Abstract. The effectiveness of laboratory investigations is not absolute and depends on a number of conditions: the correctness of sampling and preparation of drugs for microscopy, careful transportation and storage, the competence of using laboratory preparations prepared from samples, correct interpretation of these drugs not only attending physician but by the laboratory.

Based on the available literature and own material collected in different parts of the Palearctic a review of the simbiotic invertebrate fauna of Bluethroat – background passerine species in residential habitats has been done. 107 species of free-living and parasitic organisms have been found in the Bluethroats’ body, its feathers and nests. It was noted the presence of abdominal parasites: haemospororida and worms. Some ectoparasites: mites and insects are the hosts and carriers of pathogens of dangerous zoonoses.

Small mammal population structure is analyzed from 1959 to 2014 in the south of the Central Chernozem region. Zoologists of sanitaryepidemiological service conducted work within the epidemiological monitoring. Small mammals were caught by mousetrap «Gero» and traps. It was found that in the south of the Central Chernozem aquatic habitats inhabited by mammals for more than 25 species, mostly rodents (Rodentia). Registered insectivores (Eulipotyphla) and prey (Carnivora). Water vole (Arvicola amphibius) prevailed until the 70s of the last century as a result of trapping traps. The proportion of this species was more on the Oka-Don lowland plain than on the Middle-Russian upland. Field mouse (Apodemus agrarius) and forest mouse (Ap. (S.) uralensis), grey voles (Microtus) and bank voles (Myodes (C.) glareolus) accounted for 75% of the individuals during the trapping traps «Gero». On Middle-Russian upland the main population animals were forest mice, on the Oka-Don plain – field mouse. Compared with the second half of the last century changed the modern population structure of small mammals: in the last two decades on the Oka-Don lowland plain dominated field mice and grey voles and on Middle-Russian upland forest and field mice, bank voles. Small mammals of riparian habitats are also present in open, meadow-field and forest-bush habitats, stacks and ricks, in urban and rural buildings. The pathogens of hemorrhagic fever with renal syndrome, tularemia and leptospirosis are circulating among small mammals. In riparian habitats distributed combined natural foci of these infections. Against the background of changes in the structure of small mammals population participation of individual species of rodents in the epizootic process has changed too.

The threat of proliferation of the black widow spider Latrodectus tredecimguttatus in the city of Taganrog (Russia)

entomologist Branch FBUZ «Center of hygiene and epidemiology in RO in Taganrog», Russia, 347930, Taganrog, Bolshoi prospect, 16
The entomological interest of specialists and medical services of the city of Taganrog to the widow arose in 2003 after registering of a resident’s severe toxic poisoning as the result of the bite of a spider, and discovering the high number of widow spiders in urban areas. Since that moment, the necessity to explore the settlement of the widow in the urban area and development of methods of struggle with them emerged to protect the inhabitants from the poisonous bites. In 2013-2015 research has shown the expansion of the territory inhabited by the widow.

A comparison of the dynamics of damage and death under exposed toxic baits on cockroaches Blattella germanica 12 multiresistant strains from Moscow, Obninsk and Ekaterinburg in comparison with laboratory-sensitive S-NIID strain has been carried out. High sensitivity of resistant insects to baits on the basis of boric acid and liquid hydramethylnon has been shown. It was found repellent effect of dry baits on the basis of boric acid. Indicators of resistance for all strains to liquid baits on the basis of boric acid were similar for males and fluctuated in the range 0.7-1.4 and 0.7-1.6 for females. Cockroach’ sensitivity to baits on the basis of hydramethylnon was the same in all races – resistance rates were – 1.0-1.2 0.7-1.1 for males and – 0,7-1,1 for females.
