CALGARY, Aug. 1 /CNW/ - It isn't much bigger than a grain of rice, but in
the numbers that are invading Alberta, the Mountain Pine Beetle is making a
meal of our vast forests. An estimated million and a half trees have been
affected in the province so far and the infestation is a serious threat to
23 billion dollars worth of Alberta timber.
Current control efforts receiving wide attention mostly involve
prescribed burns but Genome Alberta and its partners are looking much deeper
into the underlying problem. The TRIA project is looking at the interaction
between the tree, the beetle and the blue stain fungus (hence the name Tria
which is Latin for three). The fungus is introduced into the tree by the
beetle and ultimately does as much if not more damage to the tree than the
beetle itself. The genome for the fungus has not been sequenced and the joint
Alberta - BC team is at the forefront of this research.
Understanding the complex relationship between the 3 species can take us
beyond burning as a control strategy. Once we have a complete picture of the
interaction we can predict Mountain Pine Beetle growth, spread, and behavior
so that industry and policy makers can develop stronger forest management
strategies. It will also give us a more complete picture of why some trees can
fight off the infection effectively and how it may be able to 'jump' species.
The new sequence information can be used in the study of other
insect-tree-fungus pests including the Southern Pine Beetle making its way
into Ontario, and the Bark Beetle already prevalent in parts of the United
The Tria Project was highlighted by Genome Alberta at the BIO
International Convention in San Diego recently and has received international
recognition for its novel approach to the Mountain Pine Beetle epidemic. The
work is helping Canada maintain its status as a leader in forest health
research and is generating information that can be used by researchers around
ABOUT THE MOUNTAIN PINE BEETLE
- The MBP is a small, black beetle about the size of a grain of rice.
Over the past few years, mountain pine beetles have been expanding
east into Alberta from British Columbia. Once a beetle has found a
suitable tree in July or August it will live there for the remainder
of its life and lay eggs. The new generation of beetles will not
emerge from the tree for at least one year.
- The beetles attack and kill pine trees, usually mature one, aged 80
to 120 years. All species of pine including Lodgepole, Jack Pine,
Scots pine, and Ponderosa Pine are vulnerable. Pine can be
distinguished from other trees by their long needles attached to
branches in clusters of 2-5.
- Trees successfully attacked by the Mountain Pine Beetle usually die
within a year.
