Asian Longhorned Beetle

Quarantine and Regulatory Aspects

To prevent further infestations, the New York State Department of Agriculture and Markets (NYSDAM) has established quarantine areas in New York City and Long Island in which the movement of ALB regulated materials is restricted.  Currently, 135 square miles of New York City and Long Island are under quarantine.

1NYCRR Part 139, Control of the Asian Longhorned Beetle, contains the regulations relating to activities involving the handling of ALB host material.  This regulated material may not be removed from Quarantine areas unless accompanied by a Limited Permit authorizing such movement.  Anyone handling ALB regulated material who wishes to obtain a NYSDAM Compliance Agreement, enabling the movement of wood for purposes of disposal, may do so by contacting NYSDAM.

For questions concerning these regulations and for Compliance Training, please contact Frank Buccello at (718) 820-1329, or Michael Dorgan at (631) 598-5943.

On May 14, 2013 after a 14 year cooperative effort, Asian Longhorned Beetle (ALB) was declared eradicated from the New York City boroughs of Manhattan and Staten Island. Using a multi-faceted approach of survey, treatment, and control, program staff contained the spread of this destructive pest and effectively eliminated it from Manhattan and Staten Island. These two areas follow Islip, Long Island which was declared "ALB free" in September of 2011.The New York ALB Program continues to move towards total eradication of Asian Longhorned Beetle from New York. Two areas remain; Brooklyn/Queens and Central Long Island.

2012 marked the second consecutive year in Asian Longhorned Beetle Program history that no infested trees were detected or removed.

Delimiting Survey and Detection Response

As an ongoing response to detection of Asian Longhorned Beetle in New York, the areas under quarantine are surveyed. All properties must be accessed within the quarantine area and any host trees inspected to complete a cycle. The survey protocols require that three negative cycles must occur before an area can be considered free from infestation. In 2012, both ground and climbing staff visited a total of 51,136 properties and inspected 122,319 trees.

In order to ensure no other areas of New York are harboring infestation, inspectors work outside the quarantine boundaries on a regular basis, to target and inspect businesses and areas considered at high risk for infestation. The inspectors visited campgrounds, importers, freight rail lines and industrial parks. They accessed 178 establishments and surveyed 2,074 host trees with no new introductions detected.

Background and Biology

The Asian longhorned beetle (ALB) is a dangerous pest of hardwood trees.  Native to China, Japan, and Korea, the insect likely was transported into North America in solid wood packing materials used for international shipping.  The first North American infestation was discovered in Brooklyn, NY in 1996, and infestations have subsequently been found in Long Island, New Jersey, Illinois, Massachusetts, Ohio, and Ontario, Canada.  In these areas, tens of thousands of trees have been cut down to prevent the spread of ALB.

Adult ALB have a shiny, jet black body with distinctive white spots.  They are approximately 1 to 1 ½ inches in length, with very long black and white banded antennae.  ALB prefers to attack maple (Acer) species, including boxelder, but also can be found in other hosts such as willow, elm, birch, poplar, and horsechestnut.  Larvae of ALB tunnel under the bark of infested trees, resulting in girdling and disruption of nutrient transport and ultimately the death of infested trees.  Adults chew their way out of trees, creating tell-tale signs of infestation in the process, including round dime-sized emergence holes and a mixture of waste and tree material called frass.  Adults are active from July until October, and typically do not disperse far from trees from which they emerged.
