Abstract: Response of faba bean to irrigation with wastewater obtained from different wastewater treatment plants along with the combined effect of wastewater and aphids on plant growth and aphid fitness were evaluated under greenhouse conditions. Results indicated that the pH, electrical conductivity, total dissolved solids, and macro-elements were varied widely among wastewater resources and were higher than that of tap water. Seed germination percent did not significantly affect by wastewater, but germination index was considerably influenced by some types of wastewaters. Plant growth was reduced by irrigation with Wadi Hassan wastewater and Zarqa river. Leaf macro-elements greatly varied between treatments. Aphid infestation reduced plant growth compared to the control. Plants treated with wastewater enhanced the abundance of aphids at different magnitudes, while plant growth was equal and/or better than that of infested control plants. We conclude that the properly treated wastewater was not only as effective as fresh water in enhancing the plant growth, but also mitigated the adverse consequence of high infestation level of aphids on the plant.
