The apple maggot (Rhagoletis pomonella) has recently been found in several locations in the Lower Mainland and Vancouver Island areas of British Columbia. These are the only areas in British Columbia where the pest has been found, based on an annual survey throughout southern B.C. conducted by the Canadian Food Inspection Agency (CFIA). Every effort must be made to keep this serious pest from spreading to the interior of B.C.

Quarantine Regulations:

CFIA is exploring regulatory options to implement in consultation with the B.C. Ministry of Agriculture, stakeholders and industry groups.

To help prevent the spread of apple maggot to other parts of B.C., please contact the CFIA at 604-557-4500 if you are planning to move apples, apple trees or other host plants with soil, or nursery stock of apple, crabapple or hawthorn, out of the Fraser Valley. Soil under or adjacent to infested host trees may contain apple maggot pupae, thus any plants removed from the site with soil pose a risk of moving the apple maggot.

For more information on domestic movement and import regulations, please refer to the Canadian Food Inspection Agency policy directive D-00-07.
