1
The Emerald Ash Borer
  • Agrilus planipennis (Coleoptera: Buprestidae)
  • Kyle Meister, MSU Extension, Ingham County
2
What is the Emerald Ash Borer?
  • An exotic wood-boring beetle, native to east Asia
  • Known to feed only on Ash trees (Fraxinus spp.) in North America
3
How did it get here?
  • Most likely through un-kilned or untreated shipping materials from east Asia that arrived at a port in the Detroit area
4
How does it harm Ash trees?
  • Just like us, plants have vascular systems
  • EAB larvae feed on the cambium of trees, an area between the bark and wood that contains most vascular tissue (phloem and xylem).
  • EAB larval feeding disrupts the flow of food, water and nutrients within the tree, eventually killing it.

6
How do I know if a tree has EAB?
  • Early detection is extremely difficult!
  • Canopy dieback
  • Vertical splitting in bark
  • Sprouting/ Suckering
  • Woodpecker holes
  • D-shaped exit holes
  • When bark is removed, many larval tunnels can be seen

Infested trees
8
What is being done to stop EAB?
  • Research: Biology and Behavior, genetics, pesticides, trapping, natural enemies, geographic distribution, geographic information systems (GIS)
  • Communication with other states → preparation
9
What can I do?
  • SAVE YOUR ASH!
  • DON’T MOVE FIREWOOD!!!
  • Help to restore and diversify the urban forest: replace ash with many types of native trees and recommended cultivars in order to avoid or hinder future pest outbreaks.
