Emerald Ash Borer
A small bug, not at all friendly, entered North America in 2002: the emerald ash borer. This half-inch flying insect attacks ash trees. That's why it's called EAB.
This insect arrived from Asia as a stowaway in pallets or transport crates made of ash. Since then, it has been visiting all of Canada in the same manner, or hiding in firewood being transported between different regions.
This unfortunate visitor has joined the ranks of our Quebec insect fauna. He is part of the family tree of beetles. You will recognize him by the green and iridescent color of his body. Its larva is white, and its favorite activity is the digging of galleries in coils. Having reached its adult shape and size, the insect emerges from the tree and then prefers to eat the leaves. The EAB is enormously devastating!
Its impacts on ash tree
As you may have guessed, it's an insect pest. Its destructive capacity is due to the fact that it has no natural predators in North America. So don't get rid of it. As if that wasn't enough, it operates on the sly and carries out its ravages for 1 to 5 years. Usually, the attacked tree dies and must be felled.
