ARS scientists at the Plum Island Animal Disease Center in Orient Point, NY, have made two important advancements against African swine fever virus, which causes a lethal disease in pigs.
After being disbanded in 2019, newly appointed members of the Invasive Species Advisory Committee (ISAC) gathered this week to discuss strategies to prevent, eradicate and control invasive species, which impose substantial costs on society and cause damages that impact the global economy, including an estimated $120 billion in environmental damages and losses annually in the United States.
Feral swine can carry foreign animal diseases like African Swine Fever. While ASF has never been found in domestic or feral swine in the United States, there is no treatment or vaccine for it. That’s why surveillance is very important. Help protect U.S. pigs by immediately reporting sick or dead feral swine.
WHAT TO DO: If you find a sick or dead feral swine with no obvious injury or cause of death, report it right away. Call the USDA-APHIS Wildlife Services program in your State at 1-866-4-USDA-WS. Don’t wait! Quick detection is essential to preventing the spread of ASF.
Scientists with the U.S. Department of Agriculture's Agricultural Research Service (ARS) announced that a vaccine candidate for African Swine Fever (ASF) passed an important safety test required for regulatory approval, moving the vaccine one step closer to commercial availability.
Humans adores trees. But humans also migrate and trade, habits that led to the accidental introduction of insects and diseases that harm trees and alter the landscape. Examples are easy to find and may be outside your front door: American elms that once dotted streets across America succumbed to Dutch elm disease. Now all colors of ash species – black, green, white, pumpkin, and blue – are threatened by emerald ash borer. The already uncommon butternut tree, also known as white walnut, faces the possibility of extinction from a mysterious attacker. Many invasive insects and fungi come from regions where native trees have evolved to resist their attacks. When these species enter the United States, they find trees that lack this resistance. There's no immediate end to this dismal pipeline, but there is hope on the horizon.
USDA's Agricultural Research Service (ARS) is rolling out Tellus, its new online communications platform, replacing its legacy AgResearch online magazine. ARS is committed to sharing the stories of its scientists and their successes and looks forward to informing and entertaining viewers about the many ways ARS’ revolutionary research impacts the growing world.
Agricultural Research Service (ARS) scientists are tracking a honey bee killer, and their investigations have taken them from hives in Tucson, Arizona, to Bismarck, North Dakota. Led by ARS entomologist Gloria DeGrandi-Hoffman, the team is staking out hive entrances and monitoring the comings and goings of foraging honey bees, which may be the killer's unwitting accomplices. None of the busy little winged bearers of pollen and nectar will get by without inspection: The prime suspect—an eight-legged, pinhead-sized parasite called the Varroa mite—seems to be sneaking into the hives on the bees' bodies. The Varroa mite, Varroa destructor, is considered public enemy number one to honey bees nationwide. The parasite feeds on the blood of adult bees and their brood, weakening them and endangering the entire hive when infestations become severe. But the mite also poses an indirect threat to more than 90 flowering crops that depend on bee pollination, including almonds, apples, blueberries, cherries, and cantaloupes.
Along the Rio Grande in Texas, tiny insects are taking a big bite out of an invasive weed that competes for limited water resources vital to agriculture and native vegetation. Several years ago, ARS scientists released two insect species as part of a biocontrol program to kill giant reed (Arundo donax).
Emerald ash borer (EAB) is an invasive insect from Asia that kills ash trees. EAB was first detected in North America in 2002. Several tiny wasp species are helping to control EAB.
Agriculture Secretary Tom Vilsack today applauded research and protection efforts underway at the U.S. Department of Agriculture’s (USDA) Agricultural Research Service (ARS) and Animal and Plant Health Inspection Service (APHIS) to prevent the spread of African Swine Fever virus, which has been causing devastating losses to the swine industry across the globe. "USDA agencies are working together to protect U.S. livestock from foreign and emerging animal diseases that could harm our economy and public health," said Secretary Vilsack. "I am proud of the extraordinary research underway at the Agricultural Research Service to develop vaccine candidates to prevent African Swine Fever virus. In addition, the Animal and Plant Health Inspection Service has done tremendous work to establish protection zones to safeguard the entire U.S. swine industry."
African Swine Fever (ASF) was originally detected in 2007 in the Republic of Georgia and is known to cause virulent, deadly disease outbreaks in wild and domesticated swine. Since the original outbreak, ASF has had a widespread and lethal impact on swine herds in various countries in Eastern and Central Europe and throughout Asia. Although the virus is causing profound economic losses to the swine industry, there have not been any U.S. outbreaks.
Predicting the next invasive species allows us to take action before they reach our waterways—an economically and environmentally smarter approach than responding after they’ve arrived. To get a jump on potential invaders, scientists have developed methods that pinpoint the risk a species poses to specific environments based on factors like history of invasion, its ability to survive in similar habitats, and how difficult it is to control. Using these tools and the information they provide, natural resource managers, environmental educators, and individuals who buy and sell live aquatic organisms can make more informed decisions on how to protect their waterways from potential AIM.
