Population dynamics of juveniles and cysts of corn cyst nematode, Heterodera zeae under stress of a cropping sequence regime revealed that the average numbers in each stage greatly fluctuated. The density of juveniles or cysts gradually increased with the favorable host (Giza 2 corn) to reach its peak at the crop maturity, while the nematode population dropped sharply when the field became fallow. Likewise, the population densities of the previous stages declined gradually even though in the presence of the non host crop (Meskawii Egyptian clover).
