Emerald Ash Borer Attacks Michigan Trees

State Enacts Quarantine To Stop Spreading Of The Insect

Experts Say The Pest Has Been In Detroit For At Least Five Years.

Ash trees across the state and nation have an enemy that they cannot keep up with. The Emerald Ash Borer is a dark green,wood-boring beetle that is infested an estimated 15 million ash trees in many countries.

The exotic insect which is one-half-inch in length and one-sixteenth-inch wide was discovered in 2002, according to Michigan's Department of Agriculture.

Signs that the borer is present are usually undetectable until the tree begins to show symptoms of infestation. Typically upper portions of the tree begin to die and a large number of branches begin to shoot out below the dead parts.

Currently the state of Michigan has more then 700 million ash trees. A quarantine has been enacted to prevent future spreading of the Emerald Ash Borer.

A quarantine task force comprised of federal experts and state officials have developed a strategy to detect, contain and eradicate the insect.

Michigan State University's entomologist David Smitley says insecticide treatment is proving effective in saving healthy ash trees this fall.

Some keys components of the strategy include:
  • Providing sanitation and disposal options
  • Facilitating tree restoration/replacement whenever possible
  • Conducting ongoing surveys to ensure the pest is not spreading
  • Conducting research into the insect's biology
