Abstract : Soil and root samples collected from the rhizosphere of 6 cultivars of mango in Giza, Egypt contained mixed populations of 11 genera of plant-parasitic nematodes. Rotylenchulus reniformis, Helicotylenchus dihystera and Criconemella sp. were very common and their population densities were higher than those of the other nematode genera. Alphonse and Hindi cultivars harboured a high number of nematodes. Population densities of R. reniformis and H. dihystera were found to be low during winter months on all 6 cultivars. R. reniformis population increased continuously from the beginning of spring and reached the peak in autumn at all cultivars except Taimour and Zebdia, while H. dihystera population had two peaks, one in spring and the other in autumn on all cultivars except Taimour and Zebdia.
