Dust mites are very potent indoor allergen, live in close association with human being and cause several types of allergic disorders, but still there is limited knowledge about species composition and abundance of dust mites in different human habitats, especially in Jharkhand. In this study flour mill dust samples were examined to study prevalence and species composition of dust mites in flour mill, to provide better information about diversity of flour dust mite. Total eight Species of dust mites were present in flour dust, belonging to the seven genera, five family and three orders namely Astigmata, Prostigmata and Mesostigmata. Dermatophagoides pteronyssinus (49.03%) of family Pyroglyphidae was the most abundant and dominant species followed by Blomia tropicalis (21.27%) of the family Glycyphagidae, Acarus siro (15.51%) of the family Acaridae and Cheyletus eruditus (8.32%) of the family Cheyletidae. The population of dust mite was higher during July to October, while in May there were no mites present in the samples.
