Map Showing Where Emerald Ash Borer Has Been Identified (March 1st, 2013)
Adult Emerald Ash Borer Emerald Ash Borer Tree Trunk Damage
Emerald Ash Borer was found for the first time in Wisconsin in August, 2008 near the community of Newburg, along the northern Ozaukee and Washington County line.
In April, 2009, EAB was found in western Wisconsin, in the small town of Victory in Vernon County, alonside the Mississippi River.
In July, adult beetles were caught on survey traps located in Crawford and Brown counties.
In August, the Milwaukee County community of Franklin became the site of the latest confirmed presence of EAB when city officials alerted program staff to declining ash trees.
The damage of this insect rivals that of Chestnut blight and Dutch Elm Disease. To put its damage in perspective:
The beetle kills trees because the feeding larvae damage both the phloem (responsible for nutrient transport throughout the tree) and xylem (responsible for take-up of water and nutrients) tissues of the tree. The beetle effectively girdles the tree and starves it.
Losses are estimated in the tens of millions of dollars. There is a high probability that all American ash trees will be destroyed in our lifetime.
A pilot study is being undertaken in Michigan to determine if three different parasitic wasps can deter the emerald ash borer. These tiny stingless wasps can sense beetles underneath the bark and then lay their eggs in the larvae or egg, thus killing them. There have been doubts as to whether this biological control program will work due to the rapid progression of the beetle and death of the ash trees.
