Pest risk assessment made by France on Prays endocarpa considered by France as harmful in French overseas departments of French Guiana, Guadeloupe, Martinique and Réunion - Scientific Opinion of the Panel on Plant Health

Following a request from the European Commission, the Panel on Plant Health was asked to deliver a scientific opinion on 30 pest risk assessments made by France on organisms which are considered by France as harmful in four French overseas departments, i.e. French Guiana, Guadeloupe, Martinique and Réunion. In particular, the Panel was asked whether these organisms can be considered as harmful organisms for the endangered area of the above departments, in the meaning of the definition mentioned in Article 2.1.(e) of Directive 2000/29/EC and thus potentially eligible for addition to the list of harmful organisms in Directive 2000/29/EC.This document presents the opinion of the Panel on Plant Health on the simplified[1] pest risk assessment conducted by France on Prays endocarpa with French Guiana, Guadeloupe, Martinique and Réunion considered as endangered area.Prays endocarpa Meyrick (Insecta: Lepidoptera: Yponomeutidae), the citrus rind borer or citrus pock caterpillar, is usually found on Citrus, but has also been reported to attack other Rutaceae, including the bael tree Aegle marmelos. The larva feeds on the rind of different citrusfruit, causing gall-like swellings (pocks). Larval development is completed within these galls and the larvae never enter the endocarp. This species is distributed in parts of the Indian subcontinent, South-East Asia and the Pacific.The Panel examined in detail the risk assessment provided, and considered the accuracy and quality of the information provided and methods applied for pest risk assessment purposes. The review was based on the principles of the International Standard on Phytosanitary Measures ISPM No. 11[2]: Pest risk analysis for quarantine pests including analysis of environmental risks and living modified organisms (2004) by the International Plant Protection Convention (FAO, 2007).The Panel concludes that:* Many statements in this simplified risk assessment are neither substantiated by references nor supported by verifiable data. This applies to, amongst others, i) the possible introduction pathways, ii) the climatic similarities between the PRA area[3] and the area where the pest is currently distributed, iii) the size of the area under cultivation with susceptible hosts and the economic importance of these hosts in the PRA area, iv) current or potential control strategies, and v) the potential impact in the PRA area.* Information given in the pest risk assessment on the related species Prays endolemma, reported from the Philippines, is irrelevant for the pest risk assessment on P. endocarpa. It is recommended that this species be treated in a separate pest risk assessment.* The Panel considers the probability of entry to be very low, given the lack of trade in citrus fruit between the area of current distribution of P. endocarpa and the PRA area. Moreover, symptoms of infested fruit are very conspicuous and contaminated batches of citrus fruits could easily be detected prior to export. For the same reason, it is unlikely that passengers would carry infested citrus fruit the long distances from countries where P. endocarpa occurs into the PRA area.* The Panel agrees that the probability of establishment is very high, should the pest gain entry in the PRA area, given the presence of suitable host plants (citrus) and the fact that the pest is currently distributed in areas with similar climatic conditions to those in the PRA area.* The conclusion of the pest risk assessment that economic impacts would be "moderate to high" cannot be supported by the information given in the French document or that available in the literature. There is only sparse evidence of the harmfulness of P. endocarpa to citrus crops in its area of current distribution. In the majority of its current range, the organism is considered a minor pest of citrus and evidence of economic damage is confined to a limited number of reports in Indonesia. Varieties of citrus may differ in their susceptibility to the pest, but the pest risk assessment does not provide any information on cultivars of the different citrus crops grown in the PRA area.The degree of uncertainty is high, given the lack of data provided in the assessment and available in the scientific literature on the biology and impact of the organism.The Panel, based on the information provided in the document and on additional literature consulted, concludes that P. endocarpa is not appropriate for evaluation of pest risk management options for the French overseas departments of French Guiana, Guadeloupe, Martinique and Réunion and is thus not potentially eligible for addition to the list of harmful organisms in Directive 2000/29/EC
