Field studies conducted during two wheat growing season of (2000-2001) in Banie Swief Governorate, Middle Egypt to detect field population of Cereal Aphids, Schizaphis gramimum. Field generation numbers, thermal heat units required and life table parameters were estimated. The Cereal Aphids, Schizaphis gramimum was found to have 6 generations during wheat growing season that extended from December to April. Generations occurred at an average of 94.451.272 The lower threshold was 8.88 oC. The intrinsic rate of increase was varied according to each generation .

Species 1: Homoptera Aphididae Schizaphis graminum (Cereal Aphid)
