1 Supplementary material of Vänninen, I., Worner, S., Huusela-Veistola, E., Tuovinen, T., Nissinen, A. and Saikkonen, K Recorded and potential alien invertebrate pests in Finnish agriculture and horticulture. Agricultural and Food Science 20: Appendix 1. Alien invertebrate pest species recorded in Finnish agriculture and horticulture by 2010 (species present in or known to have attempted invasion at least once). For the risk index generated by the SOM analysis, see Tables 2 and 3. For species mentioned in Vappula (1962) and marked with after the species name, the reader is advised to consult Vappula (1962) for original authors reporting the species as present in. codes: F=field (row) crops, FN=outdoor woody plant nurseries, FF=outdoor fruit and soft fruits, G=greenhouse crops, HP=herbs and herbaceous perennials, D (A)=species is alien for Europe (DAISIE 2008), D ( E) = of European origin but has spread outside its initial range in Europe, D ( C)=origin obscure. The following abbreviations show the estimated or known invasion status of the alien species (for further explanations, see Material and methods): Trans= transported to FI, not established; Erad=eradicated when detected; Col=in colonizing ; Est=established; Lspread=landscape spread (forming independent populations); Mig=migrant (natural spread) Nat=naturalized;? = has been detected at least once, but no information available on current invasion. Unspec = unspecified (in column). Pest status codes: 1A = has a protected zone status for the pest either in the whole country or in designated areas (EC 2000, MMM 2008); 1B = harmful organisms whose introduction into, and spread within, all member states shall be banned if they are present on certain plants and plant products (EC 2000); 2 = regulated non-quarantine pest according to Finnish plant health legislation's decrees on the production of seedling materials of vegetables, ornamental plants and fruit and berry plants (MMM 1996, MMM 2000, MMM 2010) (when species name is specifically mentioned in these decrees) EPPO A1 list pest (EPPO 2009a), EPPO list pest (EPPO 2009b), EPPO Alert list pest (EPPO 2010); 3 = nonregulated pest 1A, 1B Insecta Coleoptera Chrysomelidae Leptinotarsa decemlineata in First Risk index record in (SOM) F Trans/Erad Est.

Eradication attempts have so far been unsuccesfull. The species is an omnivore and is used as a biocontrol agent of whiteflies in the Mediterranean countries. It reroduces very rapidly in the year-round tomato crops in and is able to cause economic damage if left uncontrolled. FN Col/Est Est.

Meloidogyne hapla cannot increase in population size in Finnish climatic conditions 22 years ago (22). The importance of other Meloidogyne spp. that are occasionally transported to greenhouses is currently very small owing to the use of bagged rockwool and peat as growth substrates instead of soil.

Regulated pests (Finnish and EU plant health system, EPPO pest lists) and their risk indices as obtained using the SOM-method, in addition with selected scale insect pests that are not regulated but were often detected in greenhouses in a survey conducted in France. This table contains species that were not included in Appendix 1 or Tables 2 and 3. Risk indexes could not be calculated for all regulated species, because not all of them are included in the CABI (2003) database used used in the SOM analysis (the same concerns scales found in the French survey).
