Prerequisites for the formation of combined natural foci of Puumala and Kurkino hantoviruses in the forest-steppe and forest landscape zones of the Republic of Bashkortostan are discussed in the paper. In 2021, for the first time ever, the RNA of Dobrava-Belgrade (allegedly Kurkino) hantavirus was detected in Birsky, Blagoveshchensky, Gafuriysky, Ishimbaisky, Krasnokamsky, Chishminsky administrative districts, Ufa and Oktyabrsky cities applying PCR assay. Kurkino hantavirus was registered in samples of field material from field, small forest, yellow-throated mice; common, bank voles and root voles. An assessment of the HFRS incidence dynamics in the Republic of Bashkortostan in 2010–2021 has been conducted. A strong positive correlation (R=0.89) between the annual incidence of HFRS and the number of infected bank voles in the autumn period of 2010–2021 has been established. The factors that determine the high incidence of HFRS among the rural and urban population of the Republic of Bashkortostan in the modern period are considered. The need for further research to confirm the existence of combined natural foci of Puumala and Kurkino hantoviruses in the Republic of Bashkortostan is highlighted.

Generalized maps are presented on the distribution of the 100 most dangerous invasive species (TOP-100) in Russia, including a wide range of organisms: from bacteria to mammals. Assessment of the species richness of invasive species from the TOP-100 list are presented for each administrative-territorial subject of the Russian Federation using modern GIS technologies. The created maps represent the hot zones of influence of dangerous marine, freshwater and terrestrial species on the natural ecosystems of Russia. It is shown that the largest number of the most dangerous invasive species (more than half, maximum 64% of the total) occurs in the Leningrad region and in the western regions of the Southern Federal District.

Kalinina I.A. 1

1 The State Hermitage Museum, Saint Petersburg 190000, Russian Federation

The article is devoted to the problem of protecting museum collections from insects. A review of the types of traps used in museums for detecting, monitoring and studying the biology of insects has been carried out. The experience of using glue and pheromone traps in museums has been studied. The characteristic of features of work with different types of traps is given. Considerable attention is paid to the specifics of working with traps based on the experience of the Laboratory for Biological Control and Protection of the State.

Keywords: insects, monitoring, museums, glue and pheromone traps

The possibilities of using chromatographic methods (HPLC and GC) in the determination of complex multicomponent mixtures of insecticidal substances in model solutions and some commercial compositions used as active substances in products used in the practice of «pest control» are considered. The aspects of control in the initial substances, means and working solutions based on them, the air of the working area are considered. The features of the choice of an analytical method (chromatographic or spectrophotometric), the implementation of sample preparation in conjunction with the choice of an available chromatographic method are given. The possibilities and limits of group determination by chromatographic methods are examined on model solutions. Adapted schemes of analysis by the method of HPLC in isocratic mode using minimal hardware design and the least toxic mobile phases based on acetonitrile are proposed. For some products, the isomeric composition was identified with the identification of the most active isomer (group of isomers).
