Emerald Ash Borer

What is the Emerald Ash Borer?

The emerald ash borer (Agrilus planipennis) is a non-native insect that poses an enormous threat to our urban and rural forests.  The emerald ash borer (EAB) kills ash trees by feeding under the bark and disrupting the flow of nutrients and water throughout the tree.

The beetle's identity was confirmed in Windsor, Ontario in July 2002.  Emerald ash borer has also been spotted in Amherstburg, Essex, LaSalle and Tecumseh -- all towns in southwestern Ontario.  The source of the infestation is unknown, although it is speculated that the emerald ash borer was introduced to Canada via wooden shipping crates.

The emerald ash borer attacks ash, walnut and elm trees in its native lands of China, Mongolia, Korea, Japan, Taiwan and the Russian Far East.  In Canada, only ash trees appear to be attacked and killed.  All 16 native ash species are probably susceptible to this insect.

 

A further detailed description of the emerald ash borer and its life cycle is available. View information on the Emerald Ash Borer on the Canadian Food Inspection Agency website or at the Ministry of Natural Resources website.
