Scientists Draft a Natural Nemesis to Combat Invasive Tree-Killing Beetles

Cody Sullivan, June 9, 2016 at 10:15am

The emerald ash borer, an invasive beetle from Asia, is blitzing ash trees in urban and forested ecosystems across North America. To date, this metallic green beetle has attacked and killed hundreds of millions of ash trees in 25 states, and its spread continues. To control this beetle, the U.S. Department of Agriculture (USDA) is using biological control, a long-term sustainable management tool that involves the introduction of specialized natural enemies from a pest’s native region.

In December 2013 when Sarah Jovan and Geoffrey Donovan, two scientists with the U.S. Forest Service’s Pacific Northwest Research Station in Portland, Oregon, crisscrossed the northwest area of their city they had no idea they were onto something big.

Moss growing on urban trees, such as this species sample of Lyell’s orthotrichum, is a useful bioindicator that can help monitor cadmium, a carcinogenic heavy metal, in the air.

In mid-April, scientists and staff at the U.S. Forest Service Coweeta Hydrologic Laboratory hosted theStrategies for Ecological Education and Diversity (SEEDS) 11th annual leadership meeting. An award-winning program of the Ecological Society of America (ESA), SEEDS focuses on students at the undergraduate level, with the mission to diversify and advance the ecology profession by stimulating and nurturing the interests of underrepresented students to participate and lead in the field of ecology.
