Hydrochemical regimen of the sites of emergence as a measure of the ecological plasticity of the mosquito Aedes caspius dorsalis Mg. (Diptera, Culicidae)

The results of the analysis of the hydrochemical regime of the A?des caspius dorsalis emergence places at the northern border of its distribution, on the White Sea coast are presented. The larvae of this species are able to grow in the various reservoirs under the different conditions which have been changed during larvae development. The dynamics of hydrochemical characteristics depends on the hydrological regime of these reservoirs. The larvae ability to endure considerable changes of the abiotic factors shows the great adaptive tolerance of the species.
