Apple maggot fly detected in British Columbia
The apple maggot is a primary pest of cultivated apples, especially in the northeastern United States and southeastern Canada.
Adults: The adult fly is about 4–5 mm, or slightly smaller than a house fly (6–7 mm). It is black in color, with white bands on the abdomen (four on the female and three on the male), and the wings are marked with four oblique black bands (Image 1).
Larvae: The larvae are white or yellowish tapered maggots slightly smaller than those of the house fly (Image 2).
