Alien insect species in Lithuania
In their paper, Ivinskis et al. (2009) provide useful details on the current situation of several insect pest species of recent introduction in Lithuania. The EPPO Secretariat has extracted data on the following species:
Bemisia tabaci (Hemiptera: Aleyrodidae – EPPO A2 List) was detected in 2007 in glasshouse ornamentals, but was successfully eradicated.
Cameraria ohridella (Lepidoptera: Gracillariidae - formerly EPPO Alert List) was first found in Lithuania in 2002, in the Curonian Spit (sand dune that separates the Curonian Lagoon from the Baltic Sea). In 2009, it was reported in more than 100 localities affecting horse-chesnut trees (Aesculus hippocastanum).
Liriomyza huidobrensis (Diptera: Agromyzidae – EPPO A2 List) is regularly detected in imported ornamental plants. In 2005, an outbreak was detected in the region of Vilnius but was successfully eradicated.
Phyllonorycter issikii (Lepidoptera: Gracillariidae - formerly EPPO Alert List) was first reported in Lithuania in 1998. This leafminer of Tilia spp. is now widespread and has developed high populations in some areas.
