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.
在45头自然感染的骆驼头部研究了羊狂蝇幼虫的定位和迁移途径。幼虫分布于咽腔（95.6%）、筛骨迷路（71.1%）、鼻甲（28.9%）和下鼻道（6.7%）。在261只一龄幼虫中，73.7%位于筛骨迷路，26.3%位于鼻甲；而二龄幼虫88.9%见于咽腔，11.1%位于筛骨迷路。大多数三龄幼虫（91.9%）位于咽腔，少数幼虫在筛骨迷路（6.5%）和下鼻道（1.6%）。第一次蜕皮发生在筛骨迷路。在筛骨迷路和咽腔均观察到第二次蜕皮。讨论了这些幼虫在受感染头部的迁移途径。
