[Academician E. N. Pavlovskiĭ's parasitology school in the Zoological institute RAS].

The first parasitological division in the Zoological Museum was created in 1924 by the initiative of E. N. Pavlovsky and A. A. Schtakelberg and originally had a named "The permanent commission on the study of malaria mosquitoes". In the process of reorganisation of the Zoological Museum into Zoological Institute in 1930, it was modified into the Department of Parasitology with the E. N. Pavlovsky as a head. In 1934-1935, two laboratories were formed within this department: the Laboratory arachno-entomology and Laboratory of parasitic worms. In subsequent history of ZIN, these parasitological laboratories existed at first as subdivisions of the Department of Parasitology and finally the they were reorganised into independent administrative divisions. The study of parasitic and blood-sucking arthropodes is concentrated in the Laboratory of Parasitology (the head Yu. S. Balashov). A creation of the most important concepts of ecological parasitology was taking place in the Zoological Institute in the middle of 30th. E. N. Pavlovsky for the first time had formulated the principle of an organism as an environment for parasites, the concept of communities of parasitic organisms (concept of parasitocoenosis), and the theory of natural focuses of transmissive diseases. In the process of development of these scientific generalisations, a scientific direction named "Academician E. N. Pavlovsky's school of thought in parasitology" was formed in the USSR in 40-50th. In the frame of this school of thought, the main tusks of the Laboratory of Parasitology ZIN are to work out fundamental problems in ecology, systematics and morphology of parasitic and blood-sucking ticks, mites and insects. Within the ecological parasitology, different aspects of host-parasite relationships are studied at organism and population levels. The main basis of systematics studies of parasitic arthropodes is a scientific collection including over 250,000 samples. Based on this material, 40 key books and monographs on the USSR's fauna were created. Over 20 doctors of science and 50 candidates of science have been prepared within the laboratory or under the promotion of its stuff during 70 years of the existence of the Laboratory of Parasitology.
