Abstract: This work aims at developing an integrated and ecological control strategy of pest management to assess the impact of water and nitrogen resources on aphid infestations and growth and production parameters in the orchard of peach. The results obtained in the study of the green peach aphid show a significant effect on the availability of water and nitrogen on the level of infestation of green peach aphid. Indeed, the most favorable fertilization regime (T1 = 100 %) has proved much more favorable to a prominent development of aphid populations, while deficit procedure (T2 = 75 %) could minimize infestations thereof. Parallel to this finding and regarding growth and production parameters of the trees, reducing water and nitrogen intake does not affect their evolution. Instead, foliar analyzes and analyzes of fruit from both fertilization regimes have shown no significant difference with regard to their physical and chemical characteristics.
