Abstract
The article considers materials related to current areas of fundamental research in the field of agricultural entomology in Algeria. The most important issues of agricultural entomology in Algeria include identifying patterns of general trends in the dynamics of geographic ranges of phyto-entomophagous under the influence of climatic and anthropogenic factors, as well as studying the adaptation of insects to new habitats and food supply. In a notable discovery during insect sampling conducted in the oasis ecosystem during the summer of 2019, researchers recorded and identified individuals of the species Caenocoris nerii (Germar, 1847) for the first time. These insects were observed feeding on cultivated fig trees growing beneath palm trees at the experimental site belonging to the Technical Institute for the Development of Agriculture in the Sahara (ITDAS, Ain Ben Noui). This finding is significant as it represents the first recorded instance of C. nerii in the Biskra oasis ecosystem, as well as the first documentation of the insect feeding on Ficus carica L. (Fig trees), its newly identified host plant. Prior to this discovery, C. nerii had not been associated with F. carica L. as a food source. The discovery marks an important addition to the knowledge of insect-plant interactions in the region and contributes to the broader understanding of agricultural entomology in Algeria. Although present, C. nerii has limited known impact. Yet, its feeding habits and the region’s agriculture warrant monitoring for potential outbreaks.
