Spodoptera species (armyworms) belong to the Noctuidae. The larvae cause damage by consuming plant parts. Currently, four Spodoptera species are regulated in the European Union, S. eridania, S. frugiperda, S. litura and S. littoralis of which the first two species are present in the Americas. However, many more Spodoptera species which may be a threat to plant health in the EU. The reason for performing he present study is the interceptions of several non-regulated Spodoptera species in the Netherlands on plants and plant products originating in the Americas. The study assesses the potential impact of the different Spodoptera species that are present in the Americas. For those species that are considered of economic importance for the EU, a full Pest Risk Analysis, including a pathway-analysis, a more detailed assessment of the endangered area and an evaluation of risk reduction options could be conducted at a later stage.
