Extract
1. The Viburnum aphis, Aphis (Doralis) viburni, Scop., is described and compared with two other species, A. fabae, Scop., and Ceruraphis eriophori, Wlk., also found on Viburnum opulus.
2. Transference experiments show that colonies can be established artificially on Euonymus europaeus and Rumex obtusifolius, but not on other common host plants of A. fabae.
3. The sexupara is apterous and produces mixed colonies, thus differing from A. fabae where an alate gynopara produces only oviparae, the males arising from an apterous mother on the summer host.
