Hadjelia truncata کرم کبوتر
Hadjelia truncata belongs to the order Spirurida, superfamily Habronematoidea, family Hedruridae and genus Hadjelia (Anderson, 2000). This worm has been found in the gizzard of a number of bird species in Europe and Asia. The intermediate host are variuos beetles (Anderson, 2000). So far, there have been only three reports of the pigeons infestation with this parasite from Egypt (Tadros and Iskander, 1975), Iraq (Al-Attar and Abdul- Aziz, 1985), Saudi Arabia ( Omer Farah, 1988) , Cyprus (Appleby et al., 1995) and Iran ( razmi et al.,2006 ). This is the second report of the H. truncata infestation in the gizzard of pigeons in Iran
The morphology of the nematodes were examined by light microscope. The length of male and female were 7-9 mm and 13-17 mm, respectively. Microscopical examination of cephalic region was revealed two lateral lips, each being trilobed with cylindrical pharynx The morphology of caudal region of male was
characteristic of the spirurid-type. There were two unequal and dissimilar spicules, one 1.26 mm long and the other 0.34 mm long. The tail was coiled and 2 wide caudal
