DAUCUS. Carrots. [Apiaceae]

Nine species of Daucus are recorded in Britain. These include the native Carrot (D. carota), Sea Carrot (D. carota gummifer) and Wild Carrot (D. carota carota). Two dipterous miners, the agromyzids Phytomyza chaerophylli and Napomyza carotae, are recorded on Daucus in Britain. The agromyzid Phytomyza chaerophylli is also recorded on Chaerophyllum, Conopodium, Torilis, and possibly Sison in Britain. The agromyzids Liriomyza huidobrensis, Liriomyza sativae and Liriomyza trifolii, polyphagous pest species of ornamental and vegetable crops occasionally intercepted at UK points of entry, are recorded on Daucus. Liriomyza huidobrensis and Liriomyza trifolii have been found under glass in England and Wales. All populations have been and continue to be eradicated. Elsewhere the agromyzids Chromatomyia syngenesiae, Liriomyza huidobrensis, Liriomyza sativae, Liriomyza trifolii, Phytomyza chaerophylli, Napomyza carotae and the tephritid Euleia heraclei are recorded mining Daucus. Two non-dipterous miners are recorded on Daucus in Britain (see below).
