Scientists May Have Found A Way To Save Our Trees!

Scientists, from the University of Minnesota, have discovered a possible path forward in controlling the emerald ash borer (Agrilus planipennis). Since its introduction, this pest has become the most devastating invasive insect in the United States, and has killed hundreds of millions of ash trees.
In a recently published study, researchers identified various fungi living in emerald ash borer-infested trees. Through DNA sequencing, they identified types of fungi that will attack insects. They also found other types of fungi that cause cankers – which help kill trees that are infested with these pests.
“We discovered that several different species of fungi attack the emerald ash borer and other insects, and they can now be further tested for their potential biocontrol,” said Robert Blanchette, the study’s project leader. “This is a very important step in the search for a biocontrol for the emerald ash borer.”
The scientists will continue building on their work to determine if any of the fungi can be used to kill the emerald ash borer.
“Ash trees are vitally important to Minnesota,” said Rob Venette, director of the Minnesota Invasive Terrestrial Plants and Pests Center. “They reduce air pollution, storm water runoff, and cooling costs, all while increasing property values in local communities. It’s critical we work to protect them from invasive pests.”
