In this study, we present the first archaeobotanical evidence for bruchid beetle (Chrysomelidae: Bruchinae) infestation of Vachellia trees from the Christian site at Banganarti, located on the right bank of the Nile in Northern Sudan. Since 2019, extensive systematic archaeobotanical sampling has been conducted in the NECH and SSCH sectors of the site. A total of 63 soil samples were collected, subjected to flotation, and sieved using 2.0 and 0.5 mm mesh sizes. Subsequent processing and identification were performed using light microscopy, multidetector computed tomography (CT), and scanning electron microscopy (SEM). Identification, based on anatomical and morphological comparisons with reference collections, revealed a diverse assemblage of domesticated and wild plants. In two selected Vachellia seed samples, BA-19 P211 and BA-19-P113, CT and SEM analyses revealed characteristic internal features indicative of bruchid beetle infestation. Infestation traces were observed in a total of eight seeds of V. nilotica and six seeds of V. tortilis. Two of the best-preserved specimens from each species were selected for SEM imaging. The scans provided evidence of larval tunnels and internal boreholes, confirming bruchid larval development within the seed coat and subsequent emergence via perforation of the seed surface. These findings extend the record of insect–plant interactions in Sub-Saharan Africa and highlight their implications for human–plant relationships during the Christian period.
