Michigan biological control facility produces wasps for battle against Emerald Ash Borer

Great Lake Echo:

Experts used to say the number of ash trees lost in Michigan was tens of millions.

Now they say hundreds of millions, according to Deb McCullough, a professor in Michigan State University’s entomology and forestry departments. Still, there’s hope for the ash’s survival.

“In a nutshell, what I found is that [ash] seems to be holding on quite well,” said Dan Kashian, who studies ash tree regeneration.

The mortality varies among species, but now the devastation has become an international epidemic, McCullough said. While some patches are worse than others, it’s hard to find a lot of live ash trees in Lower Michigan and much of the eastern and central Upper Peninsula.

The culprit is the emerald ash borer, Agrilus planipennis Fairmaire, an exotic Asian beetle discovered in southeastern Michigan near Detroit in the summer of 2002. Adult beetles are metallic green and about 1/2-inch long. They hitched rides on ship and plane cargo originating from Asia and movint to Detroit.
