                 Summary
                 In the present study, the seasonal distribution of stored product insects was recorded, spatially
                 visualized, and evaluated in a feed production industry in Northern Greece. The installation of
                 the trapping network was established in July 2021 and the monitoring lasted from August 2021
                 until April 2022. A total of 30 Dome traps (Trece Inc.) were installed for crawling insects and
                 8 hanging Delta traps (Trece Inc.) for Lepidoptera. Οil (Storgard Oil, Trece Inc.) was used as
                 an attractive agent at Dome traps, while for the Delta traps pheromone was used for Plodia
                 interpunctella (Lepidoptera: Pyralidae) and Ephestia spp. (Lepidoptera: Pyralidae). All insect
                 samples taken were transferred to the Laboratory of Entomology and Agricultural Zoology for
                 counting and identification. Furthermore, using relevant Python libraries, the data were
                 spatially visualized based on the building floor plan. This process enabled the identification of
                 zones/areas in the building with the higher insect activity. The results showed that in the
                 summer months the captures were significantly higher than in the winter months, with the
                 highest number of insects being recorded on 02/09/21 (999 individuals). The dominant stored
                 product species for the summer period were certain stored product moths, including P.
                 interpunctella and the genus Ephestia spp., as well as the tobacco beetle, Lasioderma
                 serricorne (F.) (Coleoptera: Anobiidae). In contrast, during the winter months the populations
                 of the aforementioned species were decreased significantly and increased the species Sitophilus
                 granarius (L.) (Coleoptera: Curculionidae), Tribolium confusum Jacquelin du Val (Coleoptera:
                 Tenebrionidae) and Oryzaephilus surinamensis (L.) (Coleoptera: Silvanidae). The insect
                 monitoring and the spatial visualization will continue for another year in order to assess the
                 levels of insect populations and therefore to apply focused solutions depending on the insect
                 species and the area of infestation.
