LANSING — Severe winter weather may lead to the death of some invasive species, according to a recent study. In negative-10-degree weather, invasive species could freeze and die, the report from the USDA Forest Service and the Minnesota Department of Agriculture said. The report shows the effects of severe weather temperatures on the invasive emerald ash borer, an insect that feeds on ash and kills the tree. Regardless of the study’s findings and the bitter cold affecting Michigan this season, there is little hope for eradication of many of our invasive species, particularly the resilient emerald ash borer, said Deborah McCullough, a Michigan State University professor of entomology and forestry. “Given that temps have gotten really cold, and not for one night but for an extended period, there’s a tendency for a lot of people to hope for insect mortality,” McCullough said.
