#METABASE Q UPDATE#

However, several genera and complex species cannot be reliably identified using this gene. This molecular database supports reliable identification of most quarantine species of Arthropods included, mostly using a 658-base pair fragment in the gene encoding the mitochondrial cytochrome c oxidase 1 (COI), corresponding the standard barcode as defined by Hebert et al. Warning regarding the identification of quarantine Arthropods using barcoding When the BLAST query does not match or when the best similarity rate is less than 98%, the identification should be considered as undetermined or uncertain, but not negative. Thus, it is recommended to consult the list of taxa included to verify that the targeted species is included. : The EURL for insects and mites provided 97 new sequences to EPPO-Q-bank covereing 12 new species for which sequences were not available before and 34 species for which sequences were available but for which a wider variability is now covered.Īlthough EPPO-Q-bank is the most complete database for quarantine arthropods for Europe, several species are still missing. This new data was generated by the Royal Museum for Central Africa and was provided to EPPO-Q-bank within the framework of the EU Horizon2020 project ‘ FF-IPM ’ (grant agreement 818184). 127 new Tephritidae species are now represented in the database.

: A major update of the arthropod section of EPPO-Q-bank was made for the Tephritidae family with the addition of 836 new specimens and their respective COI sequence. The distribution as well as relevant EPPO-protocols for Arthropods can be downloaded from the EPPO Global Database NEWs To facilitate, identification of quarantine species about 100 closely related species have been sequenced (including also some pests).Ī list of references used for the development of the Arthropods database can be consulted.

Most species sequenced originate from Palearctic and Nearctic regions.

The choice was made to sequence the mitochondrial Cytochrome c oxydase I standard barcode fragment (COI) as well as the nuclear internal transcribed spacer 2 (ITS2) to provide a reliable identification tool for all developmental stages of those Q-arthropods and congeneric pest species. Currently, the EPPO-Q-bank Arthropod database contains DNA sequences ( barcodes) of quarantine arthropod species for Europe and their closest relatives. Loomans (NVWA, the Netherlands) and collaborators between 20. Qbank's Arthropods database was first designed and developed as part of the QBOL project by J.-Y.
