The whiteflies of The Netherlands, including two species new for the Dutch fauna (Hemiptera: Aleyrodidae)

An annotated list is given of whitefly species of the Netherlands, occurring in the open, indoors in greenhouses and living rooms and those intercepted during import inspections. In this paper over 50 species are mentioned, 14 of which occur in the open, 6 species have been only found in greenhouses and 42 species have been intercepted during quarantine inspections. The majority of the observations stem from the period 1970-2010. Aleurotuba jelinekii and Siphoninus immaculatus are new for the Netherlands, occurring outdoors. Due to regular introductions of species living on traded plants the chance that new species will establish is enhancing.
