How did the emerald ash borer arrive in Canada?

Emerald Ash Borer was first discovered in North America in 2002. It is thought to have been shipped to Canada in untreated wooden packaging materials. The range of Emerald Ash Borer in Ontario is rapidly expanding through the movement of infested materials.

How did the emerald ash borer become invasive?

Scientists now estimate that EAB was introduced during the early 1990's from infested solid-wood packing materials such as pallets and crated used in international trade. The spread of EAB results from transport of infested ash nursery stock, logs, and firewood, as well as natural dispersal.

How did the emerald ash borer get to Iowa and the Midwest?

The beetle flies short distances on its own, but people have contributed to the spread of this pest by moving infested material, including firewood. EAB can unknowingly be transported beneath the bark of firewood.

When did the emerald ash borer arrive in North America?

Quick facts. The emerald ash borer likely arrived in North America on wood packaging materials in the early 1990s. First detected near Detroit, Michigan and Windsor, Ontario in 2002, the beetle has spread to more than 30 states and 5 provinces since then.

Where did the EAB come from?

Where did the emerald ash borer come from? The natural range of Agrilus planipennis, or the emerald ash borer, is eastern Russia, northern China, Japan, and Korea. Before June of 2002, it had never been found in North America.

Can emerald ash borers fly?

After emergence from a tree trunk; adult emerald ash borers typically fly within a ½ mile from their emergence tree to feed on the leaves of another ash tree and lay eggs. However, they can fly up to 10 miles, especially when ash trees are not available within their normal flying zone.

What insect is killing ash trees?

Emerald ash borer (Agrilus planipennis) is an exotic, invasive, wood-boring insect that infests and kills native North American ash trees, both in forests and landscape plantings.

When was EAB introduced?

Established populations of EAB were first detected in the United States and Canada in 2002 (Haack et al., 2002), and based on a dendrochronology study by Siegert et al. (2009), the original EAB introduction likely occurred in the early to mid-1990s in Michigan.

Do ash borers eat other trees?

Does the emerald ash borer affect other trees? In rare cases, EAB has been found on other trees, such as fringe trees, but EAB mostly feeds on ash trees. In its early stages, EAB tunnels into trees and feeds on the area just underneath tree bark. As adults, the pests eat ash tree leaves.

Where is the emerald ash borer in North America?

American EAB locations include Alabama, Arkansas, Colorado, Connecticut, Delaware, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Nebraska, New Hampshire, New Jersey, New York, North Carolina, South Carolina, South Dakota, Ohio, Oklahoma, ...

Where does the emerald ash borer occur in the US?

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.

What is being done to stop the emerald ash borer?

Homeowners can protect ash trees against EAB with the systemic insecticide imidacloprid, applied to the soil at the base of the tree. It is most effective when applied in spring but can also be applied in fall. It is less effective on trees over 50 inches in circumference. Follow label instructions carefully.

When did the emerald ash borer arrive in Canada?

The emerald ash borer is an invasive insect that was first discovered in Ontario in June 2002. The beetle likely crossed into Ontario at Windsor after establishing in the Detroit area, where it probably arrived in wood packaging or pallets.

Is the ash borer gone?

Eradication is no longer feasible for the emerald ash borer in North America. In January 2021, USDA APHIS terminated the domestic regulatory program it had implemented since 2003. At that time, 1,198 counties in 35 US states were released from the federal EAB regulation (EAB Manual 2020).

What killed the ash trees?

Ash trees are common in yards and along streets, but they are being decimated throughout the United States and parts of Canada by the ruthlessly-harmful pest called the Emerald Ash Borer (EAB).
