A gypsy moth caterpillar on a leaf in Massachusetts
While being outside in Massachusetts this June, I first noticed it. A lot of leaves were falling from the trees, only these were chewed leaf parts, not whole leaves.
Similar to the children’s book, The Very Hungry Caterpillar written by Eric Carle, some leaves didn’t just have chew marks but actual holes going straight through them. Unlike the children’s book, this damage isn’t being caused by a friendly caterpillar who turns into a butterfly. Instead it’s the result of ravenous gypsy moth caterpillars feeding…and feeding. It’s so bad that in some areas, on walkways and roadways, it looks like fall. Brown, dried up leaves are a contrast to summer’s lush greenery. Read more »
An example of the damage feral swine can have on water quality.
How does the old saying go? That’s right, “Happier than a pig in mud!” Feral swine are no exception to this old farmer’s anecdote. Because they lack sweat glands, wallowing in mud and water is an instinctual behavior necessary for them to maintain a healthy body temperature. Unfortunately this behavior has cascading impacts, not only to water quality in individual streams, ponds, and wetlands, but to entire watersheds and ecosystems.
Excessive feral swine traffic around wallows and water sources causes erosion along stream banks and shorelines. Sounders, or family groups, of feral swine spend large amounts of their day around the wallow, especially in hot weather, which means they leave significant amounts of urine and feces in and around the water. The impacts to water quality go far beyond the immediate wallow site when silt, excrement, and potentially harmful pathogens, are washed down stream. Read more »

At USDA, we use a One Health approach that embraces the idea that problems arising at the intersection of the health of humans, animals, and the environment can be solved only through a coordinated multidisciplinary approach. This approach embraces the idea that a disease problem impacting the health of humans, animals, and the environment only can be solved through improved communication, cooperation, and collaboration across disciplines and institutions.
Because the One Health work that we do spans across many USDA agencies, we are launching a centralized web portal page to better help our stakeholders and the public better access our information. This page features USDA’s collective body of work on antimicrobial resistance (AMR), avian influenza and swine influenza as well as other One Health resources. Read more »
A U.S. delegation, led by Dr. Jack Shere, USDA Chief Veterinary Officer, and Dr. John Clifford, U.S. Delegate to the World Organization for Animal Health (OIE) participated in the 84th General Session in Paris, France.
International trade is a key factor in the economic and financial stability of many countries. Trade restrictions resulting from an animal disease outbreak can have devastating economic effects. With this in mind, USDA’s Animal and Plant Health Inspection Service signed three international agreements on this very topic last month at a meeting of the World Organization for Animal Health (OIE) in Paris, France. These agreements will make it easier to maintain safe and fair trade of animals and animal products if an animal disease outbreak occurs. They emphasize the cooperation and understanding of the countries involved to promote shared knowledge, data and resources, which can be crucial during an animal health event.
The three arrangements, signed by the United States, relate to the International Animal Health Emergency Reserve (also signed by Australia, Canada, Ireland, New Zealand, and the United Kingdom), the Sharing of Vaccines for Foot and Mouth Disease (Australia, Canada, Mexico, and New Zealand), and Supporting the Recognition of Zoning for Foreign Animal Disease Outbreaks (Australia, Canada, and New Zealand).

All this month we will be taking a look at what a changing climate means to Agriculture. The ten regional USDA Climate Hubs were established to synthesize and translate climate science and research into easily understood products and tools that land managers can use to make climate-informed decisions. The Hubs work at the regional level with an extensive network of trusted USDA agency partners, technical service providers, University collaborators, and private sector advisers to ensure they have the information they need to respond to producers that are dealing with the effects of a variable climate. USDA’s Climate Hubs are part of our broad commitment to developing the next generation of climate solutions, so that our agricultural leaders have the modern technologies and tools they need to adapt and succeed in the face of a changing climate.
How important will climate change considerations be in your work in the next 3-5 years? That was one of the questions USDA employees were asked in mid-April at the start of a two-day workshop at the Animal and Plant Health Inspection Service (APHIS) in Riverdale, Maryland. The hands-on training session, facilitated by APHIS’ Climate Change Working Group, the Forest Service, Northern Forests Climate Hub and the Northern Institute of Applied Climate Science, was designed to help APHIS employees from various program and support units incorporate climate change considerations into their actual projects.

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 »
