EUROPEAN AND MEDITERRANEAN PLANT PROTECTION ORGANIZATION ЕВРОПЕЙСКАЯ И СРЕДИЗЕМНОМОРСКАЯ ОРГАНИЗАЦИЯ ПО КАРАНТИНУ И ЗАЩИТЕ РАСТЕНИЙ ORGANIZATION EUROPEENNE ET MEDITERRANEENNE POUR LA PROTECTION DES PLANTES 05/11896 WPPR point 12.2 Report of a Pest Risk Management: Lymantria mathura This summary presents the conclusions of the pest risk management which has been conducted on the pest, according to EPPO Standard PP 5/4(1) Pest Risk Management Scheme. The text in italics is to guide the assessor as to what information should be presented, it will not appear on the final summary.
IDENTIFICATION OF THE PATHWAYS 1 Pathways studied in the pest risk management Pathway 1: Plants for planting Plants for planting of host trees may carry all stages of the life cycle of the pest on bark and branches. Pathway 2: Cut branches Cut branches of host trees may carry all stages of the life cycle of the pest on them. Pathway 3: Wood with bark Wood with bark of different trees (not only of host species) may carry eggs of the pest. Egg masses are small and well hidden, which makes them difficult to detect. During outbreaks especially, larvae may be associated with wood containing bark and may be hitchhikers on other products. Pathway 4: Packaging, conveyances, containers Other article may carry eggs of the pest in crevasses. Egg masses are small and well hidden, which makes them difficult to detect. During outbreaks especially, larvae may be hitchhikers on various articles. 2 Other pathways L. mathura can naturally spread by flight of adult moths, but the Panel did not consider this case because of a long distance between the actual area of distribution of the pest and the endangered area. It can nevertheless be noted that this pathway may present a risk. IDENTIFICation of POSSIBLE measures for pathways Pathway 1: Plants for planting of deciduous trees originating in countries where Lymantria mathura occurs Measures related to consignments: The following measures have been identified:
Measures related to the crop or to places of production
Pathway 2: Cut branches of deciduous trees originating in countries where Lymantria mathura occurs The risk for cut branches was recognised (because of a very low movement of consignments) as acceptable, consequently no measures have been identified. Pathway 3: Wood with bark originating in countries where Lymantria mathura occurs Measures related to consignments: The following measures have been identified:
Measures related to the crop or to places of production
Pathway 4: Other articles originating in countries where Lymantria mathura occurs Other articles were recognised as acceptable because no appropriate measures have been identified. OTHER POSSIBLE MEASURES Because of the potential for natural spread surveys may be conducted in the areas near to infested areas, using light traps to detect entry of the pest which would be followed by eradication campaigns. Control measures can also be applied in adjoining infested areas, especially during outbreaks, to limit spread. CONCLUSION: SELECTION OF MEASURES
Appendix For each possible category of measures in the pest risk management scheme, this table could identify specifically the ones which were considered suitable ("possible" in bold) and the ones which were not suitable (with a brief justification) The Panel should decide whether such a summary table is useful, and whether it belongs to the pest risk management, or to the report of the pest risk management
