Asian Longhorned Beetle (ALB) - Anoplophora glabripennis
On September 13, 1996, the Systematic Entomology Laboratory of the Agricultural Research Service confirmed a specimen sent to them for identification as A. glabripennis. This pest was collected on maple and horse chestnut trees by the New York City Parks and Recreation Department at Green Point in northern Brooklyn. It was initially identified by E. Richard Hoebeke of Cornell University. The Longhorned beetle is a pest found in China, Japan and Korea. This was the first detection of this pest in the United States.
The early stages of larvae of this beetle feed between the xylem and the phloem, and the later stages feed only on the xylem, inhibiting the tree's vascular system. It is most destructive when larvae cross perpendicular to the flow, thereby cutting off many vascular paths. Larvae can cut off the flow from vasular tissue and essentially girdle the tree. Adults emerge through three-quarter-inch holes in the bark. Recorded in the literature are the following hardwood hosts in Asia: Ulmus parvifolia (elm), Salix babylonica (willow), and Populus species (poplar). Hosts found in Brooklyn include Aesculus (horsechesnut) and Acer species (Norway, sugar and silver maples).
