Genetic Structure of () Populations in Russia.

Background: () was found for the first time in 2011 on the Black Sea coast in Russia, and during 2011-2019, the species expanded over two climate zones Cfa and Csa.

Methods: Here, we studied the sequence diversity of the mitochondrial cytochrome c oxidase I () gene, 1317-1433bp in length. In total, 131 specimens of sampled from 21 locations in Russia and Abkhazia were examined.

Symbiotic Wolbachia bacteria in coccinellid parasitoids: genetic diversity, horizontal transfer, and recombination.

Parasitoids, which constitute about 25% of all insects and attack arthropods of virtually all taxa, are considered the most suitable vectors for horizontal transmission of the symbiotic bacterium Wolbachia among insects. The parasitoids studied in this article develop in the larvae and pupae of ladybirds. For the first time, Wolbachia was found in parasitic wasp species of the genus Homalotylus (Hymenoptera: Encyrtidae) and from the subfamily Tetrastichinae (Hymenoptera: Eulophidae).

Wolbachia, Spiroplasma, and Rickettsia symbiotic bacteria in aphids (Aphidoidea).

Aphids are a diverse family of crop pests. Aphids formed a complex relationship with intracellular bacteria. Depending on the region of study, the species composition of both aphids and their facultative endosymbionts varies.

Detection of the Invasive Mosquito Species () and () on the Southern Coast of the Crimean Peninsula.

Background: The incidence and area of arbovirus infections is increasing around the world. It is largely linked to the spread of the main arbovirus vectors, invasive mosquito of the genus Previously, it has been reported that reemerged in Russia after a 50-year absence. Moreover, in 2011, was registered in the city of Sochi (South Russia, Black Sea coast) for the first time.

Wolbachia symbionts in mosquitoes: Intra- and intersupergroup recombinations, horizontal transmission and evolution.

Many mosquitoes harbour Wolbachia symbionts that could affect the biology of their host in different ways. Evolutionary relationships of mosquitoes' Wolbachia infection, geographical distribution and symbiont prevalence in many mosquito species are not yet clear. Here, we present the results of Wolbachia screening of 17 mosquito species of four genera-Aedes, Anopheles, Coquillettidia and Culex collected from five regions of Eastern Europe and the Caucasus in 2012-2016.
