The streamlined design of Oobinator 2.0 improved the distribution of the wasps—each Oobinator containes 50 wasps that could be positioned at four distinct locations throughout the field site. Stingless wasps disperse in the field to search for EAB eggs that will serve as a host for its offspring.
Emerald ash borer (EAB) beetle is an invasive wood boring beetle, first detected in July 2002 in southeastern Michigan. The pest attacks and kills ash trees and it is responsible for the death and decline of tens of millions of ash in 25 states. EAB lives under the bark and when people move EAB-infested firewood they unknowingly move the pest. During EAB Awareness Week (May 22-28) leave HungryPests behind and don’t move firewood.
Do you remember the eighties television show MacGyver? Science genius turns secret agent. Each week Angus MacGyver—armed with only a pen, aerosol spray can and a Swiss Army knife—successfully disarms the bomb and saves the day! The following week, it’s a shoe horn, jumper cables and a screwdriver…then a thermos, belt buckle….you get the drift. Sixty minutes of ingenious, nail-biting problem-solving.
Although the show’s final episode aired almost 25 years ago, the spirit of Angus lives on at the USDA’s Emerald Ash Borer (EAB) biological control production facility, where USDA is strategically rearing natural enemies to combat this destructive pest. Mass rearing biocontrol agents (stingless wasps) is a delicate process that’s time-sensitive, labor-intensive, and laden with problem-solving opportunities. Read more »
Smokejumpers join the search for Asian longhorned beetles.
Smokejumpers are a unique breed. They are people who are willing to jump, really parachute, out of an aircraft to provide a quick attack on forest fires. While smokejumpers are highly trained, experienced firefighters, they are also expert tree climbers. These firefighters usually work in rugged terrain, but travel all over the country to fight fires. Recently they traveled to Tate Township, Ohio to fight a fire of a different kind.
In April, the U.S. Forest Service sent smokejumpers to help the USDA’s Animal and Plant Health Inspection Service (APHIS) combat the Asian longhorned beetle (ALB) by climbing trees in Tate Township, Ohio, about 40 minutes outside of Cincinnati. The beetle is destroying trees in this area and the goal is to find infested tree quickly before the insect starts to emerge in May as adult beetles from the inside infested trees. Read more »

All this month we will be taking a look at what a changing climate means to Agriculture. For APHIS, changes in environmental conditions will increase the likelihood of shifts in the distribution and nature of current domestic diseases, invasive species and agricultural pests. These changes will likely influence the dynamics of invasion and establishment of these diseases and pests, and therefore much of APHIS’ work. Understanding and adapting to these changes is therefore critical to meeting our mission.
Vampire bats rank high on the list of animals that scare us the most. Spooky Halloween tales of their blood-sucking, nocturnal, and secretive habits have likely led to their bad reputation. The fact that some also carry and spread the deadly rabies virus doesn’t help.
The common vampire bat feeds on the blood of Central and South American wildlife and livestock. They also sometimes bite and feed on the blood of people. Recently, vampire bats have been documented within 35 miles of the Texas border. This has caused concern and speculation about the potential movement of vampire bats to areas within the United States as a result of rising global temperatures. To gain a better understanding of the likelihood of such movement, USDA-APHIS geneticist Dr. Toni Piaggio with the Wildlife Services National Wildlife Research Center partnered with U.S. Geological Survey scientist Dr. Mark Hayes to analyze and map the potential distribution of vampire bats under various climate scenarios.

The new face of USDA/APHIS Veterinary Medicine, Dr. Jack Shere, is also a familiar one.
Dr. Jack Shere, a long-time employee of USDA’s Animal and Plant Health Inspection Service (APHIS), was recently named USDA’s Chief Veterinary Officer leading APHIS’s Veterinary Services program.
Dr. Shere joined APHIS in 1990 and has held a variety of field and leadership positions – serving as the area commander during the exotic Newcastle disease outbreak in 2003 and spending many weeks in Iowa during the 2015 Highly Pathogenic Avian Influenza outbreak where he represented USDA and Secretary Vilsack. Dr. Shere also spent several years in private veterinary practice prior to joining APHIS. Read more »

Spring brings new life to the fields and forests and wild turkeys are one of the most interesting spectacles this time of year. Male turkeys gobble and strut to attract the attention of hen turkeys. Hens, in turn, go off and lay their eggs- one egg each day until the clutch is complete and the hens then begin incubation.
Unfortunately, this spring more than ever, wild turkeys across the U.S. are facing an increasing threat from a new and rapidly expanding population of nest predators…feral swine. Feral swine, also known as wild pigs, feral hogs, and wild boars, are not native to North America and are the descendants of domestic swine which either escaped or were liberated. In some cases, feral swine are intentionally released to create new hunting opportunities. But these opportunities come at the expense of other wildlife, including ground nesting birds such as the wild turkey. Feral swine are highly adaptable and can learn to seek out turkey nests even before the hen starts incubation, consuming the eggs when left unprotected. When a partially completed clutch is depredated, the hen is forced to start over, depleting vital reserves within herself as well as risking lower nest success and chick survival. Read more »
The first U.S. dairy cattle shipped to Pakistan in 17 years are loaded onto trucks for their journey to the FAS-supported demonstration farm at the University of Veterinary and Animal Sciences near Lahore.
U.S. dairy cows are back in Pakistan for the first time in 17 years. More than 300 heifers arrived in Punjab Province on March 2, thanks to the efforts of USDA’s Foreign Agricultural Service (FAS). It’s hoped the shipment will be the first of many from the United States and will provide a better breed of cow for the rapidly growing Pakistani dairy industry.
Most of the dairy cows have been purchased by commercial dairy farms, but 73 Holsteins in the shipment will be delivered to a new model dairy farm that FAS has established to support the rapidly growing Pakistani dairy industry and create new opportunities for U.S. exporters. Read more »
