Cold snap has its benefits

In The Region:

There is an upside to the plummeting temperatures in Ohio.  Some insect pests could be impacted by the sub-zero conditions.

Ohio State University entomologist Dan Herms says a study of the emerald ash borer, a species that destroys ash trees, shows they don’t like the extreme cold.

“When temperatures get below zero the insects started dying and for example when temp get down to minus ten about a third of them died in the study and when temperatures got to minus 20, 80 percent died.”

But Herms warns that cold temperatures in December may have acclimated many insects to an already colder than normal winter.

He says most insects and wild animals are well conditioned to the extremes of an Ohio winter.
