Abstract: Mites are among the most diverse and successful of all the invertebrate groups. They have exploited an incredible array of habitat and act as ectoparasite. Animals with mite infestations have varying clinical signs ranging from none to mild alopecia to severe pruritus and ulcerative dermatitis. Mites have been shown to be important sources of indoor allergens associated with asthma and other allergic conditions in sensitive victims. Hence the monthly and seasonal study has been carried out in the intramural environment of rat house at Pune, for one year (for three seasons) from February 2015 to January 2016 to analyze the environmental impact on the incidence, population density, monthly variation, seasonal variation and dynamics of rat mite fauna by ‘simple pickup technique’ under stereo binocular dissecting microscope and Leica binocular research microscope. Total 593 mite specimens have been screened, identified and classified into male and female under eight genera including five species and three unidentified species named as Echinilaelaps echidninus (Ee), Haemolaelaps glasgowi (Hg) belonging family Laelaptidae and Gohieria fusca (Oudemans) (Glycyphagidae, Cheyletus eruditus (Cheyletidae), Dermatophagoides farinae and Unidentified U1,U2,U3. Echinolaelaps echidninus has been found dominant species during rainy 253 (42.66%) followed by summer season 92 (15.51%) and winter season 69 (11.64%). Haemolaelaps glasgowi contributed 51 (8.60%) in rainy season, 40 (6.74%) in summer season and 80 (13.49%) in winter season. Other specimens like Gohieria fusca (0.33%), Cheyletus eruditus (0.33%), Dermatophagoides farinae (0.16%) and Unidentified specimens (U1, U2, U3) and one unidentified larva has been also observed. The Ee has been found to be dominant 414 (69.81%) species followed by Hg 171 (28.83%0 and very few specimens of other genera.
