Emerald Ash Borer
Emerald ash borer has been found in Champaign, IL along Market Street, just south of Interstate 74. This is the second infestation known in Champaign County with it being found in Rantoul a couple of years ago.

The infested tree in which it was found is almost completely dead with only live suckers at the base and a few live water sprouts. This indicates that the borer has been present for at least six years and probably eight to ten years in the tree. Surveys of nearby trees have not been completed.
Emerald ash borer adults continue to be present in all of the infested areas of the state and will persist for the next few weeks. Although each adult lives only two to three weeks, emergence over several weeks results in adult beetle presence for about six weeks. (Phil Nixon)
