Th is chapter reviews the eff ects of alien terrestrial arthropods on the economy, society and environment in Europe. Many alien insect and mite species cause serious socio-economic hazards as pests of agriculture, horticulture, stored products and forestry. Th ey may also aff ect human or animal health. Surprisingly, there is relatively little information available on the exact yield and fi nancial losses due to alien agricultural and forestry pests in Europe, particularly at continental scale. Several alien species may have a positive impact on the economy, for example parasitoids and predators introduced for the biological control of important pests. Invasive alien arthropods can also cause environmental hazards. Th ey may aff ect native biodiversity through various mechanisms, including herbivory, predation, parasitism, competition for resource and space, or as vectors of diseases. Th ey can also aff ect ecosystem services and processes through cascading eff ects. However, these ecological impacts are poorly studied, particularly in Europe, where only a handful cases have been reported.
