Laboratory of Parasitic Arthropods

Staff Gallery  •  Laboratory Website

The Laboratory for the Study of Parasitic Arthropods originates from the Laboratory of Parasitology, which was created in 1930 on the initiative of the full member of the USSR Academy of Sciences Evgeny Nikanorovich Pavlovsky. The main tasks of the laboratory are the development of fundamental issues of morphology, ecology, systematics and fauna of parasitic and bloodsucking ticks and insects.

In 2010-2020, staff members of the Laboratory for the Study of Parasitic Arthropods revealed peculiarities of the genesis of permanent parasitism and coevolutionary host-parasite relations were established on the basis of different groups of parasitic acarines. Problems of phylogeography of parasites, reversion of the permanent parasitism, significance of horizontal host changes in the evolution of mites, parasites of mammals and birds, were analyzed. The most important aspects of evolutionary plasticity of phytoparasitic arthropods were revealed with the example of gall mites (Eriopyoidea), and new approaches to the study of phytoparasitic systems on the basis of modern molecular methods were elaborated. New data on morphological and taxonomic diversity, phylogeny, and host-parasite relations in main groups of acariform and parasitiform mites and ticks, insects of the flea order, and also bloodsucking blackflies and mosquitoes were obtained. More than 1000 new species and 30 new genera of parasitic arthropods from different continents were described. New type of arthropod silk produced by dermal glands of aquatic mites was discovered and fine structure of the stylostome in mites of the group Parasitengona (Acariformes) was studied in detail. A new phenomenon, penetration of some ixodid tick species, vectors of dangerous diseases, into urban biotopes was discovered and explained, and mechanism, providing accumulation of ticks near pedestrian pathways in city parks, was explained. Mechanisms of formation of long-term life cycles in ticks Ixodes ricinus and I. persulcatus (Acari, Ixodinae) in northwestern Russia were established. An original complex method of the study of thoracic pleurites in bloodsucking mosquitoes (Diptera, Culicidae) was elaborated. In 2010-2020, the results of studies conducted by laboratory staff members were reflected in more than 400 publications.

Laboratory collections

Laboratory for the study of parasitic arthropods keeps one of the largest world collections of parasitic mites, ticks, and insects, including more than 500 thousand samples (collection units). Uniqueness of this collection is determined by the presence of all active developmental stages of all the species of the Northern Palaearctic; at the same time, many species are rather completely represented within the borders of the entire range. First of all, it concerns species with vast ranges, vectors of especially dangerous pathogens. Laboratory collections of ixodid ticks, gamasid and feather mites, bloodsucking mosquitoes, and also biting midges have global significance. The collection was created by several generations of specialists during the entire last century. The world fauna is represented rather completely. Collection includes more than 16 000 slides (about 300 000 determined specimens) and 7000 vessels with material stored in alcohol. The total number of specimens deposited in the collection constitutes more than 1 000 000. At present, the collection comprises the material on the fauna of Russia, Caucasus, Kazakhstan, Middle Asia, Siberia, and the Russian Far East, and also of China, Cuba, Czechoslovakia, Bulgaria, Turkey, and Vietnam. Material of the collection were used for the preparing of the database on the world flea fauna, that was the first of Russian databases was included into the international edition Species 2000 & ITIS Catalogue of Life, uniting monographic databases on different groups of animals and plants within the volume of their world faunas and floras.
