Olive production is important to Algeria's economy and ecology, its cultivation has expanded significantly in recent years in Biskra region, increasing both area and production, with olive varieties that adapt well to local conditions. The Olive tree Olea europaea is a key species for maintaining the Algerian ecosystem and achieving sustainable food security, its integrity and abundance can affect other organisms that depend on them as a natural resource, but both the consumption and processing of olives are subject to a fearsome pest called Bactrocera oleae (Gmelin, 1790). This olive fly is considered one of the main pests of olives, capable of causing significant crop losses and damaging olive quality, against this context, we set out to assess the rate of olive infestation, our study has focused on showing certain aspects of the damage caused by olive fly infestation. we analyzed infestation rates on olive trees in three harvest seasons. We confirmed that their infestation is closely linked to climatic conditions, the cardinal directions, and the phenology of its olive tree host. Our study of the impact of Bactrocera oleae on olive production and food safety is essential for implementing appropriate control and management measures in olive groves.
