MSU researcher updates fight against ash borer

Oct 15, 2013

MSU researcher Deborah McCullough says the emerald ash borer might have arrived in Michigan as early as the 1980s.

The emerald ash borer has killed acres of ash trees across Michigan since 2002.  However, new research suggest the invasive beetle from Asia may have arrived in Michigan even earlier.

Deborah McCullough has a joint appointment in Entomology and Forestry at Michigan State University. She says the emerald ash borer was probably introduced from China, in solid wood packing materials used in containerized shipping.
