The Cranberry Tree

Another One Bites the Dust….

Emerald Ash Borer (EAB) has moved onto eastern Wisconsin was yesterday’s breaking news.  Vernon County borders MN and Iowa.  It sounds like this EAB has been in this new county over 5 years, but just discovered now.   It’s getting closer to our home state.  EAB can fly ½ mile away from the tree they emerge from.  However, EAB moves by humans…through moving firewood.

EAB is an invasive exotic species which normally occurs in Russia, China, Japan and Korea.  First found in 2002 in Michigan, the insect appears to come over from shipping lanes in the Great Lakes.  Now is in 10 states and 2 providences in 7 years.

When found in an area, quarantine lines are drawn and ash trees are proactively cut down.  The insect only attacks ash trees so if remove the host, stop the insect.

Here is a picture of the emerald ash borer and the galleries where the larvae eat away the water and nutrient carries tissues.
