V.2012: Distribution records of aphids (He- miptera: Phylloxeroidea, Aphidoidea) associated with main forest-forming trees in Northern Europe. — Entomol. Fennica 23: 206–214. We report records of 25 species of aphids collected from four species of woody plants (Pinus sylvestris, Picea abies, Betula pubescens and B. pendula)at50 study sites in Northern Europe, located from 59° to 70° N and from 10° to 60° E. Critical evaluation of earlier publications demonstrated that in spite of the obvi- ous limitations of our survey, the obtained information substantially contributed to the knowledge of the distribution of aphids in North European Russia, includ- ing Murmansk oblast (103 species recorded to date), Republic of Karelia (58 spe- cies), Arkhangelsk oblast (37 species), Vologda oblast (17 species) and Republic of Komi (29 species). We confirm the occurrence of Cinara nigritergi in South- ern Karelia; Pineus cembrae, Cinara pilosa and Monaphis antennata are for the first time recorded in Norway. A.
