Abstract

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.
