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

David Makowski

Résumé

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 the simplified[1] pest risk assessment conducted by France on Aceria sheldoni (Ewing) (Acari: Eriophyidae), with French Guiana, Guadeloupe, Martinique and Réunion considered as endangered area. A. sheldoni the citrus bud mite, is a minute (0.12 - 0.18 mm), elongate mite that is reported from citrus and related plant species. The immature and adult stages feed mostly beneath bud scales or in developing buds and flowers, damaging embryonic bud tissues. Plant parts (twigs, flowers and fruits) that develop from damaged buds are often distorted. This species is widely distributed around the world almost everywhere where citrus is cultivated. 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 and terminology 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)] and the terminology of ISPM No. 5 [Glossary of Phytosanitary Terms (2007)] by the International Plant Protection Convention (FAO, 2007). The conclusion of the French assessment is that A. sheldoni should be maintained as a quarantine pest for the French overseas departments pending more accurate data on its harmfulness in tropical conditions. However, insufficient information is provided in the simplified risk assessment to support this conclusion. Many statements are not substantiated by references nor supported by verifiable data, particularly with regard to: 1) possible entry pathways, 2) existing pest management measures and 3) potential economic impact of the organism in the PRA area. After a detailed analysis of the material provided in the French document and study of additional literature, the Panel agrees that A. sheldoni can enter and establish in the PRA area, but consider the potential for economic consequences to be low. It is seldom reported to occur on citrus hosts other than lemon. Despite its wide distribution, including areas with similar climates to the PRA area, several studies show a low potential of this mite to cause economic damage on lemons. Moreover, citrus is acknowledged in the French assessment as not a major factor in the economy. Lemon is grown for home consumption and not for export, and thus the consequences of A. sheldoni on the local market are considered to be very limited. Therefore, the Panel considers that A. sheldoni is not appropriate for consideration of risk management options for French Guiana, Guadeloupe, Martinique and Reunion, and thus is not potentially eligible for addition to the list of harmful organisms in Directive 2000/29/EC.
