Asian Longhorned Beetle (ALHB) - Latest Information

You can help....

  • If you find a beetle, or see signs of infestation, contact the CFIA’s toll-free line at 1-800-442-2342.
  • Do not move any regulated articles (including nursery stock, firewood, and fallen or pruned branches) from the infested area. This will reduce the risk of spreading the beetle.

October 14, 2005

The CFIA has detected a number of ALHB infested trees in the City of Vaughan in an area north of Highway 407, east of Islington Avenue, and in the City of Toronto in an area north of Finch Avenue, east of Islington Avenue. The infested trees were detected during the course of on-going surveys.

Approximately 2,000 host trees within 400 metres of the infested trees are required to be removed to effectively prevent the spread of the ALHB. All trees are within the Regulated Area, which was established in parts of Toronto and Vaughan in February 2004 to prevent the spread of the beetle. A total of approximately 10,000 trees have been identified for removal to date. A “Notice to Dispose” will be issued to affected property owners prior to tree removal.

Information continues to be collected by the CFIA and the Canadian Forest Service (CFS) as host trees are removed. All data collected will be studied and used to strengthen the ALHB Action Plan and ongoing eradication efforts, and the CFIA will continue to seek acceptable alternatives to tree removal. The removal and disposal of host trees is considered the most effective means of controlling the spread of the ALHB. At the present time, it is the only option for control available in Canada.

Compensation

The CFIA is offering compensation to property owners who replace trees ordered removed. Property owners who have received a Notice to Dispose on or before March 31, 2006 are eligible for compensation. To receive compensation, property owners must complete and submit an application form on or before December 31, 2007. The forms are available from the CFIA’s Toronto regional office at (416) 665-5055.

Compensation is provided on the basis of the direct cost of replacing a tree up to a maximum amount (i.e., purchase of a tree plus planting costs). The maximum amounts are $300 per tree ordered destroyed on private property, $150 per tree on public property and $40 per tree in woodlots. Replacement trees must be non-host (not susceptible to attack by the ALHB) to be eligible for compensation.

The CFIA needs the help, cooperation and support of the public, and is reminding the public that movement of firewood and regulated articles out of the Regulated Area in Toronto and Vaughan is prohibited under the Asian Long-Horned Beetle Infested Places Order.

August 11, 2005

Since April 2005, in the continued effort to eradicate the ALHB, CFIA inspection teams have detected a number of ALHB infested trees in three locations in the City of Vaughan and one location in the City of Toronto.

All host trees within 400 meters of the infested trees will be removed to prevent the spread of the ALHB.

Approximately 7,000 trees will be removed in August from residential, commercial and industrial properties, including a cemetery. The trees will be studied and the data collected will be used to strengthen the ALHB Action Plan.

The infested trees were located within the Regulated Area and as such, no additional regulatory restrictions will be imposed.

Public information sessions will be held in the communities affected by tree removal. Area residents and members of the general public will be invited to attend these sessions to learn more about the ALHB.

Intensive survey continues.

April 20, 2005

As part of the continued effort to eradicate the Asian Long-horned Beetle (ALHB) survey activity has been on-going since the pest was first discovered in September 2003. Early this year, CFIA inspection teams identified trees infested with the ALHB in an industrial and commercial area of Vaughan.

Two trees exhibited exit holes and egg-laying sites from late 2004. These trees, as well as all host trees within 400 metres of these trees were removed to prevent the spread of the ALHB. Approximately 1,000 trees were removed. No residential properties were affected.

The infested trees were located within the Regulated Area and as such, no additional regulatory restrictions will be imposed.

The CFIA continues to work with its partners on this program. Intensive surveying is ongoing.

The CFIA maintains and enforces restrictive measures for the movement of potentially infested wood items from areas where the beetle was found. On March 1, 2004, a regulated area was established in parts of Toronto and Vaughan in order to prevent the spread of the ALHB.

There are prohibitions or restrictions of movement on nursery stock, trees, leaves, logs, lumber, wood, wood chips and bark chips from certain deciduous trees identified as hosts of the ALHB, and firewood of all species. Unless authorized by the CFIA, their movement out of or through the regulated area is prohibited. This is necessary to prevent the spread of the ALHB throughout Toronto and the rest of Ontario and Canada. Any person who contravenes this order may be subject to a fine and/or be liable to prosecution.

December 9, 2004

Tree Removal and Surveys

Removal of all host trees within 400 metres of the ALHB infested tree has been completed. Approximately 100 trees were removed and destroyed in the on-going effort to eradicate the ALHB in Vaughan. No residential properties were affected by the removal of these trees.

The removal and destruction of host trees is considered the only effective option for eradicating this beetle. Surveys are continuing.

November 5, 2004

Surveys

Surveys have been on-going in Toronto and Vaughan since the completion of tree removal in March 2004. Survey within the Regulated Area has found nine trees with signs of infestation since August 2004. In total 19 trees have been removed and are being studied to provide further information on the ALHB infestation.

These trees have been determined to be 2003 infestation. One of these trees exhibited new exit holes and evidence of 2004 feeding damage and egg-laying activity. Consequently, all host trees within 400 metres of this infested tree will be removed to prevent the spread of the ALHB.

The area of this infestation is comprised of industrial, commercial and retail properties. No residential properties are affected by removal of these trees. Removal and destruction of host trees is considered the only effective option for eradicating the beetle. Surveys are continuing.

August 9, 2004

Surveys

Following the completion of tree removal at the end of March 2004, 10 additional infested trees have been removed in the zone of infestation. No exit holes were found, and the oviposition sites have been determined to be the previous year's infestation. Survey is on-going.

Sentinel Tree Study

  • The CFIA has installed sentinel trees to aid in the detection of any remaining ALHB within the Regulated Area.
  • With the permission of property owners, potted trees and traps have been placed in strategic locations throughout the Regulated Area. These locations are inspected on a continuous basis for signs of infestation.

Survey of Non-host Species in the Regulated Area

  • The CFIA is currently deploying inspectors in the Regulated Area to survey non-host trees. Non-host trees such as Linden, Ash, Oak, and fruit trees are being surveyed and tagged for inventory and data collection purposes. These surveys will be on-going for several years.

Compensation for Tree Replacement:

    December 18, 2003

    More than 175 hectares of the Toronto and Vaughan urban forest has been surveyed to-date, including individual public and private trees, ravines, and woodlots. Surveys have been conducted from the ground, by tree climbers and/or bucket truck teams.

    There are four levels of activities associated with the Asian Long-horned Beetle (ALHB) Survey and Eradication Plans:

    1. Survey: Crews are evaluating the characteristics of the pest population, as well as making tree identifications. This determines the ALHB dispersal and the impact on host tree material in the containment / controlled area. This information is being used to establish and confirm the ALHB Regulated Zone boundaries. Survey crews also follow up on 1-800 referral calls from the public.

    2. Tree Removal / Disposal: Crews are removing trees that have been identified and tagged by survey staff for removal due to ALHB infestation (to eliminate the ALHB from the area). Trees removed from public and private property that are suitable host trees, but are not infested, are chipped onsite. Trees that are infested are transported to a designated CFIA site for research assessment and disposal.

    3. Research: Evaluation of tree material for the purpose of collecting valuable scientific data to create a body of knowledge for planned activities, for example: to develop the eradication approach for the satellite areas, to support the current CFIA ALHB eradication activities, and to generate data for the international science community.

    4. Disposal: Crews responsible for chipping and tub grinding the ALHB infested tree material into safe, recyclable material.

    Tree Removal / Disposal and Research

    Three removal crews are currently working in the primary infested zone. The information that is currently being gathered will be utilized to determine the best, and most effective approach in dealing with parks, ravines, wood lots and satellite areas.


    November 17, 2003

    Approximately 96 hectares of ground and / or tree canopies have been surveyed by ground, ravine and tree climbing / bucket truck teams this week. On average, a total of 25 survey crew members have been in the field carrying out survey work.

    Cutting of trees on public property is to begin on November 20, 2003. Trees on private property will be scheduled for removal prior to the spring.

    Survey activities will continue at two levels - intensive and extensive. The survey teams plan to continue the intensive surveys in advance of tree removal and collect tree inventories (by tagging and photographing infested and host trees), especially within the core area of infestation or "epicenter" at Steeles Avenue. During tree removal, an extensive examination of the trees will be conducted after they are cut down to collect ALHB scientific data.

    The CFIA continues to work with other government departments and partners for a detailed examination of ravines in the area. None of the trees examined to date have shown evidence that the ALHB attack has spread into the ravine areas.


    October 8, 2003

    Approximately 900 hectares have been surveyed by ground crews and tree climbing teams per day. Survey crews completed the evaluation of the York University and 407 areas, where no positive identifications were discovered.

    The current delimitation survey area has expanded to 13x13 km (17,742 Hectares). This area extends 3-4 km beyond the confirmed positive identification sites. Survey crews will have completed 68% of this area by Monday, October 6, 2003.


    September 29, 2003

    An Asian Longhorned Beetle (ALHB) was discovered in Woodbridge, Ontario on September 4, 2003, by a member of the public. The sample was collected by the Canadian Food Inspection Agency (CFIA) and positively identified by the CFIA’s Centre of Plant Quarantine Pests on September 8, 2003.

    CFIA staff surveyed the area where the beetle was found and discovered trees that had been attacked by the ALHB. This is the first find of ALHB infesting trees in Canada. The beetle is native to Asia and was likely introduced into Canada through wood packaging used in shipping.

    While the insect will not infest homes or workplaces and presents no threat to public health, the beetle does pose a significant threat to Canada’s trees and forests. The ALHB has no natural controls in North America that would prevent its spread. The beetle prefers hardwood trees, especially maple and horsechestnut, and kills trees when their larvae feed within tree trunks and limbs, causing them to die.

    The CFIA is implementing an aggressive campaign to control and eradicate this unwanted pest with the full cooperation of the City of Vaughan, the City of Toronto and other federal, provincial and municipal partners. All material from infested or neighbouring host trees must be destroyed to eliminate the risk of ALHB spreading to uninfested trees.

    ALHB SURVEY UPDATE

    Tree surveys in the area have determined the central area of infestation to be in a primarily industrial area roughly bordered by Hwy. 407, Hwy. 400, Finch Ave. W., and Milvan Drive in Woodbridge and Toronto.

    As of September 29, 2003, survey crews have found satellite infestations in the Ansley Grove Road area of Woodbridge, Beechwood Cemetery, and in the Thistletown area of Toronto.

    Over 4000 hectares have been surveyed, as of September 29, 2003. Approximately 550 hectares are surveyed by ground crews and tree climbing teams per day. Approximately 60% of the 125 square kilometre survey zone has been completed to date. Please visit the survey map to see the survey area.

    YOU CAN HELP

    To reduce the risk of spreading the beetle, residents and hired landscape maintenance companies or property management companies are asked to not move any tree materials (including nursery stock, firewood, and fallen or pruned branches) from the infested area.

    Anyone who finds a beetle, or sees signs of infestation, should contact the CFIA’s toll-free line at 1-800-442-2342. Do not remove a beetle from the area.

    For more information about ALHB, including pictures of the insect and signs of infested trees, please visit the CFIA website at www.inspection.gc.ca.

    We will continue to provide updates as new information becomes available.
