- * Its presence was confirmed through molecular-genetic analysis, and larvae were found in an artificial water source alongside other mosquito species.
- * The species successfully overwintered in Almaty during 2018-2019, indicating its ability to adapt to cold temperatures, which raises concerns about its potential spread to other regions, including Kyrgyzstan and Uzbekistan.
In this study, cytogenetic analysis of the metaphase chromosomes from imaginal discs of (Diptera: Culicidae) mosquitoes-, , , and -was performed. The patterns of C-banding and DAPI staining of the heteroсhromatin and the length of the chromosomes demonstrate species specificity. In particular, the chromosomes are the shortest compared with , , and , and they also carry additional C and DAPI bands in intercalary regions.

- Karyotypes of three Aedes mosquito species (Ae. excrucians, Ae. behningi, and Ae. euedes) were studied using metaphase chromosomes from imaginal discs.
- Various staining techniques (lacto-aceto-orcein, C-banding, and DAPI) revealed unique morphological and length characteristics of the chromosomes specific to each species.
- The differences noted, particularly in chromosome 1 and the arrangement of heterochromatin blocks, can be used for identifying these mosquito species.
Article Synopsis
- This study reports the first identification of three Anopheles species—An. kleini, An. pullus, and An. lesteri—in the Primorsk and Khabarovsk regions of Russia.
- The research utilized molecular taxonomic diagnostics and found that the previously thought dominant species, An. sinensis, was not present in these areas.
- Analysis of nucleotide variation in the cytochrome c oxidase subunit I (COI) region revealed distinct sequences for each species and led to the construction of a phylogenetic tree grouping the Anopheles hyrcanus members into two monophyletic subgroups.
