The present Quickscan was conducted after the finding of a new thrips species for Europe, Thrips setosus, in the Netherlands. The species originates in Eastern Asia. It is not known how the species entered the Netherlands and how long it had already been present before it was detected. The species is polyphagous and both outdoor and greenhouses conditions in the Netherlands are likely suitable for establishment. T. setosus has been described as a minor pest in Japan. The species may, however, cause significant damage on certain crops. The Hydrangea plants on which the species was found were for example heavily infested and the species can act as a vector of Tomato spotted wilt virus.
