Wellington Cardoso, an undergraduate student from Brazil, arrived in Auburn, Ala., this past January to begin an internship with the U.S. Forest Service Southern Research Station where he’s been studying a biomass harvesting operation.
“The research unit has been examining harvesting technologies for short rotation woody crops,” said Dana Mitchell, project leader of the Forest Operations research unit, which is hosting Cardoso. “Cardoso’s internship ends in July, and he has been able to witness field operations in action.” Read more »

If you want to find a fungus that controls disease-spreading insects, you might want to go somewhere known for its biodiversity. So it makes sense that USDA Agricultural Research Service (ARS) microbiologist Richard Humber will be traveling to Brazil over the next three years to join Brazilian scientists in searching for fungi to control black flies, sand flies and the types of mosquitoes that spread malaria, dengue and yellow fever.
Fungi are now used to control insects on crops. Beauveria bassiana, a fungus found in soils throughout the world, is widely sold for controlling thrips, whiteflies, aphids and beetles. Different types of fungi are also sometimes used to control mosquitoes, but they are not easy to handle or to apply, and their effectiveness has been questioned. Read more »

‘Tis the season for migratory birds to make their journey north. Forests along the Pacific Flyway, which stretches from Alaska to Central and South America, recently celebrated International Migratory Bird Day with educational activities, conservation efforts and birdwatching trips.
Staff from the Mt. Baker-Snoqualmie National Forest and the Forest Service’s International Programs hosted an educational event at Camp Casey in Coupeville, Wash., that attracted 120 people of all ages who participated in interactive activities where they learned about migratory birds. In one activity, attendees took on the role of migratory birds to learn about the difficulties the birds face during migration. Their goal? To safely reach their next stop along the migration route. The first round was easy, no obstacles. The second round, a hunter was introduced and with each ensuing round, migration became more difficult. Habitats started disappearing and predators started increasing, catching larger numbers of birds. Elders, teens and youngsters alike all participated in this lively, competitive game to learn just how hard it is for birds to migrate long distances. Read more »
As an entomologist, the notion of eating insects isn’t new to me. However, for most Americans, the thought can make their stomachs churn. And yet, maybe seeing insects on their dinner plates is something Americans should get used to seeing.
Yesterday, I delivered the keynote address at the Insects as Food Conference, which was hosted by the FAO and Wageningen University in the Netherlands. As director of USDA’s National Institute of Food and Agriculture (NIFA), my goal is to ensure that the science we invest in leads to solutions to today’s most pressing challenges. One of those challenges relates to our world’s growing population, which is expected to exceed 9 billion by 2050. We need to find new ways to feed all people while minimally impacting the environment. This “9 Billion Problem” has implications for how we grow and view food now and in the future. Read more »

Everything that siblings Adán and Pilar Trujillo do on their Chimayó, New Mexico, farm connects with the community. Their lettuce and chile peppers feed students at local schools. And they sell their rhubarb, rainbow chard and red Russian kale at the community market just down the road in Española.
Conservation work helps the brother-and-sister duo make this possible. USDA’s Natural Resources Conservation Service (NRCS) is honoring contributions made by Hispanic Americans like the Trujillos to our nation during National Hispanic Heritage Month, an annual commemoration held Sept. 15 to Oct. 15.

Some say careers in agriculture are a thing of the past, but don’t tell that to Krish Jayachandran, a professor and co-director of Florida International University’s (FIU) Agroecology Program. He will tell you that agriculture is the wave of the future—and he is backing that statement with nearly a decade of work to ensure the next generation of agricultural scientists are ready.
“If we are going to feed more than 9 billion people in the future, we have to get creative in how we use our soil and water resources—not to mention our over-reliance on the same kind of germplasm decade after decade,” Jayachandran said. “I tell students that agriculture research is not farming, it is science and technology. It’s thinking about bio-geo-chemical processes and nutrient cycling; on-farm and off-farm remediation measures, surface and groundwater management, and bioenergy.” Read more »
