The emerald ash borer is a beetle native to north-eastern Asia (Russia, Mongolia, northern China, Japan and Korea) which has made its way to North America and Eastern Europe. It has devastated the local ash tree population in the U.S and Canada, where it first came through wood shipments from China in the 1990’s.  The emerald ash borer was first found In Michigan and southeast Ontario in Essex County in 2002. Since the discovery in Michigan and southeast Ontario the emerald ash borer has also been found in Maryland, Ohio, Indiana, Virginia, Pennsylvania, and Illinois. Ash trees are essential for our economy and environment and they must be protected.

One of the main reasons why this topic is so important is because the emerald ash borer is wiping out the ash tree population, this is an issue because ash trees are very important to the environment and economy. In addition to this, ash trees are so crucial is because ash wood is greatly valued for its strength and elasticity, ash wood is also used for the production of baseball bats, bows, tool handles, hurling sticks, and other products that require strength, durability, and resilience. Green ash is planted widely as a landscape tree in urban areas and is a valuable native component for wetland areas. Moreover, why ash trees are so valuable is because ash foliage and seeds are fed upon by numerous animals as well as butterfly and moth caterpillars.  When ash trees are killed by the cause of the emerald ash borer, it is because of the adult beetles laying eggs on the bark of the tree. When the eggs hatch the larvae bore into the bark and feed on the transportation tissue of the tree. This process disrupts the movement of nutrients and water within the tree, which ultimately causing the tree to die.         

Effective methods of pest control include quarantines, removal of infested trees, insecticides and biological control. Quarantines are put in place when infestation occurs, and ash firewood and live ash plants cannot be moved from a specified area without a permit stating that they have been inspected or treated. Tree removals are a good way of control as ash trees are removed and replaced with non-ash trees such as maple, oak or linden to reduce food sources for the ash borer. This also improves the biodiversity of the area. Insecticides with azadirachtin, imidacloprid, emamectin benzoate and dinotefuran can be used but not by some homeowners and only by licensed applicators, so it cannot be used by everyone. They are also not feasible for large forested areas outside of urban areas since the insecticide must be injected directly into each tree. Finally, biological control has been used in pilot projects to eradicate ash borers by using parasitoid insects. Four species imported from China have been approved by the USDA and Canada: Spathius agrili, Tetrastichus planipennisi, Oobius agrili, and Spathius galinae have been used for several years. We believe that tree removal and biological control are the most effective ways of pest control, and we would like the government of Canada and provinces where the ash borer has been found to invest more into programs that allow more widespread use of these methods. Investing into pest control programs also means investing in our economy and keeping our landscape healthy and thriving.
