The Arabian rhinoceros beetle, Oryctes agamemnon arabicus, has emerged as a signifiicant pest of date palms in Algeria, infilicting considerable damage on these crucial agricultural ecosystems. This study provides a thorough morphological description of Oryctes collected from date palm oases in El Oued, Algeria, during the period from 2022 to 2024. Through careful identifiication of the specimens, it was confiirmed that O. a. arabicus is the only subspecies present in the region, highlighting its specifiic ecological role. The fiindings emphasize the necessity of detailed morphological analyses for accurate species identifiication, which is crucial for effective conservation strategies. By enhancing our understanding of these beetles, this research contributes valuable insights into pest management practices that are essential for mitigating the impact of Oryctes infestations. Ultimately, the outcomes of this study advocate for targeted conservation efforts of date palm and sustainable agricultural practices, ensuring the protection of date palms and the resilience of the agricultural landscape in Algeria.
