The emerald ash borer has been destroying ash trees in Michigan, Ohio,
Illinois, Maryland, and Ontario – and the bug is spreading. Now,
agricultural officials in Michigan are developing an early warning
system. By detecting the insects early, they hope to slow or even
prevent its spread. The Great Lakes Radio Consortium’s Tracy Samilton
reports:
Forestry agents will be designating a number of so-called trap trees in
every township in Michigan. The ash trees will act as sentinels. A
strip of bark will be removed from the trees, which stresses them and
makes them attractive to insects. A sticky substance called tanglefoot
will then be applied to the trees to catch the borers. Kara Bouchay is
with the Michigan Department of Natural Resources.
“Part of the struggle with having a borer that you can’t see most of
time because it’s underneath the bark, is when it’s in a low level
population, it basically flies under the radar. So the trap tree is a
way to bring it to a single location to detect it.”
If borers are found on a tree, all ash trees within a half-mile will be
destroyed to contain its spread. Bouchay says if the early detection
system proves itself, it will likely be implemented in other states as
well.
