Emerald ash borer
The emerald ash borer? What is this bug? It is a beetle, a flying insect that is particularly fond of ash trees. The problem is that it manages to commit devastating acts to ash trees. The larva attacks the interior of this species by digging serpentine galleries. The insect takes care of the foliage.
The intruder entered North America in 2002, arriving from Asia. Canada and Quebec are not spared. The insect can be found in everything made of ash wood. The emerald ash borer can travel in raw wood or be camouflaged in wooden products such as crates or pallets, for example.
The effects of the emerald ash borer on the trees
The invertebrate attack usually ends in about five years, with the death of the tree. But the duration can be less if the tree species is young.
The strange insect starts its attack from the head of the tree and works its way down towards the base. The larval actions inside the tree block the sap, depriving the large plant of nourishment. The visible signs are early yellowing or balding of leaves, and removal of bark.
