How far has the emerald ash borer spread?

How is this pest spread? We know EAB adults can fly at least 1/2 mile from the ash tree where they emerge.

How fast does emerald ash borer reproduce?

These are active, sun-loving beetles, and after emergence they start mating after about one week and laying eggs in about three weeks.

How many eggs do Emerald ash borers lay at a time?

An “average” female may lay from 60 to 100 eggs during her lifespan, placing the eggs singly in bark crevices or under bark flaps on the trunk or branches (some long-lived females may lay more than 200 eggs).

How effective are emerald ash borer treatments?

When applied correctly, EAB treatment is 85 to 95 percent effective. EAB treatment works to save trees in your yards and your city. For example, when EAB was detected in Naperville, IL, they treated their trees. Three years later, more than 90 percent of the treated ash trees show no signs of infestation.

Is emerald ash borer under control?

The emerald ash borer (Agrilus planipennis) is a deceptively attractive metallic-green adult beetle with a red abdomen. In 2021 the U.S. Department of Agriculture stopped regulating the movement of ash trees and wood products in infested areas because the beetles spread rapidly despite quarantine efforts.

Can a tree recover from emerald ash borer?

EAB usually requires a minimum of a few years to kill an otherwise healthy tree. Infested trees can be successfully treated, even those with a fair amount of canopy decline. Beyond about 50 percent decline, however, recovery is less likely.

Where is an emerald ash borer most likely to lay eggs?

Found: When newly infesting a tree, EAB tends to lay eggs up in the crown of ash trees, in places where the bark is beginning to furrow. The eggs may be laid on the surface of the bark, in bark cracks and crevices or just under the outer bark of ash trees.

Why are emerald ash borers bad?

Since the discovery of emerald ash borers in the U.S. in 2002, its larvae has destroyed tens of millions of ash trees. The exotic beetle, whose larvae nibble on the inside of ash trees’ bark, can cause extensive damage to the way ash trees transport water and nutrients.

How much does it cost to treat a tree for emerald ash borer?

An average cost of treatment is approximately $11.00 per DBH. Dose rate of formulation and cost are determined by your tree’s diameter at breast height (DBH). Starting at 4½’ up from the base of the tree, measure the circumference of the tree’s trunk in inches with a measuring tape.

What is the scientific name for emerald ash borer?

Scientific name – Agrilus planipennis. Emerald ash borer (EAB) is an exotic beetle pest of ash trees (Fraxinus species). It is a member of the beetle family Buprestidae, and causes significant damage to the trees, including dieback and death.

Where are emerald ash borers found in Russia?

Forest Research scientists have visited Russia to study the pest there, and have co-written a scientific paper on the distribution, impact and rate of spread of emerald ash borer in the Moscow region.

Can a ash tree be imported from outside the EU?

Ash trees are prohibited from being imported from any country outside the European Union (EU), which includes all countries where emerald ash borer is present. Specific import requirements are in place for ash wood from countries where the pest is present.
