Investigation of Eriosomatidae in Belarus started in the 1900s. However, a regional checklist of Eriosomatidae aphids was not published till now. Based on material preserved in the collections of Belarusian State University and the Zoological Institute of the Russian Academy of Sciences, and data scattered across publications we have compiled the first comprehensive list of Eriosomatidae recorded from Belarus and briefly analysed it from the geographical and ecological points of views. The list includes 12 genera and 27 species. Pemphigus passeki Börner, 1952 has been recorded from Belarus for the first time. The registered diversity is less abundant than in the adjacent Poland. In the accordance with the global pattern of aphids host plant connections, a single species permanently inhabit woody plants (monoecious species), the other ones are dioecious and migrate from woody plants to woody (eight species) or herbaceous (12 species) plants. Four species is anholocyclic.

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.

ОЦЕНКА ВРЕДОНОСНОСТИ КАШТАНОВОЙ МИНИРУЮЩЕЙ МОЛИ-ИНВАЗИВНОГО ВРЕДИТЕЛЯ ЗЕЛЕНЫХ НАСАЖДЕНИЙ БЕЛАРУСИ Аннотация. Основной вредитель декоративных посадок конского каштана обыкновенного (Aesculus hippocastanum L.).-каштановая минирующая моль, или охридский минер (Cameraria ohridella Deschka & Dimič, 1986), чужеродный для фауны Беларуси инвазивный вид минирующих фитофагов. Ежегодно наблюдаемые вспышки массового размножения C. ohridella ведут к утрате кронами естественного внешнего вида и ранней дефолиации, что катастрофически сказывается на декоративных и рекреационных качествах зеленых зон. На основании данных многолетних исследований (2013-2019 гг.) дана количественная оценка физиологической вредоспособности, экологической обусловленной и общей вредоносности каштановой минирующей моли во всех 5 районах интродукции древесных растений в Беларуси. Значения показателей физиологической вредоспособности и общей вредоносности были минимальны для Северного и максимальны для Южного района интродукции древесных растений, статистически достоверно различаясь для большинства дендролого-интродукционных районов.

A morphological analysis of extensive material from Belarus (45 localities, 117 samples, 2002Belarus (45 localities, 117 samples, -2010 confirms that Macrosiphum silvaticum Meier, 1985 is a junior synonym of Macrosiphum knautiae Holman, 1972. Two species of the genus Macrosiphum were found on Knautia arvensis in Belarus in 2002-2010: M. rosae (Linnaeus, 1758), and M. knautiae Holman, 1972, the latter species being predominant. In addition to common key characters, a canonical discrimination function (Rakauskas 2003) is necessary to ensure exact morphological discrimination between the two species. 2002-2010 m. Baltarusijoje keturiasdešimt penkiose vietovėse surinktų 117 amarų mėginių morfologinė analizė patvirtino, jog amarų rūšies pavadinimas Macrosiphum silvaticum Meier, 1985 yra jaunesnysis pavadinimo Macrosiphum knautiae Holman, 1972 sinonimas. Tyrimų metu Baltarusijoje ant Knautia arvensis aptiktos dvi Macrosiphum genties amarų rūšys: M. rosae (Linnaeus, 1758) ir M. knautiae Holman, 1972, pastaroji rūšis randama dažniausiai. Norint atskirti šias dvi rūšis, be įprastinių apibūdinimo raktuose taikomų morfologinių požymių reikia naudoti dar ir kanoninę atskyrimo funkciją (Rakauskas 2003).

The walnut leaf miner Caloptilia roscipennella (Hübner, 1796) is recorded for the first time in Belarus. The larvae of this species damage leaves of the common walnut (Juglans regia L.). In 2015, C. roscipennella was registered in a number of geographical locations in the Brest and Gomel provinces. In subsequent years, the species was found only in the same places. It is shown that the name C. roseipennella Anikin, Zolotukhin et Kirichenko, 2016, syn. nov., being an unjustified emendation, is a junior synonym of C. roscipennella (Hübner, 1796) in accordance with the International Code of Zoological Nomenclature, Articles 32.5.1 and 33.2.3.
