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, 137 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 (516) 315-9003.

Asian Longhorned Beetle Eradication

Highlights

On May 17th, 2017, through a cooperative effort, Asian Longhorned Beetle (ALB) was declared eradicated from the Eastern Queens portion of the New York City quarantined area. Using a multi-faceted approach of survey, treatment, and control, program staff contained the spread of this destructive pest and effectively eliminated it. This area follows eradication success in Manhattan, Staten Island and Islip, Long Island. The New York ALB Program continues to move towards total eradication of Asian Longhorned Beetle from New York. Two areas remain; Brooklyn/ Western Queens and Central Long Island. The Eastern Queens deregulation removes 26 square miles from the NYC ALB quarantine.

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 2017, both ground and climbing staff visited a total of 80,322 properties and inspected 117,120 trees.

  • Quality Assurance - To remain vigilant that all survey of properties and trees is accurate, QA is conducted on a random percentage of properties and trees. In 2017, a total of 12,122 properties had a QA check performed.

  • Level 3 Survey - 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, pallet companies and industrial parks. Inspectors also conducted biometric survey which include survey of random points in pre-determined grids. They accessed 56 establishments and completed 31 biometric grids. In all, 2,895 host trees were surveyed with no new introductions detected.

  • Tree Removal and Detection - 43 infested trees were found in 2017 and 56 trees were identified as high risk. All the infested and high-risk trees were removed. Since the first detection of ALB in Greenpoint, Brooklyn, a total of 7,083 infested and 16,655 high risk trees have been removed.

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 1½ 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.
