Cytogenetic and environmental analysis of the populations of the Anopheles messeae mosquito of the eastern Kazakhstan region and in the foothills of Alatau

Cytogenetic analysis of populations of larvae of malarial mosquitoes of the East Kazakhstan region (Semey city, Urdzhar village) and in the foothills of Alatau. In the village of Urdzhar identified two species Anopheles: An. claviger and An. message; in the remaining studied areas - only An. messeae. In populations An. messeae established a high level of inverse polymorphism on the sex chromosome and the third autosome. Significant differences between alternative samples for the composition of inversions and the frequencies of their variants due to the ecological peculiarities of the regions were recorded. In the south of the species range (Almaty agglomeration) over the past decades, a significant change in the frequency of chromosome inversions associated with climate change has been revealed

Mosquitoes of Anopheles hyrcanus (Diptera, Culicidae) group: species diagnostic and phylogenetic relationships

Herein, we report the results of study of Anopheles species in Primorsk and Khabarovsk regions of Russia. Three species of the Anopheles hyrcanus group: An. kleini, An. pullus, and An. lesteri were identified by molecular taxonomic diagnostics for the first time in Russia. Surprisingly, An. sinensis, which earlier was considered the only species of Anopheles in Russian Far East, was not observed. We analyzed nucleotide variation in the 610-bp fragment of the 5' end of the cytochrome c oxidase subunit I (COI) region. All species possessed a distinctive set of COI sequences. A maximum likelihood phylogenetic tree was constructed for members of the hyrcanus group. The examined Anopheles hyrcanus group members could be divided into two major subgroups: subgroup 1 (An. hyrcanus and An. pullus) and subgroup 2 (An. sinensis, An. kleini, and An. lesteri), which were found to be monophyletic

Analysis of the metaphase chromosome karyotypes in imaginal discs of Aedes communis, Ae. punctor, Ae. intrudens, and Ae. rossicus (Diptera: Culicidae) mosquitoes

In this study, cytogenetic analysis of the metaphase chromosomes from imagina

First record of the invasive mosquito species Aedes koreicus (Diptera, Culicidae) in the Republic of Kazakhstan

The natural distribution range of Aedes koreicus is Korea, China, Japan, and the Russian Far East. Since 2008, this species has been recorded as an invasive species in some European countries (Belgium, European Russia, Germany, Hungary, Italy, Slovenia, and Switzerland). The invasive mosquito species Ae. koreicus is reported from the Republic of Kazakhstan for the first time. Its morphological identification was confirmed by molecular-genetic analyses of ND4 sequences using specific primers. Aedes koreicus larvae were found in an artificial water reservoir together with the larvae of Culiseta longiareolata and Culex pipiens s.l. Aedes koreicus successfully overwintered in Almaty at low winter temperatures in 2018–2019. This suggests that the Ae. koreicus acclimation capacity is greater than it has been considered until now. We assume that Ae. koreicus will spread over the west and south of the Republic of Kazakhstan and territories of Kyrgyzstan and Uzbekistan Republics bordering the Almaty region

Species diversity of blood-sucking mosquitoes (Diptera: Culicidae) in Tomsk Region

This article describes the results of studying the Culicidae species composition in Tomsk region, during 8 years, 2008–2015. The survey revealed 31 mosquito species of five genera, namely Anopheles, Culex, Culiseta, Coquillettidia, Aedes. Dominant, numerous, common and rare species of Aedes genus were detected. The complete list of Culicidae species in Tomsk region was recorded. Ae. annulipes and Ae. sticticus were included in the species composition of Siberia; their presence in Tomsk region had previously been doubted. Some other species were deleted from the list because they were absent at the present time
