Acarina 27 (2): 117–144 © Acarina 2019 IN MEMORIAM OF ANDREI VLADIMIROVICH BOCHKOV: SCIENTIFIC BIOGRAPHY Sergey V. Mironov1, Dmitry A. Apanaskevich1,2 and Sergey G.

Oliver, Jr. Institute for Coastal Plain Science, Georgia Southern University, Statesboro, USA Slightly more than a year ago, the world aca- rological and parasitological community suffered from the loss of Andrei (André) Vladimirovich Bochkov (27 August 1968—9 May 2018)—an eminent acarologist, one of the greatest experts on systematics of parasitic acariform mites—as he died on the 50th year of his life, in the prime of his scientific career. Andrei’s death is an irretrievable loss for the national and world science. His col- leagues and friends dedicate this special issue of Acarina to the memory of this outstanding scientist and extraordinary man. The entire 32-year scientific career of Andrei Bochkov was associated with the Zoological Insti- tute of the Russian Academy of Sciences (Saint Petersburg). At this institute, he undertook his long lection and looking after animals in the vivarium. and challenging academic path from Lab Assistant His interest in acarology prompted Andrei to ask to Head Researcher, becoming one of the greatest his supervisor, Dr. H.V.
