Liriomyza cepae (Hering, 1927)
Generally the mine begins as a fine corridor of variable length. Later the larva lives within the tubular leaves. Frass, at least partly, in green thread fragments. Pupation outside the mine.
Allium cepa, fistulosum, victorialis.
A pest on leek and onions (Darvas, Skuhravá & Andersen, 2000a).
Larvae in July-August (Hering, 1957a, 1962a), June and August (van Frankenhuyzen, Houtman & Kabos, 1982a).
BE recorded (De Clercq & D’herde, 1969a).
NE recorded: uncommon in the country, but the species can reach high densities in onion fields during hot summers (van Frankenhuyzen, 1977a; van Frankenhuyzen, Houtman & Kabos, 1982a).
LUX not recorded (Fauna Europaea, 2008).
distribution within Europe
From Scandinavia tot the Iberian Peninsula; also in Thrace; not in the British Isles (Fauna Europaea, 2008).
Yellow (Hering, 1957a) to reddish brown (Spencer, 1973b).
Amauromyza, Dizygomyza, Phytobia cepae.
Spencer (1973b) has split off another species, L. nietzkei, from cepae. Moreover, a description of “cepae” by Sasakawa (1961a) turned out to refer to a third species, L. chinensis (Kato, 1949) (Dempewolf, 2004a). L. nietzkei is known with ceertainty from Germany, France, and Italy, and chinensis has been found in southern France, but probably they are distributed wider – either naturally or through human transport. The name cepae in the older literature may obviously refer to different species.
