Mites (Acari, Oribatida) of selected organic farms from the Kujawy-Pomerania Province

The experiment was carried out on 3 organic farms in the Kujawy-Pomerania Province in 5 different habitats to determine the number and species composition of mites. Ten replicate samples of 50 cm 3 and 17 cm 2 were collected in 2011 from 3 layers, so altogether 780 samples were collected. In total, 14 taxa of Oribatida were identified. The total number of mites and Oribatida significantly differed in the analyzed habitats. Tectocepheus velatus [Michael, 1880], Scheloribates laevigatus [C.L. Koch, 1835], Punctoribates punctum [C.L. Koch, 1839] and Eupelops occultus [C.L. Koch, 1835] were the most abundant oribatid mite species.
