July 15, 2016 - European Cherry Fruit Fly

On June 27, 2016, the presence of European cherry fruit fly (Rhagoletis cerasi) was confirmed in an urban park in Mississauga, Ontario. This marks the first confirmed detection of this potentially destructive invasive insect in North America. 

The adult European cherry fruit fly is predominantly black in colour, with transparent wings striped with dark crossbands. The scutellum of the thorax is yellow and lacks a black basal mark (Photo: Coutlin R. / OPIE).

  • The pest poses no threat to human health
  • To date, the pest has not been reported in association with cherry production in Ontario

Attacked cherry fruits are pitted with oviposition puncture marks and exit holes. The tissue surrounding these punctures will appear soft and brownish (Photo: Coutlin R. / OPIE).

Map the Invasive Host

In addition to Prunus spp. (cherries), the European cherry fruit fly attacks Lonicera spp. (honeysuckle). Some species of honeysuckle are invasive to Ontario, and can be found throughout the province. Help map the distribution of this invasive shrub on EDDMapS Ontario – this can inform experts of areas that may be at high risk for European cherry fruit fly invasion!
