Eleven (9.82%) Arabian horses were found to be infected by larvae of Gasterophilus spp. A total of 409 third stage larvae (L3) were collected from fecal samples. In the Sanliurfa region, the prevalence of three species of Gasterophilus was identified as follows: Gasterophilus intestinalis (6.25%), G. nasalis (2.67%) and G. pecorum (0.89%).
