Asian Long Horn Beetle

Asian Long Horned Beetle

While native to north eastern Asia, the destructive Long Horn Beetle is a serious insect threat to many species of trees in Ontario including birch, elms, hackberry, maple, mountain ash, poplar, aspen and willow trees. The larvae are actually more destructive then the adult beetles since it is the larvae that tunnel through the trees wood and disrupt it's vascular systems leading fungal growth. This causes structural weakness to the tree, causes limbs to fall, and ultimately may result in death.

These tree pests prefer a smooth bark upper crown of a young and healthy tree, however they will attack older tree stems and even the exposed surface roots of older trees. Most of the time infected trees will die within just a short period of time. The most vulnerable trees to a infestation by the Asian Long Horned Beetle are birch, maple, poplar, elm, horse chestnut, hackberry, willow and mountain ash trees.

Detecting An Asian Long Horned Beetle Infestation:

The mature Asian Long Horned Beetle will begin to emerge during early summer in the months of May to later October and their peak activity is in July. Bored exit holes from 15 to 20 mm in diameter and larger are basic signs of your tree being infested. Tree sap will often be oozing from these holes and you'll sometimes see course sawdust on the lower limbs and/or the ground below the holes. In addition dying or dead limbs and yellowed leaves are a sign as well.

Asian Long Horned Beetle Treatment Options:

Prompt treatment and/or total eradication of the infection is necessary. There are several options available such as quarantine, insecticide, and complete tree removal.

 

Oak Wilt

Oak Wilt Disease

Oak Wilt is a serious disease of oak tree species, The disease is caused by a fungal infection of the tree that attacks the water conducting system of the tree and causes the branches to wilt and die. The disease infects oak trees through roots that are grafted between diseased and healthy trees and moves very rapidly. Oak Wilt can also be spread by bark and sap eating insects attracted to the open wounds on oak trees throughout the spring and summer months.

Detecting Disease:

The signs of Oak Wilt disease are a somewhat different between red and white oak's.

  • Red oak:

    Entire crown death. The leaves will turn yellow to brown from the leave tips to the margins. Total leaf drop within one year of oak wilt infestation. Unfortunately the majority of infected oak trees will die rapidly within a years time.

  • White oak:

    Localized dying of one or more limbs. The trees leaves will look like they have been soaked in water, are usually a dark green to taninsh colour, and will often remain hanging on dead limbs. While complete tree death in white oaks due to the disease is rare, it will happen on occasion and usually within just a few years.

  • Treatment Options:

    As with everything, early detection of the Oak Wilt disease is the most vital step in the prevention of the the spread of disease. If Oak Wilt infection is detected within your tree, several options are available which include digging of a trench between the infected tree and neighboring tree species that are vulnerable to infection with the goal of preventing any root transmission. Infected oak trees should not be cut down immediately, or the disease may potentially migrate to the trees roots system, and may increase the possibility of root transmission. A professional tree removal is really the only way to go if tree removal is necessary to prevent the infection of other trees.
