       This investigation was carried out on cattle slaughtered in Sarab abattoir during four seasons of the year. In order to find second and third instar hypoderma larvae, area under the skin and body surface were examined and for first instar larvae, the internal surface of the esophagus from its cranial to caudal end and the spinal canal from cervical to sacral regions were examined in slaughtered cattle. In this study, from a total of 453 slaughtered cattle which were examined, first  instar larvae of Hypoderma bovis were found in the epidural fat of the spine initially in November - December (0/03%), the larvae continued to be found in the spine canal for the next four months. The peak rate of infestation was 0/2% in January - February. The second and third instar larvae of  Hypoderma bovis and Hypoderma lineatum were found initially in subcutaneous tissues and body surface of  slaughtered cattle February (0/14%) and their presence continued till July - August of the following year. Maximal infestation rate of the subcutaneous tissues was recorded during March - April (0/21%). The findings of this research indicated that infestation of cattle with Hypoderma bovis and Hypoderma lineatum is present in Sarab region and the more suitable time for destroying hypoderma larvae in this region is an early autumn of each year.
