Students Intrigued Enough to ‘Worm’ Their Way into Ag Science

Future Scientists Program teachers in the field with ARS research entomologist John Goolsby

Future Scientists Program teachers in the field with ARS research entomologist John Goolsby, learning about his research on bio-control for Giant Reed (Arundo donax) in the Rio Grande Valley.

The goal of USDA’s Hispanic-Serving Institutions National Program (HSINP) Future Scientists Program is to enhance the scientific knowledge of teachers, helping them to become more effective in encouraging student interest and progress in science. Teachers in the program attend two-day summer institutes at Agricultural Research Service (ARS) labs nationwide, where scientists introduce them to various research projects. ARS researchers share scientific knowledge with the teachers, who then share it with their students to encourage them to become future scientists.

One of the catalysts for this lofty goal is a tiny, inconspicuous and innocuous caterpillar—the corn earworm that wreaks havoc in corn fields nationwide as an agricultural pest.  This program began in 2003.  I brought 10 teachers into the ARS Southern Plains Agricultural Research Center (SPARC) in College Station, Texas, for a summer institute that included teachers studying in corn research plots searching for corn earworm caterpillars in 100-degree heat! It was the first time I made caterpillars the focus of this program.

O Halloween, Arachnophobia, Entomophobia, and Why Insects Exist

Wolf spiders are robust and agile hunters with excellent eyesight. They live mostly solitary and hunt alone. (Bugwood.org/Joseph Berger)

They squirm, crawl, scurry and swarm … and they’re all around us.

More than 900,000 species of insects and arachnids are found around the world, and some people would rather not come into contact with even one of the often misunderstood critters.

The fear for me came when I was 7 years old during the summer of 1990. Read more »

Evening Primrose by any Other Name is a Moth Plant

Plants provide us with many things that we use on a daily basis – from the buildings in which we live and work, to our clothing and food. For flowering plants to thrive and reproduce, they often rely on pollinators to transport pollen between flowers.

Pollination ultimately results in fruits and seeds, ranging from the strawberries and almonds in your breakfast to the tomatoes in your pasta sauce. While scientists know a lot about honeybees, very little is known about many other pollinators – bats, birds, bees, butterflies, moths, flies, etc. – that are essential to pollinating wildflowers and native plants.

Moths Aflutter in Honor of National Moth Week

The luna month (Actiasl luna) have pale green wings with long curving tails and a wing span of roughly 3 to 4 inches. They are strong fliers with an attraction to light and can been seen, depending on the area of the country, between May and September. (National Park Service)

Imagine wandering through your favorite botanic garden in the early evening and catching a glimpse of the moon reflected off of something lime green that moves from flower to flower while closer to the ground the yellow glow of fireflies help illuminate the night.

It’s enough to make you feel like you’re in a Shakespearean forest.

But the lime green is really the wings that belong to what some consider the most beautiful insect – the Luna moth. Those who do catch a glimpse of this unique moth are lucky – as they are rarely seen due to their short life span. Read more »

New International Wood Packaging Standard Stops Bugs Dead in their Tracks

Several hundred non-native forest insect species have become established in the U.S. Recent arrivals, such as this adult Asian longhorned beetle, have killed millions of trees and altered urban landscapes in the Northeast and Midwest.

Wood makes great packaging material—it’s inexpensive, abundant and versatile—but there’s one drawback: destructive forest pests stowaway in the pallets, crates and dunnage (wood used to brace cargo) used in international shipping. Over many years, international trade has resulted in the inadvertent introduction of many non-native wood-feeding pests and plant pathogens in the U.S. and throughout the world. Some of these non-native insects, including the emerald ash borer and the Asian longhorned beetle, have become highly invasive and caused serious environmental and economic impacts.

But an international standard for wood packaging material is slowing the inadvertent export of invasive bark- and wood-boring insects, according to a study conducted by Robert Haack, a research entomologist with the Forest Service’s Northern Research Station in Lansing, Mich., and a team of scientists. Researchers found as much as a 52 percent drop in infestation rates in the U.S., where the standard was implemented in three phases between 2005 and 2006. The study was published May 14 in the journal PLOS ONE. Read more »

Insects for Dinner? Potential Tool in the Toolkit to Achieve Global Food Security

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 »
