Illinois-Indiana Sea Grant College Program.

Much needed attention has been directed at some particularly problematic aquatic invasive species in the Great Lakes, such as Asian carps and zebra and quagga mussels. But others invaders, like crayfish, can also take their toll on the lakes. Illinois-Indiana Sea Grant (IISG) has created a new collaborative that brings together a variety of experts and stakeholders to address the threat of invasive crayfish. The Invasive Crayfish Collaborative (ICC), includes 68 experts and other stakeholders from government agencies, universities, non-profit organizations, and private businesses to combine resources and expertise to address priority invasive crayfish research and outreach needs.

The Asian longhorned tick, which preys on a variety of hosts including humans and wild and domestic animals, has been found in Kentucky. This new tick is known to attack animals in large numbers and will be a concern to livestock producers, wildlife enthusiasts and pet owners. The tick has been found in small numbers on elk in Martin County and black bear in Floyd County. It was found in large numbers on a bull in Metcalfe County in the south-central part of the state. Individuals who find a usually large number of ticks on their pet or livestock should contact their local veterinarian. Those who find single ticks they think might be an Asian longhorned tick should work with their county extension agent for agriculture and natural resources to submit the sample to UK entomologists for positive identification.

Farmers who grow cereal crops in most African countries are all too familiar with the challenges presented by striga, a parasitic plant also known as witchweed that infests farmers’ fields and causes lower yields, or even no harvest at all. Now African scientists are breeding maize that can resist this pest plant as extension agents are offering farmers various solutions for improving yields in areas where the invasive weed is especially prevalent.

University of Guam.

The University of Guam received another round of funding in September under the U.S. Department of Agriculture Plant Protection Act for the surveying and monitoring of invasive pests of solanaceous crops that are on USDA’s Priority Pest List for 2021. Solanaceae, or nightshades, are a family of flowering plants that include tomato, eggplant, and chili pepper. As part of the national effort this year, UOG was awarded $38,000 to survey and monitor for two pests: Tuta absoluta, which is a moth and type of leafminer capable of destroying an entire crop, and Ralstonia solanacearum race 3 biovar 2, which is a bacterium, known as a bacterial wilt, that infects through the roots and is deadly to plants.

The work through UOG better prepares the island to manage these invasive species if or when they arrive. "There are certain pathogens and insects that have a reputation of being really bad. These are two of them," said project lead Robert L. Schlub, a researcher and faculty member of UOG Cooperative Extension and Outreach with a doctorate in plant pathology. "They aren’t on Guam, but if they show up, we want to know so we can help get them under control."

The Great Lakes Sea Grant Network has released a comprehensive and coordinated outreach and education report on Asian carp in the region. The document includes information on carp life history, movement and behavior, monitoring, control, ecosystem impacts and gaps in current knowledge that need to be addressed further. The plan’s development was funded by the Great Lakes Restoration Initiative through the Asian Carp Regional Coordinating Committee. The final report can be downloaded here (PDF | 5.6 MB).

For the last seven decades, Cornell University’s College of Agriculture and Life Sciences (CALS) has been leading the fight against nematodes—invasive, microscopic worms that can destroy seasons' worth of crops. However, researchers had been working in a facility that lacked the infrastructure to keep pace with their innovative work. On August 1, 2019, thanks to a $1.2 million grant from New York State and another $400,000 in federal funding, CALS cut the ribbon on the new Golden Nematode Quarantine Facility, located on the Cornell campus in Ithaca, NY. The facility is the only research program in North America with expertise in biology, resistance breeding and management of potato-cyst nematodes. At the lab, Cornell scientists work in tandem with the U.S. Department of Agriculture (USDA) Agriculture Research Service (ARS).

A major tool in the fight against invasive species is the Report INvasive website, hosted by Purdue College of Agriculture and the Indiana Invasive Species Council. The website includes several ways that people can report invasive species, including a smartphone app from the Great Lakes Early Detection Network. “There are not that many specialists and experts covering the state,” Sadof said. “When there are concerned citizens reporting, however, we have many more eyes and a better chance of detecting and eradicating a harmful species early.”

North American beavers have wiped out 30 percent of forests along rivers and streams in Tierra del Fuego, a remote archipelago at the southern tip of South America, causing the greatest landscape change to these fragile forests in the last 10,000 years. It’s no surprise, then, that the governments of Chile and Argentina want the invasive beavers gone. But eradicating them has proven to be difficult, researchers found, because it requires the participation of every single landowner in the area.

New research from The University of Western Australia has shed light on why some invasive plants make a better comeback after a fire, outstripping native species in the race for resources.

The U.S. Department of the Interior has renewed its support for the Northeast Climate Adaptation Science Center (NE CASC) at the University of Massachusetts Amherst with a five-year, $4.5 million commitment as the host campus for its six-member consortium of universities, says center co-director professor Richard Palmer. Scientists affiliated with the center provide federal, state and other agencies with region-specific results of targeted research on the effects of climate change on ecosystems, wildlife, water and other resources. The new agreement continues Interior’s original seven-year, $11 million grant to the NE CASC at UMass Amherst that began in 2011. One of the web-based tools created by the NE CASC is the Regional Invasive Species and Climate Change (RISCC) Management project, which helps invasive species managers through working groups, information-sharing and targeted research.

Virginia Tech researchers who helped identify the dangerous Giant Hogweed plants in Clarke County, Virginia, want residents to stay on the lookout for the plant with toxic sap that can cause severe burns — but also stressed that the weeds are believed to have been planted intentionally decades ago and haven’t spread in the years since. Anyone who suspects they have found Giant Hogweed should take photos, check online to compare the plant to giant hogweed photos, and then contact a Virginia Cooperative Extension agent.

Virginia Tech entomologist Muni Muniappan has warned of Tuta absoluta’s likely arrival into the United States since he began monitoring the pest's spread throughout Africa in 2012. Thanks to a joint grant from the U.S. Department of Agriculture, Muniappan's team and collaborators will be able to model the pest's entry into the United States — protecting the country's billion-dollar tomato industry — before irreparable damage is caused. Tuta absoluta is a tomato pest native to South America. If left unmitigated, it has the potential to destroy 100 percent of tomato crops. In 2016, the pest caused a "tomato emergency" in such countries as Nigeria, where tomatoes are a lifeline for many smallholder farmers. With the U.S. as one of the world's leaders in tomato production, the pest's impact would be severe if nothing is done to stop it. The USDA's Food and Agriculture Cyberinformatics Tools Initiative awarded the University of Virginia's Biocomplexity Institute and Virginia Tech the four-year, $500,000 grant to project the pest's movement and rate of spread into the U.S. The model, to be developed by the Biocomplexity Institute, will map the spread of invasive species over time, accounting for factors such as climate, biology, and demographic information.
