Leaf-mine:
A short, irregular, linear upper surface mine on any part of
the leaf. Also recorded from young pods (Bland, 1997a). The mine is
illustrated in Nederlandse
bladmineerders.
Larva: The larva is described by Dempewolf (2001: 148). Puparium: Pale yellowish-brown; posterior spiracles each with an ellipse of 7-12 bulbs. Comments: A highly polyphagous species principally mining Cucurbitaceae and Solanaceae, although recorded on hosts in numerous other plant families. A pest of tomatoes in glasshouses. A significant pest on several genera of cultivated cucurbits in Europe, but rarely found on its original host Bryonia (Spencer, 1990). Hosts cited here include 119 plant genera in 31 plant families of which only 4 plant genera in 2 plant families are records in Britain. A serious pest in the Mediterranean area of tomatoes and has been recorded as a pest of tomatoes in glasshouses in England, The Netherlands and Denmark. In France tomatoes, melon, cucumber and lettuce have been attacked (Spencer, 1973a). In Northern Ireland Liriomyza bryoniae is a notifiable pest species. If you suspect the presence of this species, please contact the Plant Health and Seeds Inspectorate (tel: 01904 455174, e-mail: planthealth.infodefra.gsi.gov.uk). However, in order to be certain of its identity, the male genitalia should be critically examined. Diagnostic protocols may be found at www.csl.gov.uk/specialInterest/liriomyza.pdf. See also Collins (1996). Bland (1997a) records mines of bryoniae in young seed pods of Pisum sativum - mangetout purchased in Scotland - which, from enquiries he made, suggested came from southern France. Minkenberg & Lenteren (1986) review the hosts and parasites of Liriomyza bryoniae. Hosts in Britain:
