Breadfruit has been a hit in Melanesia, Micronesia and Polynesia for more than 3,000 years because of its many pluses:  This tropical staple food crop is plentiful and packed with nutrients.  It’s hailed by some as a possible solution to world hunger, but it could play a totally different—but equally important—role in saving lives.

Scientists with USDA’s Agricultural Research Service (ARS) have found that breadfruit flowers contain three chemicals that work wonderfully for repelling flying insects, including mosquitoes.  In Hawaii and other regions, people have known for years that burning dried clusters of the flowers, known as “male inflorescences,” can keep bugs at bay.

USDA Scientists Make Breakthrough in PRRS Research

This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from the USDA’s rich science and research portfolio.

Porcine reproductive and respiratory syndrome (PRRS) is a disease that costs the U.S. pork industry an estimated $664 million per year. Recently, scientists have made a breakthrough in research efforts to curb the disease.

A consortium of scientists from around the country, with funding from USDA’s National Institute of Food and Agriculture (NIFA) and Agricultural Research Service (ARS), have discovered a genetic marker in pigs that identifies whether or not a pig has reduced susceptibility to PRRS. Read more »
