The EPPO Secretariat has developed computer software for Pest Risk Analysis (PRA) within the EC 7th Framework Programme PRATIQUE (Enhancements of Pest Risk Analysis Techniques) and with the support of the EPPO Panels. The software, Computer Assisted PRA (CAPRA), aims to assist pest risk analysts to run the EPPO Decision‐support scheme for pest risk analysis [EPPO Standard PM 5/3(5) Decision‐support scheme for quarantine pests], and other decision‐support schemes. It is freely avaliable on the EPPO website or on http://capra.eppo.org/.

The application of pest risk analysis (PRA) decision‐support schemes, such as that used by the European and Mediterranean Plant Protection Organization (EPPO), generates many ratings for likelihood or magnitude of risk factors, each with an associated uncertainty. In accordance with the international standard ISPM 11 (FAO, 2004), questions have been devised to assess the key elements of pest risk in the four main sections of pest risk assessment: Entry, Establishment, Spread and Impact. After completing each section, risk assessors are required to give a summary rating and an uncertainty score for that section. The large number of question ratings and uncertainty scores make the task of summarizing each section and its uncertainty quite difficult. Two graphical tools have been developed to aid this task: the PRA Risk score and uncertainty visualizer (Visualizer) and the Rule‐based matrix model (RBMM). The Visualizer presents a case summary graph on a single page in such a way that the risk assessors and peer reviewers can see rating scores and uncertainties in a pictorial manner; the RBMM integrates all the individual questions in the assessment through a hierarchy of rules that attempt to mimic the logic used by the assessors and are arranged in the form of a flow chart to give an overall rating with an accompanying expression of uncertainty.

The decision‐support scheme (DSS) for action at outbreaks developed under PRATIQUE (Enhancements of Pest Risk Analysis Techniques) brings together a set of guidance and tools, using the CAPRA application. The DSS is initiated by the collation of key information on the current outbreak situation, and then compares candidate measures in order to derive a strategy for action and/or contingency. It is hoped that this deliverable will assist national plant protection organizations (NPPOs) to address and justify eradication campaigns effectively. The rationale behind the DSS and its key features are presented and discussed.

In 2004, the EPPO Council expressed profound concerns about the decreasing expertise in plant protection and declared a state of emergency for Plant Health (‘Madeira declaration’). As diagnostics is one of the scientific fields which are vital for sustaining sound plant health policies, a questionnaire was launched and all EPPO member countries were asked to provide information about their diagnostic expertise, focusing on regulated pests or pests which may present a risk to the EPPO region. In 2006, results of the questionnaire were analysed and compiled by the EPPO Secretariat into a new database. This database now contains detailed information (contact addresses, quality programmes, and accreditations) for 80 diagnostic laboratories from 28 EPPO member countries. More than 500 experts are now registered with details about their diagnostic expertise (pests diagnosed and methods used). The EPPO database on diagnostic expertise can be freely accessed on the Internet: http://dc.eppo.org.
