Samples were collected from mattresses, pillows and carpets by vacume cleaner collected material was kept in a plastic bag and sent to the laboratory. 200 mgs of dust particles were placed in a petridish and observed under minocular considering the anti light property of mites, they remained under the layer of dust and were picked up by an entomology needle and kept in 70% alcohol. Lighting of sample, neutraliztion and finally assembling were done in hoyer solution for identification after mounting. Âll the data about the mites were recorded in a questionnair and analyzed statistically.
Results : Ïn this study, 3400 mites were hunted and 5 species could be identified as follows: D. Pteronyssinus, D. farinae, Glycyphagus domesticus, Ë. moynei and Çheylatus malayensis.
