Presented are 202 aphid-host plant associations observed in the Netherlands, including 86 combinations that are new records. These combinations are photographed. Demonstrated is the great diversity of herbs suitable for a number of aphid species to live on. Some of these plants – like Poa annua, Taraxacum officinale, Viola odorata – grow during summer and winter, which gives the aphids an excellent shelter to hibernate. It is observed that during the last years more aphid species hibernate anholocyclically (without eggs), probably due to global warming. Several aphid species are vectors of plant viruses that can be present in host plants like T. officinale and V. odorata. These aphid species are therefore able to infect agricultural crops with viruses early in spring. Furthermore, Sitobion rhamni is in this article recorded new for the Netherlands.
