How to stop Emerald Ash Borer?
They are an important part of the temperate forest ecosystem and are harvested for use. Targeting the larvae is instrumental in stop ping the spread of the Emerald Ash Borer, and the only known solution to stop them is the removal and destruction of all infected trees. This usually results in an entire neighborhood's treescape changing because Ash trees were popular decades ago in urban and suburban planning. In many places, this species alone was planted for miles. Now block after block loses shade and character in an effort to stem infestations.

The adults that emerge from the tree trunks leave a small, visible "D" shaped hole in the bark of the Ash tree. They proceed to feed off of the tree's foliage before mating several weeks later.
Why do ash trees die?
The death of the tree is caused by dehydration and starvation. The small tunnels block or destroy the xylem in the tree trunk which allows water to move up the tree. Ash trees that are infected and impaired will have seasons where only a few branch clusters grow leaves, while other parts are bare.

Where did the Emerald Ash Borer originate?
The Emerald Ash Borer (Agrilus planipennis or EAB) is responsible for the destruction of tens of millions of ash trees in 30 states. Native to Asia, it likely arrived in the United States hidden in wood packing materials. The first U.S. identification of Emerald Ash Borer was in southeastern Michigan in 2002.
How to control Emerald Ash Borer?
Emerald Ash Borer infestations can be managed in several ways. Preventing the spread of the pest through quarantine of ash nursery stock, firewood, and other wood products capable of harboring eggs and larvae may reduce long-distance spread. Previously the Animal Plant Health Inspection Service (APHIS) regulated movement of items that were likely to spread the species by quarantining areas where it was found. In a rule published in the Federal Register on the 15th of December 2020, APHIS changed its approach to managing EAB and dropped domestic quarantine regulations to focus on less invasive and more effective strategies.
How long do ash borers live?
In its introduced range within North America, the Emerald Ash Borer may take 1-2 years to complete its life cycle. Adults begin to emerge in May or June with peak emergence in mid-June to early July. Adults live between 3 and 6 weeks during which they seek mates on suitable host trees. Females produce an average of 40-70 eggs but may produce up to 200. These are deposited in cracks or crevices on the host tree. Approximately 2 weeks later these eggs hatch and larvae burrow into the vascular tissue of the tree. Larvae continue to feed through the fall and overwinter in chambers within the bark or outer sapwood. The cycle is completed the following spring when these larvae pupate and emerge as adults. Some larvae extend this life cycle and spend an additional summer feeding before emerging the next spring (as reviewed in Herms and McCullough 2014).
What is the color of beetles?
The following is from Parsons (2008). Adult beetles are typically bright metallic green dorsally with the elytra being duller and darker green.

Emerald Ash Borer is somewhat larger in size and more brightly metallic green than most other species in the genus Agrilusthat are present in North America with total lengths less than 10-13 mm. This is the only North American species in this genus that has a bright red dorsal surface of the abdomen when viewed with the wings and elytra spread. A small blunt, slightly notched, spine is present at the tip of the abdomen and the antennae are serrate or toothed after the fourth segment.
