Diversity of plague vectors: fleas of the genus Neopsylla Wagner, 1903 (Siphonaptera, Hystrichopsyllidae). P. 179-203.
Taxonomic diversity and peculiarities of distribution and host-parasite relations of fleas of the Holarctic-Indo-Malay genus Neopsylla (Hystrichopsyllidae, Neopsyllinae) are analyzed in the present review. The role of separate representatives of this genus as pathogen vectors and reservoirs in natural plague foci of Eurasia is observed. It is demonstrated that 14 out of 67 flea species of the genus Neopsylla are marked as main, secondary, or occasional vectors of this infection.
in RussianThe multi-year monitoring of the tick-pathogen system in natural foci of tick-borne encephalitis in Irkutsk suburbs. P. 204-225.
During 15 seasons (2005-2019) monitoring of natural tick-borne encephalitis (TBE) foci state was held on several key plots of the popular recreational and touristic way Irkutsk-Baikal along the road 25K-011. The evidence of stable state of viral and vector populations was provided. High degree of diversity of the investigated plots by level of Ixodes persulcatus imago numbers and peculiarities of its multi-year and seasonal dynamics was shown. Spatial and temporal differences in ticks infection rate as well as lack of trend for the infection rate change during the observed period. The lack of correlation between multi-year abundance of the vector and its infection rate was found. The significant role of the taiga tick males in dissemination of the TBE virus has been highlighted.
in RussianAnalysis of findings and host-parasite relations of the tick Ixodes trianguliceps Birula, 1895 (Ixodidae, Ixodinae) in Northwestern Russia and in neighboring European countries. P. 226-237.
The review summarizes and analyzes the literary data on the distribution and hostparasite relations of the tick Ixodes trianguliceps Birula, 1895 (Ixodidae) in Northwestern Russia and in the adjacent European countries. The factors influencing the number of ticks and the coincidence of their distribution with the habitat of the main and additional hosts are discussed.
in RussianMorphological features of pregenital and genital segments of male horseflies (Diptera, Tabanidae) of the Hybomitra (s. str.) bimaculata Macq. groups. P. 238-260.
The terminalia of male horseflies (Diptera, Tabanidae) of the Hybomitra (s. str.) bimaculata Macq. group, including Hybomitra (s. str.) bimaculata Macq.: Hybomitra lurida (Fallén, 1817), H. nitidifrons confiformis (Chvala et Moucha, 1971), H. bimaculata (Macquart, 1826), H. muehlfeldi (Brauer, 1880), H. distinguenda distinguenda (Verrall, 1909), H. lundbecki lundbecki (Lyneborg, 1959), H. ciureai (Séguy, 1937), H. nigricornis (Zetterstedt, 1842) and H. montana montana (Meigen, 1820) are described. The differences in the ratio of linear sizes of hypandria, epandria, and cerci are analyzed using the Mann-Whitney U-test. Differences in the structure of male terminalia of the species were revealed and a table for determination of males of Hybomitra (s. str.) bimaculata Macq. group is assumed on the basis of these differences.
