The specific composition of acarid mites occurring in dust of rural dwellings in the Far East of the USSR has been first studied and characters of their fauna have been revealed. 3 species are most frequently encountered of which Dermatophagoides pteronyssinus accounts for 56% of all finds. 6 species happened to be new for the fauna of dwellings. The typical synanthropic species Glycyphagus domesticus is totally absent from dwellings but occurs in 90% of honey-bee hives.
