  • Abstract : 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 pest risk assessment conducted by France on Odoiporus longicollis with French Guiana, Guadeloupe, Martinique and Réunion considered as endangered area. Odoiporus longicollis, the banana stem weevil, occurs in India, China, Malaysia, Indonesia and Thailand where it is a key pest of bananas and plantains. The adult weevils are nocturnal, black-coloured, relatively large (23-39 mm), strong-flying beetles. All life stages are present throughout the year in the infested plant. Damage is caused by the larva tunneling inside the pseudostem of the banana plant, weakening the plant that is unable to bear the weight of the fruit. Up to 90% yield loss can result. Control is by cultural methods and injecting pesticides into the stem. 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: Pest risk analysis for quarantine pests including analysis of environmental risks and living modified organisms (2004) by the International Plant Protection Convention (FAO, 2007b). Although the pest risk assessment could be improved in the analysis of entry pathways and the analysis of economic, social and environmental consequences in case of establishment, the Panel agrees with the conclusion of the French document that : the probability of entry of O. longicollis into the PRA area is moderate. O. longicollis has a very high probability of establishment and spread, due to the widespread distribution of its host plants, banana and plantain in the PRA area and the impact of pest infestation on the host plant is high. Additionally, Musa spp. fruits are widely grown in the PRA area and are of particular economic importance as an export crop for Guadeloupe and Martinique. If the species became established in these two islands, export markets for banana could be seriously affected and additional control costs may reduce competitiveness. Smallholdings producing fruit for the local market or for home-consumption could suffer yield losses impacting on production and consumption patterns, with related negative social impacts, should the yield of plantain be substantially reduced. Similar effects are possible for French Guiana, where banana is also grown in shifting cultivation. Uncertainties exist concerning the importance of different possible entry pathways, some biological features of the pest, and the potential for social and environmental consequences, but these are not expected to affect the conclusions reached by the Panel. The Panel concludes that O. longicollis is appropriate for evaluation of pest risk management options for the endangered areas of French Guiana, Guadeloupe, Martinique and Réunion and thus potentially eligible for addition to the list of harmful organisms in Directive 2000/29/EC.
