| description | This pest survey card was prepared in the context of the EFSA mandate on plant pest surveillance (M-2020-0114), at the request of the European Commission. Its purpose is to guide the Member States in preparing data and information for Pseudocercospora angolensis surveys. These are required to design statistically sound and risk-based pest surveys, in line with current international standards. The fungus P. angolensis is a clearly defined taxonomic entity affecting Citrus species. Pseudocercospora angolensis is a Union quarantine pest not known to occur in the EU. The import of host plants is prohibited from third countries while special requirements are in place for the import of host fruit, which is the main pathway for the entry of this pest into the EU. Pseudocercospora angolensis produces conidia on lesions in plant tissues that can be disseminated by wind and/or rain, but dispersal distances are not known. Mild temperatures and prolonged periods of wetness are necessary for infection. Lesions on the leaves and fruit appear two to three weeks after infection. All commercial citrus species are susceptible to the fungus. Due to the wide availability of host species and climatic suitability, all citrus-growing areas in the EU are considered potentially suitable for the establishment of the pest. Long-distance spread is likely to occur through the movement of infected plant material. To increase the likelihood of detecting the pest, visual examination of symptoms should preferably be conducted in autumn before the harvest period. Symptoms caused by P. angolensis are non-specific; therefore, visual examination should be followed by molecular tests to identify the pest. Three main approaches for identifying P. angolensis in the laboratory are presented. Based on the analyses of the information on the pest–host plant system, the various units that are needed to design a survey should be defined and tailored to the situation in each Member State. |
