  What is PQR?  
PQR is the EPPO database on quarantine pests. As decided by the EPPO Executive Committee in April 2007, it can be downloaded free of charge from this web page. PQR gives access to data on:
  • all the pests of the EPPO A1 and A2 lists and of EU Directive 2000/29, appearing in the EPPO/CABI publication "Quarantine Pests for Europe" (2nd edition)
  • pests added to these lists since that publication
  • pests of the EPPO Alert List
  • plants of the EPPO List of invasive alien plants
  • many other quarantine pests and invasive plants of interest to other regions of the world (data obtained from FAO, CABI or from the RPPOs).

For each pest, it is possible to obtain lists of host plants, commodities able to act as pathways in international trade, details of geographical distribution with maps, and pictures. Conversely, it is also possible to interrogate the database to obtain specific lists of pests, by stipulating the host species, the commodity, and the countries of interest. PQR contains general nomenclatural and taxonomic details on pests and hosts.

Example of general information that is provided for a specific pest:

What's NEW in PQR version 5?

  • New interface: a completely new interface has been designed to facilitate searches in the database.
  • Updated information: all new information collected by the EPPO Secretariat since the release of the previous version (PQR version 4.7 in 2007) has been included (i.e. data published in the EPPO Reporting Service since 2007 or obtained from CABI maps). In addition, all content of the 'EPPO Plant Protection Thesaurus' (EPPT - pest and plant names, EPPO codes) can be accessed in PQR.
  • Dynamic maps: new maps showing the world distribution of a pest (zoomable, printable, downloadable). By double-clicking on a country, you can read more details about the geographical record. When the distribution of a pest changes, the map is automatically updated.
  • Official pest status: when NPPOs have provided an official pest status (in the terms of ISPM 8), it is displayed in a text field.
  • Active links to the EPPO Reporting Service: when a Reporting Service article is quoted to describe the situation of a pest in a given country, the full article can be accessed by clicking on these links.
  • Lists of host plants and lists of geographical distribution can be printed and exported in different formats (Word, Excel, html, pdf, jpeg).
  • Pictures: when available, pictures of pests and invasive plants can be viewed in PQR.
