Deadlier than Dutch Elm: U.S. Trees Stricken by a Plague of Ash Borers

By ANITA HAMILTON Wednesday, May 25, 2011

A voracious beetle known as the Emerald Ash Borer, first discovered in Detroit in 2002, has been gradually spreading, leaving a trail of destruction in its wake. The infestation has already killed some 60 million ash trees in fifteen states as far east as New York, and as far south as Tennessee. The toll of dead trees will likely surpass those felled Dutch Elm disease by the end of this year. “It is now the most destructive forest insect ever to invade North America,” says Deb McCullough, an entomologist at Michigan State University.

Ash borer season is in full-swing — the beetles mate and lay eggs in May and June. The bug is native to China and likely migrated stateside burrowed inside wooden shipping pallets. It has few predators in the U.S., which is one of the reasons the rate of the outbreak is unprecedented. But it is also very stealthy, because its larvae, which feed on nutrients just below the bark that keep the tree alive, are usually not visible until the tree is already in the ICU. (The mature beetles merely munch on leaves.) There are an estimated 8 billion ash trees in the United States. “It’s causing complete mortality of ash trees,” says researcher Dan Herms of Ohio State University, who notes that none of the 16 species of ash in the U.S. is resistant to the pest.
