Update of the Xylella spp. host plant database

Following a request from the European Commission, in 2015 EFSA created a database of host plant species of Xylella fastidiosa (EFSA, 2015). In 2018, a renovated and updated database of Xylella spp. (including both species X. fastidiosa and X. taiwanensis) and the related scientific report were published (EFSA, 2018). EFSA is going to maintain and update this database periodically.

In April 2020, EFSA released a new update of the Xylella spp. host plants database with information retrieved from literature search up to June 2019, Europhyt outbreak notifications up to 15 October 2019, and personal communications of experts (EFSA, 2020). The applied protocol for the extensive literature review, data collection and reporting, as well as results and lists of host plants are described in detail in the scientific report (EFSA, 2020).

The current database includes 343 host plants species in which the infection was assessed with at least two highly reliable detection methods (category A – see section 2.5.2 of EFSA (2020)), up to 595 host plants (regardless the detection methods applied – category E, see section 2.5.2 of EFSA (2020 ).

The Excel Files here attached represent the VERSION 3 of the Xylella spp. host plants database. For a detailed description of the information included in the database, please consult the related scientific report (EFSA, 2020).

The Excel file “Xylella spp. host plants database - VERSION 3” contains several sheets: the LEGENDA (with extensive description of each table), the full detailed raw data of the Xylella spp. host plant database (sheet “observation”) and several examples of data extraction.

Additional Excel files contain lists of host plant species of X. fastidiosa (subsp. unknown (i.e. not reported), fastidiosa, multiplex, pauca, morus, sandyi, tashke, fastidiosa/sandyi) and X. taiwanensis with different infection methods (natural, artificial and not specified, and according to different categories (A,B,C,D,E – see section 2.5.2 of EFSA (2020)).
