A total of 624 sheep, selected at random, were examined and 59% were found to be infested by O. ovis. A total of 8801 larvae were collected, of which 68.9% were first-stage, 19.1% second-stage and 12% third-stage larvae. All three larval stadia were seen in each month of the year. The larval intensity for infected sheep was 23.9, with 16.48 L-1, 4.55 L-2 and 2.87 L-3. The monthly prevalence ranged from 34.6% in January to 76.9% in October. The largest number of larvae (180) was obtained from a sheep in August (122 L1, 52 L 2 and 6 L 3). The infestation rate was higher in 4-6-year-old sheep, at 72.6%. The infestation rates were 64.4% in female and 47.5% in male sheep.en10.1111/j.1365-2915.2006.00632.xinfo:eu-repo/semantics/closedAccessOestrus ovisprevalencesheepTurkeyArticle20334734917044888Q1WOS:000241155500013Q1
