Summary: | The peculiarities of the dynamics of malaria mosquito species proportions were studied in natural populations. Twenty-one collections from five larval habitats of the
Anopheles maculipennis
complex malaria mosquitoes were taken in the vicinity of Novosibirsk (Russia). It was detected that the
Anopheles messeae
and
An. daciae
are dominant species in the collected samples. Three
An. beklemishevi
individuals were also detected. The dynamics of the species proportions within the reproduction seasons for a number of years and also the differences between localities in the species composition were studied. It was revealed that the
An. daciae
proportion is maximal in July and falls in August. The species proportions can change sharply from year to year. For example, the
An. messeae
species prevailed in localities on the left bank of Novosibirsk Reservoir in 2013 and 2014 with the frequency of 54–68%, while
An. daciae
began to prevail on this territory in 2016 with the frequency of 73–85%. Our data on the proportions of species in different reservoirs were compared with data of other authors for the collections of malaria mosquitoes of the
Anopheles maculipennis
complex in Russia (Tomsk oblast) and in Germany. A high correspondence of models provided by these authors for the territory that we studied was demonstrated. Thus, the ecological peculiarities of the
An. messeae
and
An. daciae
species are highly stable even in geographically and climatically distant localities. An increase in the portion of relatively anthropophilic
An. daciae
in the middle of summer can be a risk factor relative to malaria transmission in this period of time. |
