CAPSELLA. Shepherd's-purses. [Brassicaceae]

Two species of Capsella are recorded in Britain. These include the native Shepherd's-purse (C. bursa-pastoris) and the introduced Pink Shepherd's-purse (C. rubella). Two dipterous miners, the polyphagous agromyzids Chromatomyia horticola and Liriomyza strigata, are recorded on Capsella in Britain, and one of these is also recorded on Conringia, Hesperis, Lepidium and Raphanus. See BRASSICA. The agromyzids Liriomyza huidobrensis and Liriomyza trifolii, polyphagous pest species of ornamental and vegetable crops occasionally intercepted at UK points of entry, are recorded on Capsella. Both species have been found under glass in England and Wales. All populations have been and continue to be eradicated. Elsewhere the agromyzids Liriomyza bryoniae, Liriomyza huidobrensis, Liriomyza strigata and Liriomyza trifolii and the drosophilid Scaptomyza flava are recorded mining Capsella. No non-dipterous miners are recorded on Capsella in Britain.
