The purpose of the study. Research objective is to perform differentiation between enzootic as regards HFRS territories in Ufa, depending upon the level of potential epidemic threat, applying photogrammetric processing of satellite images. Materials and methods. The data on ecological-epidemiological monitoring over HFRS foci, collected at the premises of the Republican Center for disinfection over the period of 2008-2014, has served as the tool for evaluation of epidemiological significance of various urban landscape elements discerned in the satellite imagery. Among them are residential areas, forest-parklands, and natural objects. Research findings. Specified are the basic indicating decrypting properties of the territories characterized by different level of potential epidemic hazard, in particular: high, medium, and low. It is demonstrated that the determining factor of high potential epidemic threat, attributed to the focal territories of Ufa, as regards HFRS is the size of the areas of adjoined residential, forest-parkland, and natural landscapes. Conclusions: Application of the earth remote probing for epidemiological zoning of enzootic as regards HFRS territories of Ufa opens the prospect for early planning of the preventive measures in the regions marked by the high risk of exposure to the infection.

Keywords: HFRS foci on the territory of Ufa; epidemiological hazard level of the territory; methods of the earth remote probing; ecological-epidemiological indicators; urban residential, forest-parkland, and natural landscapes; morbidity rate; anti-epidemic measures.

The results of observations of the state of small mammals populations in 2013–2015 are considered. The special role of water voles as the main host and the mass source of tularemia infection at the confluence of Ob and Irtysh rivers in 2013 and restructuring zoocenosis in subsequent years are noted.

Keywords: Khanty-Mansiyskiy Avtonomnyy Okrug – Yugra, small mammals, tularemia.

Synanthropic rodents and the forms of Synanthropism

V. V. Kucheruk (Translation of the first part of the article: Kucheruk V.V. Synanthropic Rodents and their Significance in the Transmission of Infections // Theoretical questions of natural foci of diseases / Proceedings of a Symposium held in Prague November 26-29, 1963. Prague 1965. P. 353-366. – with amendments. From the archives V. V. Kucheruk)

Animals, classified as synanthropic, are the species that regularly inhabit the territory of the settlements or human constructions (various buildings, residential buildings, shops, places of storage of food, and so on. P.), forming there permanent or periodically appearing independent or semidependent populations. In order of decreasing the connection level with human it’s proposed to distinguish 6 forms of synanthropism. The highest form – the obligate synanthropism is absent in rodents. With increasing the level of urbanization the share of true sinantrops (house mice, brown and less frequently black rats) is increasing. They have settled with the man far beyond their original areas. Rodents, which is inherent in geographic and environmental limited synanthropism are closely related to man, but only in some regions. Many species inhabit within the boundaries of settlements mainly in undeveloped areas, entering the buildings (environmental limited synanthropism) or basically without entering them (outside buildings synanthropism). Finally, some rodents can not exist without relation to natural habitats (false synanthropism).

It has been reviewed some modern preventive measures aimed at protecting museum collections from damage by insects and also summarized practical experience in applying of repellents, pheromone and adhesive traps under storages and expositions conditions.

The insecticide baits against cockroaches based on isoxazoline group (fluralaner and afoxolaner) and spinosyn group (spinosad) were tested. It was found that isoxazolines baits were highly toxic to cockroaches. The effective dose of afoxolaner is 0.21 and 1.20, fluralaner – 1.40 and 5.90, spinosad – 26 and 180 mg a.i./ individual (male and female SNIID strain, respectively). German cockroaches from RM1-strain respond to bait based on isoxazolines or spinosyn with slowing symptoms of poisoning and reduction in deaths compared with SNIID. Tolerance to these compounds ranged from 2,2× to 4,7. It is expected that the increased level of monooxygenases in resistant cockroaches can affect their tolerance to the isoxazolines and spinosad.

To control the pharaoh’s and common black (garden) ants it was offered a new domestic means on the basis of chlorpyrifos (0.5%) in the form of loose granules of different bright (blue, brown, orange or purple) colors, odorless, soluble in water. The presence of more than 50% of food attractants (honey, glucose syrup, peanut oil, and others.) caused an interest in insects to the granules, which further leads to their death.
