Carrot fly life cycle and management in carrots
Carrot flies overwinter as larvae or diapause pupae in soil and emerge as adults in spring to lay eggs near carrot plants.

Detail description
Carrot fly (Psila rosae/Chamaepsila rosae) infestations damage carrot roots through larval feeding. Adults emerge in spring, lay eggs near plants, and larvae tunnel into roots. Overwintering occurs as diapause pupae or larvae; pupation occurs in spring. Timing of generations varies by climate, with potential aestivation in hot conditions. The model forecasts adult emergence and egg-laying using soil and air temperature data, supporting targeted monitoring and control.
