The EPPO Decision‐support scheme (DSS) for Pest Risk Analysis (PRA) was fundamentally revised by the PRATIQUE EU project. Based on the examples of Polygonum perfoliatum (mile‐a‐minute‐weed) and Eichhornia crassipes (water hyacinth), its applicability for invasive alien plants was tested. By means of a comparison of the risk analysis procedures with EPPO schemes before and after the project, pest group specific enhancements are outlined. For the two plants tested here, documented invasion history as well as biotic and abiotic requirements show that they can establish and spread in Europe and cause damage. PRATIQUE revisions to the EPPO DSS increased transparency, user friendliness and consistency for PRAs on invasive alien plants. This was accomplished through more comprehensive rating guidance, and aspects such as allowing individual risk elements to be documented and summarized to give a conclusive end result. 相似文献

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/ . 相似文献

PRATIQUE is an EC-funded 7th Framework research project designed to address the major challenges for pest risk analysis (PRA) in Europe. It has three principal objectives: (a) to assemble the datasets required to construct PRAs valid for the whole of the EU, (b) to conduct multi-disciplinary research that enhances the techniques used in PRA and (c) to provide a decision support scheme for PRA that is efficient and user-friendly. The research will be undertaken by scientists from 13 institutes in the EU and one each from Australia and New Zealand with subcontractors from institutes in China and Russia. They will produce a structured inventory of PRA datasets for the EU and undertake targeted research to improve existing procedures and develop new methods for (a) the assessment of economic, environmental and social impacts, (b) summarising risk while taking account of uncertainty, (c) mapping endangered areas (d) pathway risk analysis and systems approaches and (e) guiding actions during emergencies caused by outbreaks of harmful organisms. The results will be tested and provided as protocols, decision support systems and computer programs with examples of best practice linked to a computerised European and Mediterranean Plant Protection Organization (EPPO) PRA scheme. 相似文献

This paper describes the efforts in the PRATIQUE EU project to increase consistency that were integrated into the revised EPPO Decision‐support scheme (DSS) for Pest Risk Analysis (PRA). The establishment section is used here to illustrate the changes and improvements of the DSS, as it has undergone the most comprehensive changes with reformulation and restructuring of many questions and detailed rating guidance. When revising the establishment section of the EPPO DSS for PRA, there were three principal objectives that influenced the revision: (i) to focus the assessment on the most relevant factors influencing establishment; (ii) to identify the area where establishment is possible before assessing the suitability of that area, and (iii) to enhance the consistency of the establishment section by providing rating guidance with sub‐questions and examples. To simplify the process, some questions were rephrased as closed questions (answer is either yes or no). Clearer notes were provided to explain what information is needed to answer the questions. Furthermore, consistency has been enhanced by developing tools to help assessors when deciding on an appropriate overall risk rating and uncertainty score by providing a visual summary of the risk ratings and uncertainty scores (‘Visualizer’) and a method for integrating all the responses to the questions to provide a summary score for each major section and an overall assessment of risk (‘Rule based matrix model’). 相似文献

Assessing the potential environmental impact of alien plants and plant pests is notoriously difficult. New protocols have been developed in the framework of the EC project PRATIQUE to provide guidance on environmental impact assessment in the EPPO pest risk analysis (PRA) decision‐support scheme and enhance consistency between risk assessors and risk ratings for different pests. A set of questions with rating guidance and examples is provided, and individual scores are summarized into final scores, using a hierarchy of risk matrices, to assess current and potential environmental impacts. Two separate protocols are available: for alien plants and for other pests. These protocols could also be used to assess environmental impact in other PRA schemes as well as to assign alien species to regional black lists or to prioritize species for management decisions. 相似文献

This paper summarizes the approach of a recent EPPO study and some of its key outputs. The study was commissioned to aid pest risk analysis and the development of risk management measures for movements of woodchips and other similar commodities. These wood commodities represent a significant pathway for the introduction of pests of trees into new areas, and the pathway is becoming more important as trade in such commodities increases. An indication of the relative risk of different commodities for different types of pest was proposed as a conclusion of the study. More information is now needed on the quantities and nature of the material being moved into and within the EPPO region, and the treatments to which it has been subjected. This may not be clear from commercial documentation and trade data so national plant protection organizations (NPPOs) are encouraged to gather and share such information from inspections of consignments. 相似文献

The assessment of the suitability of the climate for pest establishment is an important part of pest risk analysis (PRA). This paper describes the work undertaken by the EU 7th Framework project PRATIQUE (Enhancements of Pest Risk Analysis Techniques) to develop guidance for this component of PRA. Firstly, there is a guide to rating the suitability of the climate in the PRA area using qualitative methods. Secondly, a Decision‐support scheme (DSS) has been created to assist analysts in deciding whether to map climatic suitability, and to guide the selection of the most appropriate method from the large number available. The process of selecting a climatic mapping method is based on a review of the pest’s climatic responses and distribution. A spreadsheet provides a comparison of the potential problems that can arise, depending on the mapping method and on the amount and quality of available data. Diagrams are provided to help choose the location data category that best represents the possible biases in the known distribution of the pest. A second spreadsheet provides general information on the differences and similarities of each method in terms of categories such as functionality, ease of use and quality assurance. A variety of data, tools and supporting documents are available as appendices to the DSS. All of the tools and guides are freely available online. 相似文献

The hemlock looper, Lambdina fiscellaria (Guenée), is a serious forest pest in North America with three subspecies that vary in their geographical range and larval host preferences. Both broadleaved and coniferous trees are infested, though the largest impacts are on coniferous forestry where trees can be completely defoliated and killed. The pest was identified as a potential threat to forestry on the island of Ireland during a horizon‐scanning exercise to identify pests of Picea sitchensis (Bong.) Carr. (Sitka spruce) and was subject to a rapid pest risk analysis (PRA). Though judged to be unlikely, pathways identified were uncontrolled wood commodities and mosses and lichens harvested from forests in North America and exported for use in ornamental displays. Lambdina fiscellaria is found in a range of climate types, and is likely to be able to complete its lifecycle in the Irish climate – although there is uncertainty concerning its ability to adapt to European trees. Lambdina fiscellaria has only a limited capacity for spread, as virgin females are burdened by their eggs and are poor fliers. This was judged to reduce potential impacts in the PRA area – as the slow rate of spread would provide time to develop monitoring and control methods well ahead of the pest reaching its maximum extent on the island of Ireland. The pest still poses a considerable risk to coniferous forestry not only on the island of Ireland but across the EPPO region where climate is suitable for the pest to establish. Regulation and implementation of phytosanitary measures prevent introduction of the pest should be considered. 相似文献

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. 相似文献

A quantitative pathway model, QPAFood, has been designed to support risk assessment for plant pest entry into European Union (EU) territory on a range of edible plant commodities via trade flows. The model calculates the distribution of an imported infested/infected commodity along a pathway into and within the EU from source countries, based on Eurostat data and other data/information. The model determines the implications of global trade pathways for the potential arrival of the infested commodity in the EU28 Member States. Within each Member State, the calculation proceeds by distributing the commodity according to uses, notably retail or processing, to the vulnerable area of commercial host crops determined in each NUTS2 region and then quantifies the consequent potential for pest–host contact which could lead to pest transfer. Annual and monthly estimates of contact risk are tabulated and visualized for Member States and NUTS2 regions. The model was developed originally for the European Food Safety Authority using four case studies of specific pest–commodity combinations. These pests had relatively limited host ranges and the model has now been extended in the context of the EC FP7 DROPSA project for the multiple commodity pathways associated with the highly polyphagous fruit pest Drosophila suzukii. 相似文献

Solanum elaeagnifolium Cav., originating from the Americas, has been unintentionally introduced in all the other continents as a contaminant of commodities, and is considered one of the most invasive plants worldwide. In the Euro‐Mediterranean area, it is a huge threat in North African countries. It is also present in European Mediterranean countries (France, Greece, Italy and Spain), but still has a limited distribution. Through a logical sequence of questions, pest risk analysis (PRA) assessed the probability of S. elaeagnifolium entering, establishing, spreading and having negative impacts in European and Mediterranean countries. As this assessment revealed that the entry of the pest would result in an unacceptable risk, pest risk management options were selected to prevent the introduction of the plant. Preventive measures on plants or plant products traded internationally may directly or indirectly affect international trade. According to international treaties, PRA is a technical justification of such international preventive measures. 相似文献

A pest risk assessment was performed according to the EPPO Standard PM 5/3 to determine the probability of introduction of Monilinia fructicola into the countries of the European Union (EU) and its potential economic impact. Data on the biology of the pathogen were combined with trade pathways and information on the use of commodities in order to quantify risk. On the basis of the EPPO Standard, we concluded that there is a serious risk that M. fructicola could become established in the EU, with significant economic losses as a result. This justifies the phytosanitary measures currently in place in the EU. 相似文献

The widely used Köppen–Geiger climate classification system can inform judgements of establishment during pest categorizations and systems of simplified pest risk assessment. Such processes allow national plant protection organizations to quickly identify plant pests of potential regulatory concern. Judging whether a pest can establish is a key factor in determining whether a pest satisfies the definition of a quarantine pest. Climate is often a significant factor influencing where species can establish. Here, we provide a resource that reports the Köppen–Geiger climate classification at a range of spatial scales from sub‐national to continental for the period 1986–2010 in an accessible table. The data is provided as a resource for pest risk analysis to inform and support rapid decision‐making. An online appendix is provided showing the number of grid cells in each of the 31 Köppen–Geiger climate types in 417 regions across the globe at country level or less. Thirteen climate types occur within the European Union (EU), the most common is ‘temperate oceanic’ occupying 48% of EU grid cells. Twenty‐four of 31 climate types occur within the EPPO region; the most common is ‘continental, uniform precipitation with cold summer’, occupying 35% of EPPO grid cells. 相似文献

An analysis of the risk to the countries of the European Union from a possible introduction of Bursaphelenchus xylophilus and its vectors in the genus Monochamus is performed by assembling relevant biological, climatic and commercial information. The risks presented by different trade pathways are assessed and phytosanitary measures to reduce the risks are proposed. The conclusion of the PRA, based on EPPO PRA guideline no. 1, is that these pests present a serious risk to European coniferous forests. 相似文献

A model of the decision‐support scheme for express pest risk analysis using a Bayesian network implemented in Excel 下载免费PDF全文
下载免费PDF全文 A model was developed to accompany the EPPO decision support scheme for express pest risk analysis (PRA) and provide a calculated overall risk and uncertainty for the PRA and so act as a reference for the judgement of overall risk and uncertainty provided by expert working groups. Implemented in Excel, it is readily accessible to PRA practitioners and offers: (a) a consistent and explained weighting of the different risk factors and a rationale for the way they are combined, (b) a calculated integration of the risk factor distributions to facilitate judgement of overall uncertainty, and (c) an account of the interaction between the rating and the uncertainty score so that, for example, an overall rating of moderate is not necessarily used to reflect uncertainty about assessments in which the risk is neither obviously high nor low. Of the nine published express PRAs examined, the rating and uncertainty predicted by the model were: in agreement with five; differed in both rating and uncertainty in one case; differed in rating only in one case; and differed in uncertainty only in two cases. Possible reasons for these differences were examined and the interpretation of model results to inform assessments is discussed. 相似文献
