Short Pest Risk Analysis for Platynota rostrana and Platynota stultana


A short Pest Risk Analysis (PRA) was made for the leaf-roller moths Platynota rostrana and P. stultana following findings of these organisms on imported lots of plants for planting in the Netherlands and in the field in southern Spain, respectively. The PRA does not include a pathwayanalysis but used information on pathways from PRAs made by the United Kingdom and Spain. The PRA assessed the potential impact of P. rostrana and P. stultana for the European Union (EU). P. stultana has been present in Spain for several years and it was assessed that both species can likely establish outdoors in southern parts of the EU. P. stultana can possibly also establish in commercial greenhouses in northern Europe while P. rostrana may not or at much lower population densities. The potential impact of P. rostrana and P. stultana was assessed “Minor” and “Medium” respectively in commercial crops with a medium uncertainty. In tropical greenhouse (e.g. botanical gardens, zoos,…), P. rostrana may have more impact. The potential environmental impact was assessed “Minimal” with medium uncertainty for both species. Risk reduction options were briefly evaluated. Visual inspections of plants for planting and plant products that may carry the species are not considered very effective because low infestation levels can easily be missed. Pesticide applications in the countries of origin can reduce the probability of association but can probably not fully guarantee pest freedom. The requirement of a pest free production place would provide higher safeguards than pest control and visual inspections at the level of commodity but can have a large impact on trade of plants and plant products from areas where the species are present.
