This work aims to establish an ecologically integrated pest management strategy to assess the effect of water and nitrogen depletion on Myzus persicae infestation in the peach orchard. The results showed a significant effect of level of water and nitrogen supplies on the green peach aphid infestation in the orchard. Indeed, the fertigation regime T1 (100) proved to be much more favorable to a prominent development of aphidian populations compared to 25 water and nitrogen restricted regime. Moreover, the infestation degree was lower in the regime T2 (~75) than that observed in the regime T1. The evolution of wingless and winged green aphid populations was similar in both regimes. The effect of branch orientation on the aphids infestation was significant with those oriented to the North, West and South were more infested than those oriented to the East. Concerning the useful fauna, we noticed the same predators species for all the tested regimes. A negative effect on Stethorus sp and Chrysoperla carnea densities was appeared under water and nitrogen depletion. © 2017, University of Mohammed Premier Oujda Morocco.
