Selected haemetophagous phthirapterans have been convicted to act as reservoir and transmitter of pathogens among their hosts. Amblyceran Phthiraptera are generally believed to exhibit varying degree of haemetophagy. The microscopic examination of 100 adults (both sexes) and 47 nymphal instars of an amblyceran louse, Colpocephalum turbinatum revealed their non haemetophagous nature as any red content compatible with host blood was not detected in their crops. The crops of the lice were found packed with only feather barbules. On seven instances the pieces of egg chorion and in 20 cases the presence of epidermal tissue were also detected in crop contents. However, the presence of any triturating agent (any structure which can help in grinding the feather contents) was not noticed. SEM studies on the ventral side of the head of the louse do not indicate the presence of any pointed gear which can be used to pierce the skin blood vessels of host. Present study suggests that few amblyceran species of Phthiraptera are not in haemetophagous in nature.
