How do I get rid of longhorn beetles in my tree?
ALB larvae burrow deep into trees, where they feed and continue to grow until they re-emerge as adult beetles. Insecticides cannot reach them inside the tree. The only way to eliminate the pest is by removing and destroying the tree.
Why are longhorned beetle invasive?
Asian longhorned beetle (ALB) larvae bore through wood of a wide variety of hardwood species, most notibly maples, elm, horsechestnut, willow, sycamore and birch. ALB boring phsycially weakens the trees and disrupts sap flow. Branches with boring damage are more likely to break off, creating a public saftey hazard.
How do you control ALB?
Currently the only effective means to eliminate ALB is to remove infested trees and destroy them by chipping or burning. To prevent further spread of the insect, quarantines are established to avoid transporting infested trees and branches from the area.

Where are Asian longhorned beetles found?
In 1992 the Asian longhorned beetle was first detected at ports of entry on the east coasts of both the United States and Canada, but it was exterminated before it could escape into the surrounding habitats. The first established population outside Asia was found in New York City in 1996. Subsequent populations have been reported in New Jersey, Illinois, Ohio, and Massachusetts, though the infestations in both Illinois and New Jersey have since been eradicated. Established populations have also been reported in Japan, Austria, France, Germany, and Italy. Transport of the Asian longhorned beetle to North America, Europe, and Japan occurred primarily in solid-wood packing materials (e.g., pallets and packing crates) containing developing larvae or pupae. In rare instances the beetle has been found in shipments of live plants.

Do Asian longhorned beetles have pupal stages?
The Asian longhorned beetle’s life cycle mostly occurs under the host tree’s bark, so homeowners will not see the egg, larva, or pupal stage.

The tree can leak copious amounts of sap. When the tiny larvae hatch, they chew their way into the tree and begin working just below the bark in the cambium layer. As they grow larger, they work their way deeper into the heartwood of the tree.

Taxonomy and description
Common names for A. glabripennis in Asia are the starry sky beetle, basicosta white-spotted longicorn beetle, or smooth shoulder-longicorn, and it is called the Asian long-horned beetle (ALB) in North America.
Adults are very large insects with bodies ranging from 1.7 to 3.9 cm (0.67 to 1.54 in) in length and antennae which can be as long as 4 cm (1.6 in) or 1.5–2 times longer than the body of the insect…
Range, habitat, and hosts
Asian long-horned beetle is native to eastern Asia, primarily in eastern China and Korea. Japan is often erroneously included in its native range. It is invasive outside its native range.
In its native range, A. glabripennis primarily infests plants like maple, poplar, willow, and elm trees. In the United States, A. glabripennis has completed dev…
Life cycles
Adult females lay 45–62 eggs in their lifetime by chewing a small pit through the bark of the host tree to the cambium and lay one 5–7 mm (0.20–0.28 in) long egg underneath the bark in each pit. Eggs hatch in 13–54 days depending on temperature. Eggs that have not developed enough, such as those laid in late summer or early fall, will overwinter and hatch the following season.
As an invasive species
Due to high tree mortality caused by larval feeding outside its native range, A. glabripennis can change both forest and urban ecosystems. In the United States, it can potentially destroy 30.3% of urban trees and cause $669 billion in economic loss. Early detection is used to manage infestations before they can spread.
