French common name: Agrile du frêne
Scientific name: Agrilus planipennis Fairmaire
The emerald ash borer (EAB) is an invasive wood-boring beetle, native to parts of Asia. It was detected in the Detroit, Michigan and Windsor, Ontario areas in 2002, but likely existed undetected in North America since the 1990's. Experts believe the EAB was introduced to Detroit hidden inside wooden packaging materials or shipping crates. Since its arrival, the EAB has been rapidly spreading across North America, having devastating effects on the ash tree population, killing up to 99% of ash trees in its path. The EAB continues to spread in all directions across North America where ash trees are present.
