Megjegyzések:The EFSA Panel on Plant Health was requested by the European Commission to assess the risk to plant health in the European Union if the Australian bud-galling wasp Trichilogaster acaciaelongifoliae was released for the control of the invasive alien plant Acacia longifolia in Portugal. T. acaciaelongifoliae feeds on A. longifolia and A. floribunda. In South Africa, following its intentional introduction in 1982 and 1983, the wasp is now present throughout the range of A. longifolia in that country, with most plants showing galls and seed set reductions of, initially, up to 95 %. Climatic conditions in the EU are largely suitable for establishment wherever A. longifolia and A. floribunda are present. T. acaciaelongifoliae is moderately likely to establish and spread in the EU, by natural means, but particularly if it is intentionally moved to control populations of A. longifolia other than those present in Portugal. The effects on native biodiversity and ecosystems resulting from invasive populations of A. longifolia are likely to be reduced by the wasp. A. longifolia is grown as an ornamental plant in some EU countries. A. floribunda is not an invasive plant in the EU and is cultivated as an ornamental plant on a small scale in France, Greece and Italy. Any effects on cultivated ornamental A. longifolia and A. floribunda are rated as moderate, although likely to be transient, as the industry could switch to the cultivation of other Acacia spp. For plant species other than A. longifolia and A. floribunda, consequences are expected to be minor, with low uncertainty except for A. retinodes and Cytisus striatus, where further investigation is required. No risk-reducing options in the plant health context are considered necessary, except for monitoring, sentinel planting, and care with regard to quarantine facilities and release protocols to prevent accidental release in situations and locations other than those intended.

Megjegyzések:Following a request from the European Commission, the EFSA Panel on Plant Health (EFSA PLH Panel) was asked to react to a document entitled "Comments on the European Union Food Safety Authority's Pest Risk Assessment for Phyllosticta citricarpa", authored by Hattingh et al., which was posted online in August 2014 on the website of Citrus Research International (Pty) Ltd, South Africa. Citrus black spot (CBS), caused by the fungus Phyllosticta citricarpa (McAlpine) Van der Aa, is a fruit-blemishing and leaf-spotting disease affecting citrus. P. citricarpa is not known to occur in the EU territory and is regulated as a quarantine organism in citrus (Council Directive 2000/29/EC). The Panel assessed the comments by Hattingh et al. in the light of the content of the EFSA PLH Panel Scientific Opinion on CBS and the EFSA report detailing responses to comments received during the public consultation on the draft opinion. The Panel stands by the EFSA PLH Panel Scientific Opinion on CBS and considers that the comments by Hattingh et al. have been thoroughly addressed in the EFSA report on the public consultation on the EFSA PLH Panel Scientific Opinion on CBS. A detailed point by point reply to the comments by Hattingh et al. is provided in an Appendix of this Panel statement. Since September 2014, EFSA has written to the lead author of the comments trying to engage in a scientific dialogue concerning the sources of uncertainty related to the risks posed by P. citricarpa to plant health in the EU, so as to identify ways to reduce such uncertainties (e.g. with further research and/or data exchange). The EFSA PLH Panel also remains open to such constructive dialogue in the future.

Cím:Scientific Opinion on the risk to plant health posed by Xylella fastidiosa in the EU territory, with the identification and evaluation of risk reduction options / Richard Baker; Claude Bragard; David Caffier; Thierry Candresse; Gianni Gilioli; Jean-Claude Grégoire; Holb Imre; Michael John Jeger; Olia Evtimova Karadjova; Christer Magnusson; David Makowski; Charles Manceau; Maria Navajas; Trond Rafoss; Vittorio Rossi; Jan Schans; Gritta Schrader; Gregor Urek; Irene Vloutoglou; Stephan Winter; Wopke van der Werf

Megjegyzések:The EFSA Panel on Plant Health conducted a pest risk assessment and an evaluation of risk reduction options for Xylella fastidiosa. X. fastidiosa has been detected in olive in the EU with a distribution restricted to the region of Apulia in Italy and is under official control. X. fastidiosa has a very broad host range, including many common cultivated and wild plants. All xylem fluid-feeding insects in Europe are considered to be potential vectors. Philaenus spumarius (Hemiptera: Aphrophoridae), a polyphagous spittlebug widespread in the whole risk assessment area, has been identified as a vector in Apulia. The probability of entry of X. fastidiosa from countries where X. fastidiosa is reported is very high with plants for planting and moderate with infectious insect vectors carried with plant commodities or travelling as stowaways. Establishment and spread in the EU is very likely. The consequences are considered to be major because yield losses and other damage would be high and require costly control measures. The systematic use of insecticides for vector control may create environmental impacts. With regard to risk reduction options, strategies for the prevention of introduction and for the containment of outbreaks should focus on the two main pathways (plants for planting and infectious insect vectors) and combine the most effective options in an integrated approach. For plants for planting, these could be pest-free production areas, surveillance, certification, screened greenhouse production, vector control and testing for infection and, for some plant species, treatments (e.g. thermotherapy). To prevent entry of the infectious vectors, insecticide treatments and inspection of consignments and production sites are required. The Panel has also reviewed the effectiveness of risk reduction options for X. fastidiosa and its vectors listed in Directive 2000/29/EC and in the EU emergency measures. The Panel recommends the continuation and intensification of research on the host range, epidemiology and control of the Apulian outbreak.

Cím:Scientific Opinion on pest categorisation of Circulifer haematoceps and C. tenellus / Richard Baker; Claude Bragard; Thierry Candresse; Gianni Gilioli; Jean-Claude Gregoire; Holb Imre; Michael John Jeger; Olia Evtimova Karadjova; Christer Magnusson; David Makowski; Charles Manceau; Maria Navajas; Trond Rafoss; Vittorio Rossi; Jan Schans; Gritta Schrader; Gregor Urek; Irene Vloutoglou; Stephan Winter; Wopke van der Werf

Megjegyzések:The Panel on Plant Health performed a pest categorisation of Circulifer tenellus (Ct) and C. haematoceps (Ch) (Hemiptera, Cicadellidae) for the European Union (EU) territory. They are well?defined insect species that can be identified on the basis of external morphology and male genitalia. Ch and Ct are considered to originate from the Old World; Ct is also present in North America and the Caribbean. In the EU, Ch is reported in 11 Member States, mostly in southern or central Europe, and Ct is reported in Spain, France, Italy and Greece. Neither species is harmful by itself, but they are vectors of Spiroplasma citri, the causal agent of, for example, citrus stubborn disease. The major impact of Ct in North America results from the transmission of Beet curly top virus to sugarbeet. Ct also transmits ♭Candidatus Phytoplasma trifolii' and Ch transmits ♭Ca P. asteris'. There is no transovarial transmission of the pathogens. Ch and Ct are regulated harmful organisms in the EU and listed in Annex II, Part A, Section II, of Council Directive 2000/29/EC together with Spiroplasma citri and with respect to plants of Citrus Fortunella Poncirus and their hybrids, other than fruit and seeds, despite the fact that Ct and Ch have a larger host range. Ch and Ct are likely to be disseminated by plants for planting (the eggs are laid into the leaf veins and petioles), they have also been observed to hitch-hike on terrestrial vehicles, and Ct is known for its very high flight capacity. Both species have many hosts, in particular in the Chenopodiaceae, Brassicaceae and Asteraceae. Ecological conditions in the risk assessment area are suitable for the establishment and spread of S. citri, at least where citrus is currently grown.
