Emerald ash borer
The emerald ash borer is a beetle that attacks, as its name suggests, ash trees. The damage it can cause in comparison to its size is beyond comprehension. The larvae are active inside the tree itself and bore galleries in the shape of coils. As for the insect, it emerges from the tree to fly to the branches and nibble on the leaves.
Unfortunately, the emerald ash borer is present in Quebec. The reason it is so destructive is that it has no predators here. How does the emerald ash borer travel? It does so on board transported trees, raw wood, crates, pallets, ash logs and more. This mode of transportation is also how the emerald ash borer came to us from its native location in Asia.
The effects of the emerald ash borer on trees
How long does a tree take to decay amongst the presence of the emerald ash borer? Five years maximum, but a young tree can take as little as a year to die.
It is by deprivation of food that the tree's existence is destroyed, as the tunnels of larvae block the circulation for the sap to nourish the tree.
