We report records of 25 species of aphids collected from four species of woody plants (Pinus sylvestris, Picea abies, Betula pubescens and B. pendula) at 50 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 obvious limitations of our survey, the obtained information substantially contributed to the knowledge of the distribution of aphids in North European Russia, including Murmansk oblast (103 species recorded to date), Republic of Karelia (58 species), Arkhangelsk oblast (37 species), Vologda oblast (17 species) and Republic of Komi (29 species). We confirm the occurrence of Cinara nigritergi in Southern Karelia; Pineus cembrae, Cinara pilosa and Monaphis antennata are for the first time recorded in Norway.

First Time

A diagnosis of European Phrudinae is given and a key is presented for Seleucus cuneiformis Holmgren and eleven European species of Phrudinae. Seleucini Vikberg trib. nov. in Ctenopelmatinae is proposed for Seleucus Holmgren. Astrenis nigrifacies Vikberg sp. nov. (Finland, Sweden, England, Scotland, France), A. brunneofacies Vikberg sp. nov. (Finland, Sweden, England, Scotland, Germany, Italy), Phrudus compressus Vikberg sp. nov. (Finland, Sweden) and the males of A. paradoxus (Schmiedeknecht) and P. badensis Hilpert are described for the first time. All other species are redescribed, and new distributional data are reported. The dentation of the claws and the form and location of modified sensory structures on the subbasal flagellomeres are used as taxonomic characters. Pygmaeolus nitidus (Bridgman), Astrenis nigrifacies, A. brunneofacies, Phrudus defectus Stelfox, P. compressus and P. badensis were found to be associated with ageing logs of Pinus sylvestris L. and Picea abies (L.) H. Karst.

Abstract Selected forestry parameters were investigated in the system of tree vegetation and wood-destroying fungi in parks of the Kyiv city along a gradient of recreational transformation. We investigated vitality, age structure and health conditions of woody plants (Acer platanoides L., Aesculus hippocastanum L., Carpinus betulus L., Frangula alnus Mill., Pinus sylvestris L., Quercus robur L., Q. rubra L., Sambucus nigra L., Tilia cordata Mill.), and species, systematic, trophic and spatial compositions of xylotrophic fungi (27 species of xylotrophs representing 22 genera, 16 families, 6 orders of divisions Basidiomycota; class Agaricomycetes). The results showed that the communities of tree vegetation and xylotrophic fungi in parks depend on the degree of recreational transformation of the environment. Vitality, age structure and health conditions of trees altered species composition of xylotrophs.
