Cephalopina titillator had adverse effects on the camel health such as difficult breathing, reduction of milk production, fertility, and tissue damage. Therfore; this study aimed to describe of the fine ultrastructure of the adult fly and different stages of larvae using light and scanning electron microscopy (SEM). The larvae collected from the slaughtered camel at Cairo slaughter-house from January to May 2019. The second and third instar larvae of C. titillator were collected from the nasal passages; sinuses and turbinates. The pseudocephalon of the third larval stage had two long curved maxillae and two antennary lobes which provided several sensory papillae. However, the last abdominal segment showed two peritremes in a deep pit surrounded with two lips that contain several large sensory papillae and small spines at the tegument surface. Many basiconic sensilla are situated on the ventral depression close to the posterior spiracular. Sensilla on insect body parts play an important role in their behavior for deposited larvae. This is the first overall observation about sensilla on the whole body of Cephalopina titillator adults and larvae, which have great significance on the behavior, identification, and evolution of the adult fly.

骆驼鼻机器人不同阶段的精细结构;Cephalopina titillator(双翅目:Oestridae)

Cephalopina titillator 对骆驼的健康有不利影响,例如呼吸困难、产奶量减少、生育能力和组织损伤。因此; 本研究旨在使用光学和扫描电子显微镜 (SEM) 描述成蝇和不同阶段幼虫的精细超微结构。2019年1月至5月在开罗屠宰场屠宰骆驼的幼虫。C. titillator二、三龄幼虫从鼻腔收集;鼻窦和鼻甲。第三期幼虫的假头具有两个长弯曲的上颌骨和两个触角叶,提供几个感觉乳头。然而,最后一个腹部节在一个深坑中显示了两个边缘,周围有两个嘴唇,在外皮表面包含几个大的感觉乳头和小刺。许多碱性感受器位于靠近后气门的腹侧凹陷处。昆虫身体部位上的感觉器在其沉积幼虫的行为中起着重要作用。这是第一次对头翅目蠊 成虫和幼虫全身感受器进行全面观察,对成蝇的行为、识别和进化具有重要意义。
