By analysis the crop contents, the two phthirapteran species that infest helmeted guinea fowls, Numida meleagris (Linnaeus, 1758), Lipeurus tropicalis Peters, 1931 (Ischnocera) and Menopon gallinae (Linnaeus, 1758) (Amblycera) have been investigated. 83% of the M. gallinae (Linnaeus, 1758) specimens in the crop had crimson contents that were consistent with host blood, while 87% of the L. tropicalis Peters, 1931 specimens in all stages had feather barbules. There were no signs of any triturating agents, dead skin pieces, or body parts of other lice or insects

The examination of the crop contents from two phthirapteran species, Menopon gallinae (Linnaeus, 1758) and Lipeurus tropicalis Peters, 1931, infesting helmeted guinea fowl, Numida meleagris (Linnaeus, 1758), yielded noteworthy findings. Consistent with expectations, Lipeurus tropicalis Peters, 1931 was identified as a feather feeder, while Menopon gallinae (Linnaeus, 1758) was recognized as a blood feather. However, no triturating agents such as granules, quartz, mica, sand grains, seed coats, or cuticular processes commonly observed in other species were detected
