Carrot Fly
The carrot fly (''Chamaepsila rosae'') is a pest of gardens and farms, and mainly affects the crop of carrots, but can also attack parsnips, parsley and celery. It is a member of the family Psilidae (order Diptera). Larvae Crop damage is caused by the creamy-yellow larvae (maggots) feeding on the outer layers of the carrot root. In autumn, they may penetrate further into the root. The legless larvae are up to 10 mm in length. Symptoms of infestation Foliage becomes wilted and discoloured. Leaves turn rusty red to scarlet with some yellowing. Rusty-brown tunnels are seen under the outer skin of mature roots. Control The flies lay their eggs around the developing carrots; the larvae, once hatched, burrow into the root. As female carrot flies are very low flying, the best method of prevention is to erect a barrier around the crop at least 2 feet (60 cm) high. Alternatively horticultural fleece may be used as a floating mulch to cover the crop. Because the carrot fly is attr ...
