MATRICARIA. Scentless Mayweed [Asteraceae]

Seven species of Matricaria are recorded in Britain. These include the native Scentless Mayweed (M. recutita). Three dipterous miners, the agromizids Chromatomyia 'atricornis', Chromatomyia syngenesiae and Ophiomyia curvipalpis, are recorded on Matricaria in Britain, although he latter record requires confirmation. See ACHILLEA. The agromyzid Liriomyza huidobrensis, a polyphagous pest species of ornamental and vegetable crops occasionally intercepted at UK points of entry, is recorded on Matricaria and has found under glass in England and Wales. All populations have been and continue to be eradicated. The agromyzid Napomyza lateralis feeds in the stems of Anthemis, Bidens, Calendula, Dimorphotheca, Matricaria, and Senecio in Britain, although it has also been found in the inflorescence of Matricaria (Spencer, 1972). Elsewhere the agromyzids Chromatomyia horticola, Chromatomyia syngenesiae, Liriomyza huidobrensis, Liriomyza ptarmicae, Liriomyza strigata, Ophiomyia curvipalpis and Phytomyza pullula and the tephritid Trypeta zoe are recorded mining Matricaria. Elsewhere the agromyzid Napomyzxa lateralis is recorded boring stems of Matricaria. No non-dipterous miners are recorded on Matricaria in Britain.
