Four ages of corn Zea mays L., cultivar Giza 2 were used to evaluate its influence on infectivity, development and virulence of Heterodera zeae. The results revealed that the nematode final population and rate of build-up correlated negatively with the host age. The nematode multiplied highly on the youngest seedlings; and was more virulent on the youngest than on the oldest plants.
