Liriomyza huidobrensis (Blanchard, 1926)
Corridor; usually the mine begins with a short upper-surface stretch, then continues lower-surface, in the sponge parenchyma. Often the mine follows the midrib or a thick lateral vein for long distances. Most mines are found in the basal half of the leaf. Frass in thread fragments and strings (according to Steck, 2002a, in a central line). Pupation outside the mine.
Dicots, strongly polyphagous
BE recorded (Scheirs, De Bruyn & von Tschirnhaus, 1995a).
NE recorded de Goffau (1991a).
LUX not recorded (Fauna Europaea, 2008).
distribution within Europe
Practically cosmpolitain; in temperate regions mainly in greenhouses.
Rear spiraculum with 6-9 papillae, arranged in an ellipse. (Darvas, Skuhravá & Andersen write erroneously that the front spiraculum has this number of papillae.). Third instar larvae have antero-dorsally a yellow-orange spot.
Yellowish to reddish brown.
Liriomyza cucumifoliae Blanchard 1938; L. decora Blanchard, 1964; L. dianthi Frick, 1958; L. langei Frick, 1951. However, many authors do consider L. langei a separate species, that is exceedingly difficult to separate fro huidobrensis (Dempewolf, 2004).
Originally a South-American species, that has developed into a major pest of cultivated plants all ver the world (Darvas, Skuhravá & Andersen, 2000a; Steck, 2002a; Central Science Laboratory, UK, 2004a). It was first seen in the Netherlands in 1989, on a wide variety of crops like lettuce, iceberg lettuce, gypsophila and tomato (de Goffau, 1991a). In our regions mainly a problem in greenhouses, but cases have been documented of hibernation in the open (Van der Linden, 1993a), and in summertime considerable damage can be caused in field crops (Oudman e.a. 1993a). The observation in Belgium cited above was done on adult flies in a nature reserve. Among others Dempewolf (2004a), Parella & Bethke (1984a), Prando & da Cruz (1986a) and Spencer (1973b) give details on the biology and control of this species.
