Indiana Worries About Borer

The emerald ash borer, an Asian invasive insect, was recently discovered in Ohio and Michigan. This has forestry officials in Indiana concerned. Although no insect has been found in Indiana, Purdue University entomologists are monitoring the northwest part of the state.
"When you consider that we have 147 million ash trees in Indiana, this is bad news for Indiana homeowners as well as the recreational, timber, horticulture, and nursery and landscape industries in the state," said Jodie Ellis, a Purdue Extension entomologist.
The emerald ash borer larvae live under the tree's bark, where their feeding disrupts the flow of nutrients throughout the tree. In most cases, an infestation of emerald ash borer will kill affected trees within three years or less. The borer is believed to affect all species of ash.
Canada is actually turning back firewood brought in from the United States. One customs employee says,"Our priority has got to be to slow down this thing (ash borer) - long term, we are trying to find ways to battle it and prevent it."
