A review of grass flies (Diptera, Chloropidae) of Karelia and Murmansk Province of Russia

One hundred and sixteen species of Chloropidae (Diptera) are recorded in Russian Karelia and Murmansk Province: 112 in Karelia and 44 in Murmansk Province. Twenty-two and seven species are new for Karelia and Murmansk Province, respectively. Calamoncosis oscinella is for the first time reported from Russia and Elachiptera breviscutellata - from European Russia. Pseudogaurax venustus is reinstated as Gaurax venustus. Taxonomic notes are provided on Eribolus nana, Polyodaspis ruficornis, Oscinella vindicata and Cetema simile. The distribution and biological data are given for every species. Point maps are provided for species with at least one exactly known location. The zoogeographical structure of Chloropidae fauna on the examined territories is briefly discussed and compared with other north-European countries.

Polar Experiment Station of VIR: the northernmost outpost of potato research

The establishment and progress of potato cultivation in the Kola Peninsula are closely associated with the Polar Experiment Station of the N.I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR). The data are presented on the development of early-ripening and high-yielding potato cultivars based on the source material from the VIR collection: ‘Imandra’, ‘Sestra Imandry’, ‘Murmansky’, ‘Snezhinka No. 3’, ‘Khibinsky ranny’, etc. Prominent breeders and scientists, who worked at different times at the Polar Station, contributed to the release of unique early-ripening potato cultivars: J. H. Eichfeld, M. N. Veselovskaya, I. A. Veselovsky, F. I. Manykov, M. A. Vavilova, N. N. Ivanova, L. A. Dremlyug, A. M. Kozeletskaya, S. A. Anikina, G. D. Melnichuk, etc. Some of the cultivars developed from 1937 to 1968 are still used in large-scale potato production in Murmansk Province. Every year the cultivar and species diversity of potatoes is planted in the fields of the Arctic North. Today, the extensive material from the potato collection makes it possible to study the impact of environmental factors, identify sources of earliness and productivity, and conduct breeding activities aimed at the release of early cultivars.

The aphid fauna (Hemiptera, Sternorrhyncha, Aphidomorpha) of Murmansk province (Russia), with description of Aphis khrulevi sp. nov. and Dysaphis karyakini sp. nov. and males of Chaitophorus nigricantis Pintera, 1987

An updated aphid (Hemiptera, Aphidomorpha) check-list of Murmansk province (European Russia) is presented, it includes 162 species. Chaitophorus nigricantis Pintera, 1987, Schizaphis nigerrima (Hille Ris Lambers), Hyperomyzus (Neonasonovia) zirnitsi Hille Ris Lambers, Nasonovia (Kakimia) vannesii Stenseth, Plocamaphis flocculosa goernitzi Börner and Schizaphis graminum gigjai Stroyan are recorded for the first time from Russia. Both apterous and alate males of Chaitophorus nigricantis nigricantis Pintera are described. Two new aphid species are described: Aphis khrulevi sp. nov. from fundatrices and apterous viviparous females, living on Veronica longifolia and Dysaphis karyakini sp. nov. from apterous and alate viviparous females, oviparous females and males, living on Cenolophium denudatum. Comments about the distribution and biology of aphids in this Northern part of Europe, and on the completeness of the list are given.
