The U.S. Department of Agriculture's (USDA) Animal and Plant Health Inspection Service (APHIS) and the Clemson University's Department of Plant Industry (DPI) are inspecting trees in Hollywood, South Carolina following the detection and identification of the Asian longhorned beetle (ALB). Tree inspectors from APHIS and DPI are surveying trees in the eastern portion of Hollywood around the property where ALB was found. Inspectors will ask for permission from residents to survey trees on private properties before they conduct surveys. Residents who live in the town of Hollywood can help by allowing officials access to their property to inspect trees. Residents can report the insect or tree damage by calling the ALB hotline at 1-866-702-9938 or reporting online at www.AsianLonghornedBeetle.com. South Carolina is the sixth state to detect an Asian longhorned beetle infestation. The beetle has previously been found in New York, New Jersey, Illinois, Massachusetts, and Ohio. Infestations have been eradicated in New Jersey and Illinois, and eradication efforts continue in New York, Massachusetts and Ohio.

Potatoes and oak trees don’t have a lot in common, but there is one thing, and it isn’t good – a fungal-like plant pathogen in the genus Phytophthora. One of the many invasive pathogens contained in this genus, P. infestans, was responsible for the Irish potato famine. Since the mid-1990s, though, Phytophthora has been attacking forest trees along the West Coast, with the pathogen P. ramorum, also known as "sudden oak death" (SOD). SOD was first detected in the San Francisco Bay Area; it has since spread throughout California. In 2001, SOD was discovered in southwest Oregon where it infected tanoaks trees. The discovery led to the formation of an interagency team that included researchers from the Agricultural Research Service (ARS) and Oregon State University (OSU), to develop strategies to mitigate the impacts of SOD.

A tiny wasp may be the solution for managing an agricultural pest causing major economic damage to fruit, vegetable, and field crops in North America and Europe. Agricultural Research Service (ARS) scientists are currently studying Trissolcus japonicus, commonly known as the samurai wasp, to see if this parasitoid wasp is the right biological control agent for reducing brown marmorated stink bug (Halyomorpha halys) (BMSB) populations outside of Asia. Biological control is the process of reducing or mitigating pests or pathogens by using the pest’s or pathogen’s natural enemies. The samurai wasp is a known natural enemy for the BMSB in Asia, and researchers are understanding how it behaves in non-native environments.

New techniques use radiation to eliminate dangerous mosquitoes. The Aedes aegypti mosquito is notorious for spreading dengue virus, yellow fever virus, chikungunya virus, and Zika virus, among other ailments. While many mosquitoes do not feed on people, or even domestic animals, this mosquito targets humans causing disease to millions of people throughout the world. ARS researchers with scientists from the University of Florida have developed a new technique for using radiation to control mosquito populations.

Spotted-wing drosophila (Drosophila suzukii), is an invasive fruit fly species that causes about $500 million in economic damage to fruit crops in the U.S. each year. A native to southeast Asia, it arrived in the U.S. in Hawaii in the 1980s and in the continental U.S. in California in 2008. It is now widespread through many parts of the U.S. and the world. In a new review article published last week in the Journal of Economic Entomology, Vaughn Walton, Ph.D., of Oregon State University and a multi-university team of experts have created a comprehensive look at how SWD management strategies are evolving to address these challenges.
The U.S. Department of Agriculture grant that funds part of Walton and colleagues SWD research stipulates that they work with industry influencers, and they have been doing this from the beginning. They bring technologies to industry and seek feedback on how well the technologies work in actual practice. "Federal funding is allowing us to listen to and serve our clients—the growers," Walton says. As the Journal of Economic Entomology paper details, many promising control strategies are being developed for this challenging and uniquely adaptable invasive species. With continued advances, researchers can hope that populations of SWD can be controlled and the damage they cause reduced.

The arid and semiarid Great Basin of the western United States comprises parts of California, Nevada, Utah, Idaho, and Oregon and can variously be described by its hydrology, topography, or biology. Biologically, the area has been defined historically by the native sagebrush and shrubs that thrive in the dry valleys of the Sierra Nevada and Cascade Mountains. But, as a recent study undertaken by researchers at the University of Montana and the Department of Agriculture notes, these native plant communities are rapidly being colonized by nonnative annual grasses like cheatgrass (Bromus tectorum), red brome (B. rubens), and medusahead (Taeniatherum caput-medusae) to the detriment of wildlife and humans.

How can an insect that is smaller than a penny cause so much ecological, economic, and cultural devastation? The emerald ash borer, an invasive beetle native to Asia, is one of the most destructive invasive species in North America. These tiny pests killed tens of millions of ash trees in the northeast – and continue to this day.
In Maine, a coalition of Indigenous and non-Indigenous researchers, tribal members, state and federal foresters, conservation groups, and local communities have been working for the past twenty years to prepare for the onset of emerald ash borer in northeastern forests. The group, called the Ash Protection Collaboration Across Wabanakik, is focused on identifying research-informed strategies to protect the future of ash trees.

Over recent decades, globalization has led to an increase in the international flow of people and goods, bringing people together but also bringing together species that have never coexisted before. Species that are introduced and successfully colonize areas outside their natural ranges are considered ‘invasive’ and can have devastating impacts on species native to the region. Invasive species can cause the decline or extinction of native species, outcompeting them for food, water and space, preying upon them or introducing them to new diseases.

In an effort to monitor invasive northern snakeheads in the Chesapeake Bay and Blackwater River, the Maryland Department of Natural Resources (DNR) announces a new tagging program in conjunction with the U.S. Fish and Wildlife Service (USFWS). Both agencies are placing yellow or blue tags on up to 500 northern snakeheads. Each tagged northern snakehead caught and harvested from now until 2024 could be rewarded with a gift card of $10 or $200 depending on the tag.
In order to qualify, the harvester must report the tag number to USFWS at 800-448-8322, and is asked to take a picture of their harvested and tagged northern snakehead. Only harvested northern snakeheads with reported tags will qualify for gift cards.

Foot-and-mouth disease (FMD) virus spreads much more aggressively in pigs than previous research suggests, according to a new study by U.S. Department of Agriculture (USDA) scientists. The study, recently published in Scientific Reports, shows that pigs infected with the FMD virus were highly contagious to other pigs just 24 hours after infection—long before showing any clinical signs of infection such as fever and blisters. Foot-and-mouth disease continues to be the most important foreign disease of livestock worldwide, said Jonathan Arzt, lead investigator and veterinary medical officer with USDA’s Agricultural Research Service (ARS). Although the United States has not had an FMD outbreak since 1929, this highly contagious viral disease, which is sometimes fatal, is still considered a serious threat to U.S. agriculture.
