Localization and migration route of Cephalopina titillator (Diptera: Oestridae) larvae in the head of infested camels (Camelus dromedarius).
The localization and migration routes of Cephalopina titillator larvae were studied in the heads of 45 naturally infested camels. Larvae were located in the pharyngeal cavity (95.6%), the labyrinth of the ethmoid bone (71.1%), the turbinates (28.9%) and the lower nasal meatus (6.7%). Out of 261 first-instar larvae, 73.7% were found in the labyrinth of the ethmoid bone and 26.3% in the turbinates, while 88.9% of second-instar larvae were observed in the pharyngeal cavity and 11.1% in the labyrinth of the ethmoid bone. Most third-instar larvae (91.9%) were found in the pharyngeal cavity, with a few larvae in the labyrinth of the ethmoid bone (6.5%) and lower nasal meatus (1.6%). The first moult occurred in the labyrinth of the ethmoid bone. The second moult was observed in both the labyrinth of ethmoid bone and the pharyngeal cavity. The migration route of these larvae in the infested head was discussed.
