The vertical distribution of soil oribatid mites and its dependence on ecological parameters such as soil temperature, moisture, pH and organic matter content were studied in an age sequence of 22-year-old Mangifera indica L. plantations in Ismailia, down to a depth of 30 cm. The results showed that the numbers of total oribatid mites exhibited a gradual decrease trend with depth. The number of oribatid mite species was significantly lower in 20-30 cm depth than the tope layers (p <0.05). Pergalummna flagellate Grandjean and Oppiella nova (Ordemans) dominated in the upper 10 cm soil and their numbers strongly decreased with depth. Most of oribatid mites had an annual fluctuation in their abundance and population changes, which related to seasonal changes in the temperature and moisture contents of the soil. Soil moisture was positively correlated with total mites; while soil temperature had negative correlation.
