The emerald ash borer has killed millions of ash trees since it was first discovered in North America in 2002. This exotic pest from Asia arrived without its natural enemies. One of the means of biological control currently being tested to fight this invader has involved releasing parasitoid wasps known for their high levels of parasitism in their native range. This could help reduce the density of the pest’s population to acceptable levels, thereby protecting the ash trees. So where do we stand at the Canadian Forest Service with respect to this invader?
