Abstract\\r\\nA checklist of soil mites sampled in three Daya steppe areas with pistachio plantations in Djelfa, Algeria, Daya Ben Harrath, Daya Ben Toumi and DayaBoxden is presented. Twelve soil samples were collected in 2013 at each Daya during the months fromJanuary to April. The samples were processed using Berlese funnel for mite extraction. All mites collected belong to 4 orders: Trombidiformes, Acarina, Oribatida and Uropodina. The total number of individuals collected from the three Dayas was 470 representing 6 mite species in Daya Ben Harrath 106 individuals were captured belonging to 4 orders, 4 families and 4 species ; 162 individuals were collected in Daya Ben Toumi belonging to 4 orders, 5 families and 5 species; and 202 individuals were collected in Daya Bowden within 3 orders, 4 families and 4 species. The species Rhizoglyphus was the most abundant in the three Dayas, in Daya Ben Harrath with 87 individuals (81.1% of the total number of collected individuals), Daya Ben Toumi with 144 individuals (88.9%) and Bowden with 192 individuals (95.1%). The maximum mite density was recorded inDaya Ben Toumi 600 mites/m2followed by Daya Bowden 733.33 mites/m2and in Daya Ben Harrath, density was lowest(392.6 mites/m2). The Shannon-Weaver diversity index values were low in the three Dayas, 0.63 (Bits), in Daya Ben Harath 0.48 (Bits) in Daya Ben Toumi and 0.24 bits in Daya Bowden.\\r\\nKeywords: Mites, pistachio of Atlas, Daya, Berlese funnel, Djelfa (Algeria).
