levels of resistance to the guava root-knot nematode as well as resistance to other crop insects.

A 4-H student presenting a project at the Kansas State Fair has inadvertently triggered a state and federal investigation into a nasty, unwelcome bug. The student found the spotted lanternfly in Thomas County in western Kansas and included it in a 4-H entomology display.

The Georgia Department of Agriculture (GDA) announced, in coordination with USDA and the University of Georgia, confirmation of the detection of a living yellow-legged hornet (Vespa velutina) in Savannah, Georgia. This is the first detection of a live yellow-legged hornet in the open U.S., which was confirmed on Aug 9, 2023. GDA is asking the public to report any sightings of the yellow-legged hornet, a non-native hornet species, that, if allowed to establish in Georgia, could potentially threaten honey production, native pollinators, and our state’s number one industry - agriculture. See more information about the yellow-legged hornet, including how to report sightings.
