The emerald ash borer (Agrilus planipennis) is a deceptively attractive metallic-green adult beetle with a red abdomen. … Scientists think that tiny parasitic wasps, which prey on emerald ash borers in their native range, hold the key to curbing this invasive species and returning ash trees to North American forests.
What trees do ash borers affect?
What types of trees does the emerald ash borer attack? In North America, ash trees are the only tree species to be attacked by EAB. Trees in woodlots, as well as landscaped areas, are affected. Larval galleries have been found in trees or branches measuring as little as 1-inch in diameter.

EAB was first found in Ohio in 2003. Since then, this insect has spread throughout Ohio and has killed millions of ash trees nationwide. EAB continues to be a threat in Ohio today, although populations of the pest are much lower than at the height of its initial invasion.
Is the emerald ash borer still a problem in Illinois?
The insect arrived in the U.S. in the 1990s, but wasn’t identified until the early 2000s. Since then, emerald ash borers have killed tens of millions of trees in 30 states, according to the USDA.

Are there ash trees in Asia?
Unlike North American ash, Asian ash species have lived along with EAB for millennia and have evolved an unknown set of genes — a metaphorical playbook — which allows them to resist the beetle’s attacks.
Do ash trees have flowers?
Most ash trees are dioecious – that is, the tree has either all male flowers (staminate) or all female (pistillate) flowers.

Do emerald ash borers live in dead wood?
Do emerald ash borers live in dead wood? If borers were in the tree when you had it removed, there’s a good chance they’re still there. So, assume EAB is in dead wood. Don’t transport it farther than 50 miles from where it was cut because the emerald ash borers could infest a whole new area.
What attracts the emerald ash borer?
EAB has also been found to be attracted to volatiles from ash leaves and bark, to the colors green and purple, and to open grown trees in sunny locations. Developing improved traps and lures for early detection remains a critical need for regulatory programs and for managers to implement rapid control measures.
What happens to the emerald ash borer when all the ash trees are dead?
