Asian Longhorned Beetle Alert
The Asian Longhorned Beetle (ALB)(Anoplophora glabripennis) is an invasive beetle believed to have arrived in New York from its native China via untreated packing crates and wooden pallets. Infestations have been discovered in Brooklyn, Queens, Manhattan, and Staten Island.
Tunneling by ALB larvae damages the vascular system of the tree. Repeated attacks lead to dieback of the tree crown, and, eventually, death of the tree. The beetle presents a serious threat to the trees of New York City and has also infested parts of Long Island, Chicago, Ohio, Massachusetts, and New Jersey.
The beetles are known to attack maple, horsechestnut, elm, willow, birch, poplar, and ash trees. Currently the only effective means to control the beetle is to remove infested trees and destroy them by chipping or burning. To prevent further spread of the insect, quarantine zones have been established to avoid transporting wood from the infested areas.
Early detection of infestations and rapid tree removal are crucial to the successful eradication of the beetle.
On May 14, 2013, the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (USDA-APHIS) announced that the boroughs of Manhattan and Staten Island were free from ALB. This announcement reduced the quarantined areas of New York from 135 to 109 square miles. Read the USDA press release about this success!
