A cargo ship was ordered to leave the U.S. waters after U.S. Customs and Border Protection (CBP) agriculture specialists at the Port of New Orleans discovered invasive insects found in the wood used to secure its previous cargo offloaded earlier in Mexico.

The wood used to pack the aluminum shipment was found to be infested with five separate pests, two of which required action. Two of the pests discovered pose an agricultural threat to the U.S. They were positively identified by USDA entomologists as Cerambyciae and Myrmicinae.

A framework from Rocky Mountain Research Station scientists can help managers decide if, when, and how to use eDNA sampling technology for invasive species monitoring or surveillance.

The Idaho Department of Agriculture (ISDA) has confirmed the presence of quagga mussel in the Mid-Snake River. Quagga mussel larvae was first detected in the Snake River near Twin Falls on September 18, 2023, by routine monitoring conducted by the ISDA. If nothing were done, quagga mussels would quickly take over waterways. They would irreparably harm water use in Idaho. These findings mark the first time a rapid response plan has been put into action for quagga mussels in Idaho.
 

The Massachusetts Department of Agricultural Resources (MDAR) announced today that a single dead specimen of the invasive pest known as spotted lanternfly (Lycorma delicatula) was reported and confirmed at a private residence in Boston. As a result, MDAR is urging the public to check for signs of spotted lanternfly adults in any potted plants that they may have received over the holiday season and to report any potential sightings of this pest on MDAR's online reporting form by taking photographs and collecting a specimen if possible. Residents should look for large, gray insects, about one inch long, with black spots and red underwings.

This summer, the Vermont Lakes and Ponds Program is seeking volunteers to help monitor and collect information about lakes and ponds in the state. With over 800 lakes and ponds, volunteers are key to the success of the program’s lake monitoring efforts. Volunteers can be found statewide greeting lake visitors, inspecting boats, collecting water samples, tracking algal or cyanobacteria blooms, reporting aquatic invasive species, and more. For general information, interested parties are welcome to visit the volunteer webpage.

Invasive species surveillance programs can utilize environmental DNA sampling and analysis to provide information on the presence of invasive species. Wider utilization of eDNA techniques for invasive species surveillance may be warranted. This paper covers topics directed towards invasive species managers and eDNA practitioners working at the intersection of eDNA techniques and invasive species surveillance. It provides background information on the utility of eDNA for invasive species management and points to various examples of its use across federal and international programs.

Northern pike are native to Alaska, Canada, and much of the central and eastern continental United States. Genetic evidence reveals the role of human transport in the spread of invasive northern pike in the Columbia River basin.

For 21 consecutive years, researchers from the USDA Forest Service and partners at North Carolina State University have tracked the status and trends of forest health across the U.S.  Annual assessments of forest health are key to understanding whether year-to-year changes are part of longer-term trends.  Forests constantly change because of tree mortality and growth, weather events and climate trends, and disturbances from stressors including fire, insects, and diseases.

The Early Detection and Distribution Mapping System (EDDMapS) is a Web-based mapping system for documenting invasive species distribution. The majority of invasive species reporting in the U.S. occurs through or in cooperation with EDDMapS.

The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) is asking the public to look for and report the Asian longhorned beetle (ALB). APHIS declares every August Tree Check Month and is asking you to look for this destructive, invasive beetle by checking trees on your property and in your community for damage. Left unchecked, the ALB can cause infested trees to die. August is an ideal time of year to look for the beetle and the damage it causes.
