| external ophthalmomyiasis caused by oestrus ovis. | a 16-year-old white girl presented with a foreign-body sensation in her right eye. seven oestrus ovis maggots were removed with the aid of a cotton wool-tipped probe. the subsequent history has been quite uneventful. this appears to be the fifth reported case of ophthalmomyiasis externa in southern africa. | 1981 | 7302725 |
| the similarity between arrested development in parasitic nematodes and diapause in insects. | the similarities between arrested development in parasitic nematodes and diapause in insects are discussed. particular attention is paid to the similarity between arrested development in haemonchus contortus and diapause in oestrus ovis in sheep. factors inducing arrested development and influencing resumed development and measures to control arrested nematodes in ruminants are discussed. | 1981 | 7341780 |

| ophthalmooestriasis externa. | in this case of ophthalmooestriasis externa in a 20-year-old white male student attending mississippi state university, three first instar larvae from the sheep nasal bot fly, oestrus ovis, were removed. the patient responded well to application of sulfa eye drops. the exact means by which the patient acquired the larvae was not determined. | 1980 | 7434057 |
| ophthalmomyiasis caused by the sheep nasal bot, oestrus ovis (oestridae) larvae, in the benghazi area of eastern libya. | in a two-year study, from january 1977 to december 1978, 80 human cases of ophthalmomyiasis were recorded at the benghazi central eye clinic. infections were due to larvae of the sheep nasal bot, ostrus ovis. the annual incidence was estimated to be 10 per 100,000 population, with most of the cases occurring amongst males during the months of may, june and july. a typical case history is described to illustrate the clinical features and the treatment used. | 1980 | 7434424 |
| influence of constant and variable temperatures on pupal development of the sheep bot fly (oestrus ovis l.). | the paper presents the results obtained in experiments on the influence of constant and variable temperatures on the pupal development of the sheep bot fly oestrus ovis l. the lower thermic threshold of pupal development was established (12.1 degrees c for males, 11.5 degrees c for females). the sum of the effective temperatures necessary for the completion of pupal development was calculated (242.9 +/- 3.0 degree/day for males, 278.8 +/- 3.8 degree/day for females). the long duration of the fem ... | 1980 | 7450614 |
| ophthalmomyiasis externa due to the sheep botfly oestrus ovis (diptera: oestridae) in southwest germany. | we present a case of ophthalmomyiasis externa in a 54-year-old man in southwest germany (baden-württemberg). after the patient had been attacked by a fly, he complained of a foreign-body sensation and itching in his right eye and developed purulent conjunctivitis. slit-lamp examination revealed the presence of translucent, rapidly moving insect larvae in the conjunctival sac and on the corneal surface. following removal of all larvae and instillation of gentamicin, the symptoms completely resolv ... | 1995 | 7663333 |
