| Abstract | ||||
| The present study was done to determine the effect and evaluate of three infestation levels 0, 5 and 10 aphids (Aphis craccivora Koch) / plant on faba bean, V. faba L. plans (Giza 402 cv.) at different parts and statues of plant over four infestation periods. The result of this study showed that significant effect of initial aphid infestation, time of infestation and periods after infection (feeding period) all treatments, on the weight of both shoot and roots (fresh and dry) and the plant height. Faba bean plants were died at the fourth week after infestation. A. craccivora individuals were developed during low infestation level (5 individuals) and significant but less than numbers during high initial infestation (10 individuals). | ||||
