Dipteran leafminers in the vicinity of glasshouses and plant markets in Lithuania*

Areas surrounding the glasshouses of 60 growers, and 16 plant markets, were surveyed in 2001/2003 to determine the distribution of dipterous leafminers in Lithuania, including regulated species. In total, 152 species belonging to 7 families were discovered, and the infested host plants represented 46 families. The relative frequency of Liriomyza bryoniae was 32% in the vicinity of glasshouses and 19% in market places. This species attacked plant genera such as: Amaranthus, Beta, Bryonia, Chenopodium, Cucumis, Datura, Gypsophila, Lycopersicon, Nicandra, Nicotiana, Physalis, Petunia, Sisymbrium, Solanum, Spinacia and Viola. The same plant genera also potentially provide sites for the survival of economically important species, Liriomyza huidobrensis and Liriomyza trifolii, in Lithuania.
