Does Emerald Ash Borer Affect Mountain Ash?

The emerald ash borer (EAB), an invasive insect from Asia, has caused widespread destruction to ash trees in North America. One common question that arises is whether the emerald ash borer affects mountain ash trees. Mountain ash, also known as Sorbus aucuparia, is a species of tree that is often confused with ash trees due to their similar appearance. In this article, we will explore the relationship between the emerald ash borer and mountain ash trees.

Understanding the Emerald Ash Borer

The emerald ash borer, scientifically known as Agrilus planipennis, is a small, metallic green beetle that feeds on the bark of ash trees. It was first discovered in the United States in 2002 and has since spread to several states. The EAB lays its eggs on the bark of ash trees, and when the larvae hatch, they bore into the tree to feed on the phloem, which is the tissue responsible for transporting nutrients and water. This feeding disrupts the tree’s ability to transport resources, leading to decline and eventual death.

Mountain Ash and the Emerald Ash Borer

Mountain ash trees are not directly affected by the emerald ash borer. While they share some physical similarities with ash trees, their biological makeup is different. Mountain ash trees are resistant to the EAB because they lack the specific characteristics that make ash trees susceptible to the beetle. The emerald ash borer cannot survive on mountain ash trees, and the larvae cannot bore into the bark to feed.

Impact on Ecosystems

Although mountain ash trees are not affected by the emerald ash borer, the decline of ash trees has had a significant impact on ecosystems. Ash trees are a crucial component of many forests, providing habitat for a variety of wildlife species. The loss of ash trees has led to a decline in these species, which can have cascading effects on the entire ecosystem.

Preventing the Spread of the Emerald Ash Borer

To protect mountain ash trees and other non-host trees, it is essential to prevent the spread of the emerald ash borer. This can be achieved by following these steps:

1. Do not transport firewood or other wood products from infested areas.
2. Monitor ash trees for signs of infestation, such as D-shaped exit holes or sawdust-like frass.
3. Report any suspected EAB infestations to local authorities.

Conclusion

In conclusion, the emerald ash borer does not affect mountain ash trees. While the EAB has caused significant damage to ash trees, mountain ash trees remain unaffected. It is crucial to continue efforts to prevent the spread of the emerald ash borer to protect non-host trees and maintain healthy ecosystems.
