Resistance of Norway rat to anticoagulant rodenticides now occurs in many countries in Europe, America and Asia. Resistance is often associated with single nucleotide polymorphisms (SNPs) in the VKORC1 gene. This study gives a first overview of the distribution and frequency of VKORC1 SNPs in Norway rat, based on tissue samples from several cities in Russia. No SNPs associated with resistance were found in Kostroma and Chita. We found one of the several previously described mutations Tyr139Ser for VKORC1. This mutation is known to be associated with resistance to anticoagulant rodenticides, and it was found in 29% of the samples from Moscow. All this rats were heterozygous for the Tyr139Ser variant.

For 6 years (2013-2018), in order to protect lawns and flowerbeds from damage by Talpa europaea LINNAEUS, 1758, moles were trapped in Pavlovsky Park (St. Petersburg, 59°41'37'' nl. 30°27'19''el.) A ratio of the trapping area to the total park area 1:60. From 11 ha territory a total of 21 to 86 individuals per year were caught. Breeding season, depending on the conditions of the year, lasted from April to July (usually with a maximum in May). In some years, cases of late catching of breeding individuals were recorded (at the end of August and in October). The territories, cleaned from moles, were re-occupied. Even after the beginning of dispersal of young animals, males prevailed in catches, the share of females ranged from 15% to 38%. Catching rates were usually higher in years with a wet and cool growing season: the correlation coefficient of the total number of individuals caught during the year with hydrothermal coefficient for May – September is r = 0.77. A more intensive elimination of breeding individuals in April-May negatively correlated with the total catch of the following year (r = -0.86). Trapping of moles from limited territories, reduces the total resource of the population due to migration. The perspective for the rest of population is in selective elimination of individuals, preserving more females.

The authors in their article analyze samples taken from various environmental objects (water, soil, washouts from hard surfaces, food products), studied in parasitological units of the sanitary service of the Astrakhan region. So, in 2019, 13,237 samples were studied (14,930 studies were conducted), taken from environmental objects, of which 68 samples did not meet hygiene standards. The invasion rate was 0.5%.

Based on the materials of the bacteriological and parasitological research laboratory of the Federal State Health Institution “Center for Hygiene and Epidemiology in the Astrakhan Region, the epidemiological situation of ascariasis in children in the Astrakhan region for 2015–2019 is analyzed. It has been established that despite the anti-epidemic measures carried out in the region, ascariasis continues to be an urgent problem among adults and children. In most cases, ascariasis was detected in preschool children, which may be due to noncompliance with personal hygiene rules and eating unwashed fruits and vegetables contaminated with roundworm eggs. With ascariasis, children the most often complain of poor appetite and pain in the epigastric region. The presence of unfertilized Ascaris lumbricoides eggs in feces indicates the presence of only female parasites in the host organism (male is absent).

The target efficacy of two new insecticidal preparations containing acetamipride in combination with compounds from the group of pyrethroids as the active substance was studied. An acute effect has been established for cockroaches, ants, bedbugs, flies and recommendations are given for practical use in the field of medical pest control and by the population in everyday life
