Chamaepsila rosae (Fabricius 1794) - (carrot fly)

This fly is native to Europe and has been introduced into North America (first record in 1885) and New Zealand. The larvae can cause serious damage to the tubers of carrots. The leaves of infested plants wilt and turn yollow. Yield can be seriously affected, even in its native range. The host range of the fly includes other Apiaceae.

Eggs are laid at the base of the plant and the hatching larvae burrow into the soil. There are 2-3 generations per year and the larvae or pupae are the overwintering stage. Management relies mainly on pesticides (Collier, 2009), but resistant cultivars and biological control methods are being explored.
