D-17-03: Phytosanitary requirements to prevent the spread of Rhagoletis cerasi L. (European cherry fruit fly) within Canada

Effective date: June 1, 2017

This directive describes domestic phytosanitary requirements to prevent the spread of Rhagoletis cerasi L. (European cherry fruit fly) within Canada. Fresh cherry fruit (Prunus cerasus, P. avium, P. mahaleb and P. serotina) produced in Ontario are prohibited movement to British Columbia and must be certified free of R. cerasi prior to being moved domestically to other provinces of Canada.

3.0 Introduction

In 2016, Rhagoletis cerasi L. (European cherry fruit fly), a regulated pest to Canada, was detected for the first time in Canada. This insect has been found in association with invasive Lonicera spp. in southern Ontario. Rhagoletis cerasi has not been detected in other provinces or in association with commercial cherry production anywhere in Canada.

Rhagoletis cerasi is a serious pest of cherry production in Europe. Damage is caused by larval feeding in the fruit pulp. Fresh fruit from host plants produced in areas where this pest occurs is a potential pathway for this pest.

Due to sensitivity to spring frosts and summer rains, sweet cherries (P. avium) can only be grown in a few locations in Canada. More than 90% of Canada's commercial fresh, sweet cherry production is in the southern-interior of British Columbia. Most of the remaining sweet cherry orchards are located in southern Ontario, where fresh cherries are grown for local consumption. Southern Ontario is the main production area for sour cherries (P. cerasus) in Canada. Sour cherry fruit is generally processed locally and sold as frozen product.

4.0 Scope

4.1 Regulated pest

Rhagoletis cerasi L.; European cherry fruit fly

4.2 Regulated articles

Fresh cherry fruit, including sweet cherries (Prunus avium), sour cherries (P. cerasus), mahaleb cherries (P. mahaleb) and black cherries (P. serotina) produced in a regulated area.

4.3 Exempted articles

  • Processed cherry fruit (frozen, canned, dried or processed in another way that mitigates pest risk)
  • Prunus cerasus, P. avium, P. mahaleb and P. serotina nursery stock

4.4 Regulated areas

Province of Ontario, Canada

5.0 Movement of regulated articles

5.1 To British Columbia


5.2 To provinces other than British Columbia

Regulated articles may only be moved to provinces other than British Columbia if they were produced in commercial orchards that applied control measures for fruit flies. The Canadian Food Inspection Agency (CFIA) will issue a Movement Certificate based on verifying that appropriate control measures were applied to control fruit flies and based on inspecting the fruit in the consignment and finding it free of cherry fruit flies (Rhagoletis spp.).

A CFIA Movement Certificate which includes the following statement is required:

"The fruit in this consignment was produced in a commercial orchard that applied control measures for fruit flies and was inspected and found free from Rhagoletis cerasi (European cherry fruit fly)."

6.0 Non-compliance

Fresh cherry fruit originating from Ontario is subject to inspection by the CFIA at destination. Consignments that are not covered by a Movement Certificate, or that are found to be infested with R. cerasi, or that are otherwise non-compliant may be returned to Ontario or destroyed. Infested shipments may be ordered treated to prevent the spread of pests prior to disposal. The person in possession, care or control of the shipment is responsible for all costs relating to treatment, disposal, removal, or re-routing, including costs incurred by the CFIA to monitor the action taken.
