The Saoura region, a renowned oasis in North Africa with heritage and archaeological significance of both national and universal importance, has witnessed a gradual deterioration over time. This research involves archaeological predictive modelling, aiming to create models capable of predicting the likelihood of discovering archaeological sites, cultural resources or evidence of past landscape use within a specific region. The study specifically focuses on predicting the locations of historical sites in the Sahara Desert, employing the maximum entropy (MaxEnt) model and six geo‐environmental criteria, including slope, elevation (digital elevation model [DEM]), distance from water, normalized difference vegetation index (NDVI), fertility and proximity to palm groves. The research is based on data from 58 historical sites and includes an assessment of the model's accuracy. The study highlights the remarkable significance of the fertility variable, which accounts for 94.1% of the predictive influence, making it the most crucial geo‐environmental factor in forecasting the location of historical sites in the Sahara. This underscores its pivotal role in shaping settlement patterns and subsistence strategies within the region, followed by the distance variable from the palm cove (3.2%) and the distance variable from the river (2.3%). The MaxEnt model proves to be suitable for predicting historical site positions, with an impressive average area under the ROC curve (AUC) score of 0.859, reflecting its effectiveness. Notably, areas with a high prediction probability are predominantly situated near the Saoura Valley. The study's findings hold the potential to assist planners in safeguarding archaeological sites by avoiding areas where historical sites are likely to be present. [ABSTRACT FROM AUTHOR]

The study of some bioecological aspects of Viracholalivia was carried out in two regions (Ouargla and Touggourt) in southeastern Algeria. On pomegranate, the infestation by this pest starts as soon as the inflorescences appear (mid-March).At the ripening of pomegranates this rate arrives at 15.01%, 16.14%, and 18.22% respectively for the years 2017, 2018 and 2019. The female generally prefers to lay her eggs in the half of the fruit close to the calyx with a preference for the southern orientation. V. livia shows polyphagy within several fruits in the surveyed palm groves. [ABSTRACT FROM AUTHOR]
