Herbicides are synthetic chemicals that extensively employed in agricultural practices with the objective of enhancing crop yield and quality. Despite their selectivity for plant systems being generally regarded as non-toxic to animals, there is a paucity understanding surrounding sublethal effects on non-target organisms, including animals. This gap underscores necessity ecotoxicological research prioritizes identification suitable models develops reliable biomarkers early assessment environmental impact. In this context, hemocytes—circulating immune cells found invertebrates—have been identified crucial system assessing toxicological effects, given role defense overall organism health. Tenebrio molitor, beetle pest stored grain, was used model metribuzin-based herbicide (MTB, Feinzin DF 70, 70% metribuzin, 0.25 kg ha−1). Following 96 h exposure MTB, males (7–10 days post-eclosion) were examined multiple hemocytes, cell density, phagocytic activity, lysosomal membrane stability, cytological changes. Although no mortality observed, MTB resulted reduction index an increase blast-like cells, indicating potential immunotoxicity. Lysosomal stability reduced, though significant changes hemocyte density or nuclear morphology observed. These responses indicate impairment, which could affect beetle’s fitness reproductive potential. study highlights hemocytes raising concerns about ecological impact herbicides agroecosystems risks both wildlife human
