ST. PAUL, Minn. – Come the first of the year, a new pest quarantine will be put in place to protect Minnesota’s pine forests. The Minnesota Department of Agriculture (MDA) will implement an exterior state quarantine for the mountain pine beetle on January 1, 2015. This quarantine is designed to stop the movement into Minnesota of any wood potentially infested with mountain pine beetle.
This insect, which is native to the western United States and Canada, spends most of its life in the area of a pine tree between the bark and the wood. The adult beetles can release a pheromone, or natural scent, to attract other beetles and eventually they may overwhelm the health of entire stands of pines to the extent they all die off. This makes the mountain pine beetle one of the most damaging forest insects in North America.
Recently, these beetles and their larva have been found by MDA in wood brought into Minnesota. This quarantine will reduce the risk of the human-aided movement of the insect from happening again.
