SOSNOVSKY HOGWEED (HERACLEUM SOSNOWSKYI MANDEN., APIACEAE) IN BASHKORTOSTAN - Abramova  L.M.,  Golovanov  Ya.M.,  Rogozhnikova  D.R.  - Heracleum sosnowskyi Manden in the Republic of Bashkortostan is distributed mainly in the northern and central Ural piedmont, a total of 20 localities are known. Upon naturalization, the species becomes the dominant and forms the communities of the association of Urtico dioicae–Heracleetum sosnowskyi. In 2016–2019 5 cenopopulations of H. sosnowskyi were investigated in the Krasnokamsky, Tatyshlinsky and Yanaulsky districts of Bashkortostan. The total density of the species in cenopopulations is high and amounts to 41–92 individuals/m², the effective one (density of generative individuals) is 1.9–3.4 individuals/m², while biomass can reach 2.3–4.6 kg/m². The proportion of the species in the community is high – 77.8–96.8%. According to most indicators of both vegetative and generative spheres, the cenopopulation located near the village of Tashkinovo leads, while the minimum values for all parameters are noted in the cenopopulation near the village of Razdolye in the Krasnokamsky district of the Republic of Bashkortostan. H. sosnowskyi poses a serious threat to the biodiversity of the ecosystems of the Republic of Bashkortostan.

FEATURES OF THE SPATIAL DISTRIBUTION OF INVASIVE SPECIES OF AMPHIPODS IN THE LITTORAL OF LAKE LADOGA - Barbashova  M.A.,  Trifonova  M.S.,  Kurashov  E.A.  -The modern distribution of invasive amphipods of Baikal (Gmelinoides fasciatus (Stebbing, 1899), Micruropus possolskii Sowinsky, 1915) and Ponto-Caspian origin (Pontogammarus robustoides Sars, 1894, Chelicorophium curvispinum (Sars, 1895)) in Lake Ladoga was shown. The heterogeneity of the distribution of quantitative indicators of amphipods in different parts of the lake was established. The most widespread species in the littoral zone was G. fasciatus. A decrease in the contribution of G. fasciatus in the bottom communities of macrozoobenthos was noted. The dominant role of G. fasciatus was observed only in those parts of the lake where other species of invasive amphipods did not penetrated yet. The habitat of Ponto-Caspian amphipods is limited by the boundaries of the Volkhov Bay. A significant increase in the quantitative development of P. robustoides and active dispersal of M. possolskii to the South along the west coast of the lake indicate the ongoing structural restructuring of littoral biocenoses.

ECOLOGY AND DISTRIBUTION OF INVASIVE MOSQUITO SPECIES AEDES ALBOPICTUS (SKUSE, 1895) IN THE SOUTH OF EUROPEAN PART OF RUSSIA - Bega  A.G.,  Moskaev  A.V.,  Gordeev  M.I.  -The aim of the study was to show ecological preferences and to establish the actual range of the invasive mosquito species Aedes albopictus. The moving of Ae. albopictus from the Black Sea coast of the Caucasus into the interior of the European part of Russia for the period 2017–2019 is shown. The northern border of the distribution of this species in 2019 passed through the cities: Timashevsk, Kropotkin, and Armavir. The limiting environmental parameters for the preimaginal stages of Ae. albopictus development are: the content of oxygen dissolved in the water and the water acidity. We believe that the air humidity and the floristic composition of the territory are the main factors determining the movement of the Aedes albopictus mosquitoes deep into the Russian Plain. The data obtained can be used for epidemiological surveillance and planning of preventive measures.

DISTRIBUTION OF INVASIVE SPECIES PROSOPIS JULIFLORA (MIMOSACEAE) IN FUJAIRA (UAE) - Byalt  V.V.,  Korshunov  M.V.  - The article analyzes the secondary area in the Emirate of Fujairah, as well as the peculiarities of seed dispersing, seed germination and early seedling development of Mesquite, or Prosopis juliflora – the alien species of Mimosaceae, which appeared on the territory of the Emirates in the twentieth century, and one of the first collected herbarium specimen is dated 1983. In the secondary area most often, the Mesquite is found in anthropogenic habitats: in gardens, as well as near roads, on waste grounds, less frequent on the streets of settlements, garden fences etc. In regions represented by herbarium collections, P. juliflora is successfully naturalized and creates stable self-sustaining populations. It has a complex of specific helio-mesomorphic features that allow it to take root successfully in relatively open moderately wet, and even dry or saline habitats and compete with native species of acacia (Acacia tortilis, A. ehrenbergii) and local prosopis (P. cineraria). Characteristics such as good germination, significant morphological, dimensional and temporal variability of premature individuals of P. juliflora, identified in this work, undoubtedly contribute to the successful naturalization of the species in the secondary range and its wide distribution throughout the Emirate. Due to the high aggressiveness of Mesquite, it is necessary to develop a method of dealing with this plant in the UAE, which will stop its uncontrolled settlement in the region. We have compiled a map of Mesquite distribution in Fujairah and surrounding areas, which clearly shows the scale of the disaster. A method for assessing invasion on a five-level scale based on reproductive success has been developed and applied. The structure of ecotopes at an early and middle stage of penetration of P. juliflora was analyzed using large wastelands (2 and 1.2 ha) in the village Mirbah and the city of Fujairah on the coast of the Gulf of Oman.

GENETIC METHODS OF INSECT CONTROL. HISTORY AND CURRENT STATE - Viktorov  A.G. -The review considers the main stages in the development of genetic method of insect control: 1) The idea of A.S. Serebrovsky, who suggested releasing males with non-viable translocations into nature; 2) "Z-lethal" method of V.A. Strunnikov for control of harmful Lepidoptera, which consists in the release of males carrying two non-allelic recessive mutations in the sex Z-chromosomes into nature; 3) Sterile insect technique (SIT) used widely in practice in the second half of the XX-th century;  4) Genetically engineered biotechnology RIDL (Release of Insects carrying a Dominant Lethal) used in practice to control the invasive mosquito Aedes aegypti, the vector of Zika viruses and yellow fever. It is generalized that the main opponent of the genetic method of insect control is natural selection, which supports females, choosing natural rather than sterile or "genetically modified" males on mating. It follows from the above that genetic methods of control can be effective only in control of invasive species have not spread widely yet.

ANALYSIS OF DISTRIBUTION OF STRIPED SEABREAM (LITHOGNATHUS MORMYRUS L., 1758) (ACTINOPTERYGII: SPARIDAE) IN THE BLACK SEA  - Guskov  G.E. - Information on the distribution of the mormor (striped seabream) Lithognathus mormyrus moved into the Black Sea is summarized on the basis of literature, own and survey data. The chronology and geographical coordinates of the finds of the alien species for the recent 40 years (1980–2020) are given.

INVASION OF ZEBRA MUSSEL DREISSENA POLYMORPHA (PALLAS, 1771) IN THE BASIN OF LADOGA LAKE AND THE BIOCHEMICAL ROLE OF THE INVADER - Dudakova  D.S.,  Svetov  S.A.  -In June 2017 in one of the career in the basin of Lake Ladoga (Kakolowski career, Kirovskiy district, Leningrad oblast), a stable population of Dreissena polymorpha was found. The biological observation and study of microelement composition of the shells of Dreissena p. were conducted. It was revealed that the population referred to young one with high potential for further development under favorable environmental conditions. The latter is expressed by the relatively high mineralization of the water reservoir, which provides the optimal level of necessary elements for the construction of the calcareous skeleton of a large number of individuals. The main chorological types formed here were dreissen-brushes and druses, allowing the fullest use of resources in a limited space. The participation of shells in the accumulation and bio-burial of a number of trace elements is shown.

THE EXPANSION OF THE BIVALVE ANADARA KAGOSHIMENSIS (TOKUNAGA, 1906)  IN THE SEA OF AZOV -Zhivoglyadova  L.A.,  Revkov  N.K.,  Frolenko  L.N.,  Afanasyev  D.F.- The dispersion of the Asian bivalve Anadara kagoshimensis in the Sea of Azov continues for more than 30 years. The study of the expansion of A. kagoshimensis is based on the materials of annual bottom grab surveys performed in the Sea of Azov in 1989–2018. The process of dispersion of the mollusk is considered through the changes of the range area, the indicators of abundance (specific abundance, biomass, total stock) and the structure of the population. The main stages of the invasion process are highlighted and discussed. The influence of various environmental factors on the distribution and quantitative indicators of the development of the mollusk population is estimated. It is shown that salinity is the key factor determining the expansion of the mollusk in the Sea of Azov.

IMPACT OF LOW SALINITY ON HEMOCYTES MORPHOLOGY AND FUNCTIONAL ASPECTS IN INVASIVE CLAM ANADARA KAGOSHIMENSIS (TOKUNAGA, 1906) -Kladchenko  E.S.,  Andreyeva  A.Yu.,  Kukhareva  T.A.,  Rychkova V.N.,  Soldatov  A.A.,  Mindukshev,  I.V.  - Impact of low salinity on morphology and function of hemocytes in ark clam species Anadara kagoshimensis was investigated using light microscopy and flow cytometry. In control group the water salinity was adjusted to 19.6‰, and experimental group was maintained at 14.8‰ and 8.8‰. Two cell types, amebocytes and erythrocytes, were identified in control group of ark clams. Erythrocytes constituted the main type of the cells, and amounted to 92.3±3.9 %. Hyposalinity changed that proportion: the number of amebocytes decreased 2.7 times and number of erythrocytes increased 7.6 times. Morphometric characteristics of hemocytes didn’t show statistically significant changes. As far as salinity decreased, the number of erythrocyte shades in hemolymph increased (3.5 times at salinity 8.8‰) and, in hemocytes, the reactive oxygen species (ROS) production grew (3.5. times at salinity 8.8‰).

ON DISTRTBUTION PATTERN OF AMORPHA FRUTICOSA L. IN THE REGION OF KANEVSKAYA HYDROPOWER STATION (UKRAINE) IN CONNECTION WITH HYDROCHORY - Shevchik  T.V.,  Dvirna  T.S.,  Shevchik  V.L.  - Amorpha fruticosa L. is a kenophyte of North American origin, ergaziophyte. Currently, this species naturalized over large areas and became the background on the coast waters of the Dnieper reservoirs of hydropower stations. It is necessary to clarify the reasons for the distribution of A. fruticosa populations in different parts of the Middle Dnieper coast under conditions of artificial regulation of its water yield. It has been proven that the high buoyancy of A. fruticosa fruits provides the possibility of its active dispersal along river beds in a natural way under conditions of fluctuations in the level of surface water yield right in spring floods. The main and determining factor in the active dissemination of the species on the coast of the Kanev and Kremenchug reservoirs is the frequent variability of the maximum water surface level. The narrow altitudinal range of distribution of this species on the coast in the lower parts, and accordingly, wider in the upper parts of the reservoirs is determined by the corresponding indicators of water level differences. The possibility of artificial regulation of the water surface level with knowledge of the characteristics of hydrochory of this invasive species makes it possible to influence its distribution in the territory near the reservoirs.

ABUNDANCE OF RELATED SPECIES, KELLICOTTIA BOSTONIENSIS (ROUSSELET, 1908) AND K. LONGISPINA (KELLICOTT, 1879) (ROTIFERA: BRACHIONIDAE), IN THE COMMUNITIES OF ZOOPLANKTON  OF THE PUSTYNSKAYA LAKE-RIVER SYSTEM (NIZHNY NOVGOROD OBLAST) - Shurganova  G.V.,  Zolotareva  T.V.,  Kudrin  I.A.,  Zhikharev  V.S.,  Gavrilko  D.E.,  Il’in  M. Iu.  - The article presents the features of the spatial distribution of zooplankton communities in the water area of the Pustynskaya lake-river system. The abundance of two related species of the genus Kellicottia, the alien Kellicottia bostoniensis (Rousselet, 1908) and the indigenous K. longispina (Kellicott, 1879), was analyzed in dedicated communities in 2013–2017. The greatest abundance of the alien species was noted in zooplanktocenoses of mesotrophic water bodies (the Serezha River and Lake Svyato). It was found that after the period of mass development of K. bostoniensis in 2013–2014, which might be due to the initial stage of naturalization of the alien species, its abundance had sharply decreased. In 2013–2014 the abundance of the indigenous species K. longispina (Kellicott, 1879) was significantly lower than that of the alien species. Rotifer K. longispina dominated in the Protoka and Lake Svyato in 2017. The highest density of both species was found in the metalimnion of the mesotrophic Lake Svyato. A statistically significant positive correlation was found between the abundance of K. bostoniensis and the temperature, transparency, and pH of water, as well as the abundance of predatory zooplankton species. The abundance of the native species K. longispina correlated negatively only with the value of water pH.
