May 18-24, 2014 is Emerald Ash Borer Awareness Week
In our efforts to preserve and protect American ash trees from the damaging and invasive emerald ash borer (EAB) beetle, APHIS is working diligently to find and implement solutions that have the potential to successfully conserve this beautiful natural resource. Spathius galinae (S. galinae) just could be that newest weapon in the arsenal.
The tiny stingless wasp, about the size of a typical mosquito, targets and attacks EAB larvae living under the bark of ash trees. Crawling along the bark ridges and furrows, S. galinae somehow senses EAB larvae hidden below. The wasp not only accurately locates its target, but also is able to determine relative size—showing preference for large EAB larvae. Once a suitable larva is detected, the female wasp uses its long egg-laying organ (ovipositor) like a hydraulic drill to bore down through the layers of bark and deposit between 5 and 15 eggs on its host. After the eggs hatch, the wasp offspring feed on the EAB larva, eventually killing it. A new generation of S. galinae emerges in about 35 days. Read more »
Under Secretary Scuse speaks with Jiisan Soybean Crusher General Manager Wang Yumin in Dalian, China.
Northeast China has been a difficult market for U.S. companies to crack in the past. The region is traditionally an area of farming and manufacturing, making it difficult to find a place for U.S. agricultural exports. But recent economic growth and development have sent the region’s agricultural imports soaring, steadily outpacing the rest of China, and American companies are taking notice. Last week, representatives from nine state departments of agriculture and 28 U.S. companies participated in a USDA trade mission to learn and explore the opportunities for trade in the region.
Under Secretary for Farm and Foreign Agricultural Services Michael Scuse led the agricultural trade mission to Dalian, Shenyang and Changchun to learn about China’s rapidly evolving market conditions and business environment. China is the largest market for U.S. food and farm products – U.S. agricultural exports to the country tripled over the last decade, now accounting for nearly 20 percent of all foreign sales of U.S. agricultural products. USDA’s trade mission to China during World Trade Month will open new doors and help farmers and ranchers capitalize on the tremendous export potential for American agricultural products. Read more »
U.S. Highbush Blueberry Council member Deborah Payne at the Gulfood 2014 trade show in Dubai, United Arab Emirates (UAE) federation.
Spring is here and brings with it many fresh healthy foods, including blueberries. Known for their antioxidants, vitamins and fiber, blueberries are a healthy option that is becoming more popular around the world and the U.S. blueberry industry is taking advantage of this demand with the help of the USDA’s Foreign Agricultural Service (FAS) Market Access Program (MAP).
Through MAP, FAS partners with U.S. agricultural trade associations, cooperatives, state regional trade groups and small businesses to share the costs of overseas marketing and promotional activities that help build commercial export markets for U.S. agricultural products and commodities.

The forests that cling to the steep slopes and cliffs of New Zealand’s Milford Sound are an example of the many pristine forest lands protected throughout the world (U.S. Forest Service/Robert Westover)
A world without forests would be pretty bleak. Life as we know it couldn’t exist. In fact it would, more than likely, be a dead planet. That’s because everything we take for granted; clean air and water, abundant wildlife and nearly every product we use in our daily lives, from the roof above our heads to pencils, wouldn’t exist.
It would be a challenge just to live one day without using a product derived from a tree. Aside from paper, you might not even be able to sit in a chair or desk at school or work. These things are part of our everyday existence because of forests.
Since trees are important for everyone around the world, the United Nations (U.N.) has designated every March 21 as the International Day of Forests. Read more »
Under Secretary Avalos is shown buildings of the south campus by Dr. Elizabeth Lautner
In February, I had the opportunity to visit USDA’s National Centers for Animal Health in Ames, Iowa. This campus hosts employees from both APHIS and ARS, who work together with tremendous collaboration. ARS employees conduct research on diseases of economic importance to the U.S. livestock and poultry industries. APHIS employees work to protect and improve the health, quality, and marketability of our nation’s animals, animal products, and veterinary biologics.
Their critical work in research, biologics, diagnostics, training, and coordination with stakeholders is impressive. It is a true science center where the work is intricate, precise, and timely. The scientific research conducted on the campus supports policy decisions, sets international standards and assures the country and the world that U.S. livestock and livestock products are safe for consumers.

New Zealand has one of the most well-developed forest biosecurity programs in the world. The logs pictured here at the Port of Tauranga were fumigated prior to export to minimize the chance of accidentally spreading forest pests. (U.S. Forest Service/Frank Koch)
Sometimes there is more to global trade than meets the eye. While consumers and economies may benefit from expanding market opportunities and a seemingly endless array of readily available goods, harmful pests could be lurking as people and products are transported between countries.
An international research network, including scientists from the U.S. Forest Service, has come together to share information about how exotic animals, diseases and plants can move and spread—and threaten agricultural and natural resources.
The International Pest Risk Mapping Workgroup consists of governmental and academic scientists from around the globe who study potential stowaway pests in order to assess the likelihood of their establishment in new locations and the impacts if and where they spread. Read more »
