Aim:  This study aimed to determine the prevalence of  Oestrus   ovis  in sheep meant for meat commercialization in the main slaughterhouse of the country.    Materials and Methods:  Between October 2015 and December 2015, we assessed the occurrence of  Oestrus  myiasis in the main slaughterhouse localized in Quito. In total, 80 sheep heads were randomly inspected and necropsied. Larvae were removed from nasal cavities and paranasal sinuses and cleaned. ANOVA (generalized linear model) was used to estimate the relationship between sex, age, and place of origin and presence or absence of parasite larvae.    Results:  Morphological identification confirmed that 19% (15/80) of the examined animals were positive for  Oestrus ovis ; from the positive cases, 21% were young animals <12 months old. We found that statistical differences by animal sex, males, were most infested 93% (14/15) than females 7% (1/15). Larvae’s L2 were more abundant than other stages (62 of the total 149). 14 of the infested animals were from the Andean places at > 2500 meters above sea level (m.a.s.l.), and only one case from the coastal region at 250 m.a.s.l. with tropical environmental conditions.    Conclusions:  Our results showed evidence of the presence of myiasis caused by  O. ovis  in Andean and coastal places in Ecuador and its adaptation to different environmental conditions from that reported previously in temperate regions from Europe and Africa.
