Abstract
Under constant temperatures from 10 °C to 25 °C Aphis craccivora reared on young and mature leaves of faba bean Vicia faba L. (Giza 2 variety), developed faster, had a higher mean relative growth rate and a higher intrinsic rate of increase on  young than on the mature leaves of faba bean. At temperatures above 25 °C there is a marked decline in the performance of the aphid. The intrinsic rate of increase is strongly correlated with the mean relative growth rate during development for both aphids reared on young and mature leaves from 10 °C to 25 °C.
