Soil symbiotic bacteria can be useful factors in increasing the resistance of plants against herbivorous insects. The two treatments investigated in this research included the bean plant treated with bacteria and the bean plant without bacteria treatment as a control. The Vicia faba L. and black bean aphid were grown in a growth chamber at 25±4 0C, %50±5 RH and a photopriod of 14L: 10D hours. Then, 5 ml of bacterial suspension was added into the soil of sown mugs with a sterile syringe. These experiments on the effect of two treatments on faba bean showed that different treatments have a significant differences effect on the biological properties of black bean aphid. The highest developmental time (19.78±0.20 days) and the lowest fertility rate were occurred on P. polymyxa. There were significant differences between different treatments in terms of inherent rate of population increase (P≤0.5). The highest rate was occurred in control treatment (0.42±0.01 day-1) and the lowest in combination P. polymyxa (0.23±0.001 day-1). The life expectancy of black bean aphids, which was grown on P. polymyxa treated, was significantly lower than control. According to the results, it can be stated that faba bean plant treated can be effective in reducing the population of the aphids of the bean.
