Rhagoletis cerasi (the cherry fruit fly or European cherry fruit fly) is a species of fruit fly in the family Tephritidae.

Distribution

This species is widespread in most of Europe, except British Islands, in western Siberia to Caucasus, in Kazakhstan, Central Asia and Altai.[2] It was first detected in North America in 2016.[3]

Description

Rhagoletis cerasi can reach a body length of about 3.5–5 mm (0.14–0.20 in).[4] These small fruit flies have a shiny body, dark brown, almost black. Mesonotum shows silvery vittae. The wings are transparent, with four transverse dark stripes.[4] Eyes are green with reddish reflections. The head is brown, while scutellum and the legs are yellow.[5]

This species is very similar to Rhagoletis berberidis.[5]

Biology

The adults can be found from late May to early July.[4] They feed on the sugary secretions produced by the cherry itself or by insects (such as the aphid honeydew). After 10–15 days the females lay 50-80 eggs[4] one at a time in the pulp of the fruit. After 6–12 days[4] the eggs hatch and white legless larvae 4–6 mm long[4] come out and feed on the pulp of the fruit. During the ripening the larvae leave the fruit and pupate in the soil,[4] where they overwinter. Usually this species have one generation every 1–2 years.[4]

These fruit flies are considered a major pest of cherry crops [6] in Europe and Asia. They damage also the fruits of apricot, honeysuckle, barberry, bird cherry and snowberry.
