Scientific Name: Struthoscelis

Common Name: Ostrich moth

Friend or Pest (or both):  Potential pest.

Region and Diet?  This moth is native to Central and South America and its caterpillar feeds on orchids in the genus Sobralia.

Impact on agriculture? ARS scientists are constantly discovering and describing new species of insects like the ostrich moth. These efforts help document the diversity of life on our planet and identify potential threats to US agriculture and our natural habitats. Orchids occur naturally in all 50 states and the orchid market is one of the fastest growing segments of the floriculture industry with a value of over $5M per year. Read the abstract to learn more about the diversity and odd morphology of these moths.

We're Looking for Innovators. Join Us!

Want to expand your science? Join us as an intern in one of our offices or professional labs and take your knowledge and experience to the next level.

USDA’s Agricultural Research Service offers internship programs to current students and recent graduates, and even Presidential Management Fellowships, to explore federal careers as paid employees. Check out the following opportunities to see best fits your career goals.

The Student Internship Program provides students in high schools, colleges, trade schools, and other qualifying educational institutions, the opportunity to explore Federal careers as paid employees while completing their education. Student Interns may be appointed for an initial period expected to last more than 1 year, on a temporary basis, or to fill traditional summer jobs. Duties are related to the intern’s academic or career goals and our positions are payable up to the GS-11 grade level.

To be eligible for the Student Internship Program, you must be accepted for enrollment or enrolled and seeking a degree (diploma, certificate, etc.) in a qualifying educational institution, on a full or half-time basis, as defined by the institution; be in good academic standing (2.0 GPA); and meet the definition of a student throughout the duration of their internship. Visit USAJobs for more information.

The Recent Graduates Program is a 1-year program that provides recent graduates an entry-level developmental experience that will lead to a civil service career. Positions are payable at the GS-09 level or below unless the position is in a science, technology, engineering, or mathematics (STEM) field. STEM positions may be payable at the GS-11 and GS-12 grade levels, depending on your educational degree.

To be eligible, you must have obtained a qualifying associate, bachelors, master’s, professional, doctorate, vocational, or technical degree or certificate from a qualifying educational institution, within the previous 2 years. Veterans who were unable to apply during the initial eligibility period due to military service obligation have a full 2-year period of eligibility upon his/her release or discharge from active duty. In no event, may a veteran’s eligibility period extend beyond 6 years from the date on which the individual completed the requirements of an academic course of study. Visit USAJobs for more information.

The Hispanic Association of Colleges and Universities (HACU) Internship Program offers a paid internship program for sophomores, juniors, seniors, and graduate students at accredited HACU colleges and universities. HACU Students are brought on board three times per year (spring, summer, and fall) and may continue year-round provided they remain eligible and program funding is available. As compensation, HACU undergraduate interns receive $610 per 40-hour week ($15.25 per hour), while graduate interns receive $680 per 40-hour week ($17.00 per hour).

To be eligible, you must have completed your freshman year before the internship begins, maintain a 3.0 GPA, be enrolled in a degree-seeking program, and be a U.S. citizen. Recent graduates are eligible if they are within 12 months of graduation. In addition, interns must attend an orientation in Washington, DC. Visit HACU for more information.

The Presidential Management Fellows (PMF) Program is designed to attract to the federal service outstanding men and women from a variety of academic disciplines and career paths who have a clear interest in, and commitment to, excellence in the leadership and management of public policies and programs.

The PMF program follows an annual cycle, starting with program announcement by the U.S. Office of Personnel Management (OPM), nomination, application and assessment, followed by appointment, through training and development, then graduation, and conversion or appointment to permanent positions.

To be eligible, you must have completed an advanced degree from a qualifying educational institution within 2 years or are scheduled to complete an advanced degree prior to the date that PMF finalists are announced. This is a competitive process in which OPM selects finalists based on an evaluation of each candidate’s experience and accomplishments. Visit OPM for more information.

If you’re a fan of salmon, you’re not alone.

The fish that was once considered a luxury food is now one of the most popular seafoods in the western world. Locally, salmon is the most popular fish species in the United States.

Scientists and staff at the Agricultural Research Service’s (ARS) National Cold Water Marine Aquaculture Center (NCWMAC) in Franklin, ME, have been improving the amount and quality of America’s Atlantic salmon for nearly 20 years.

“Since 2003, the center has worked with stakeholders to produce a North American strain of Atlantic salmon that exhibits traits producers and consumers want,” said Brian Peterson, NCWMAC research leader.

NCWMAC’s selective breeding program focuses on traits such as carcass weight, sea lice resistance, fatty acid profile, and fillet color. The center also helps North American producers compete with international producers by conducting disease and nutrition research.

According to Peterson, the NCWMAC uses traditional non-GMO breeding methods to raise about 150 families of fish each year that have been selected for improved growth and sea lice resistance. Sea lice are small crustations that attach themselves to the skin of fish and are not harmful to humans. Each year, the U.S. aquaculture industry receives a limited amount of salmon eggs from these families. These eggs are then raised by commercial farmers, who then spawn the fish that are commercially reared in net pens.

Americans consume nearly 450 tons of salmon each year, and ARS is helping keep the nets full. That’s good eatin’! – By Scott Elliott, ARS Office of Communications

Dusty rose myrtle borer
Downy rose myrtle borer. (ARS Systematic Entomology Laboratory)

Scientific Name: Casmara subagronoma Lvovsky

Common Name: Downy rose myrtle borer

Friend or Pest (or both):  Friend.

Region and Diet?  This moth is native to Southeast Asia and its caterpillar feeds on the tissues inside stems of plants in the myrtle family.

Impact on agriculture? Downy rose myrtle is an evergreen shrub from Southeast Asia that is invasive in Hawai'i and Florida. The shrub spreads quickly and can take over spaces dedicated to productive crops and plants, thereby robbing them of valuable nutrients to grow. ARS scientists teamed up to study whether this hungry moth caterpillar, also from Southeast Asia, could be used to kill and control the pesky plant. Read the abstract to learn more.

SunButter: A Tasty Spread For Sandwiches and Crackers

Sunbutter spread on a piece of bread and jars of Sunbutter next to it.

Did you know that ARS scientists developed a tasty, nutrient-rich peanut butter alternative made from sunflower seeds?  Sunflower seeds are a good source of protein, fiber, vitamin E, zinc, and iron.

Although they are a popular peanut alternative, no company had ever successfully marketed a spreadable sunflower seed butter until several years ago when Red River Commodities unveiled a new spread created with the help of the ARS Southern Regional Research Center in New Orleans, La.
