Observations on the microclimate of habitats of Anopheles hyrcanus and Anopheles maculipennis sacharovi were carried out in the region of the Uzbekistan Rice Test Station. The habitats of A. hyrcanus are usually thickets of velvet grass (Holcus mollis) in rice fields. In living quarters, in places where domestic animals are kept, this species is found very rarely. The habitats of A. m. sacharovi are stables. Results are presented of observation on soil and air temperature, humidity and wind velocity in habitats of mosquitoes and their comparison with the microclimate of the open area of the meteorological station located in the vicinity. Data obtained upon measurements of solar radiation in the biotopes A. Hyrcanus and A. m. sacharovi have been published previously.
