Seasonal dynamics of the renifonn nematode. Rotylenchulus reniformis in soil and roots and the spiral nematode. Nelicotylenchus sp. in soil of olive (Oleo europaea L.) cv. Toffahi over one year were analyzed. Population densities of both nematodes reached higher populations in spring with the onset root growth through summer and winter and significantly (p<0.05) declined in autumn revealing that these nematodes were negatively correlated with the prevailing soil temperature (°C) and were positively correlated with percentage soil moisture at different sampling months and seasons. Correlation coefficients (r) were calculated to ascertain these relationships.
