| corrected misidentification of first instars of the bot flies cephenemyia apicata and c. jellisoni, with a review of the biology and life history of both species. | first instars obtained from the uteri of host-seeking females, and compared with previously published descriptions of larvae collected from columbian black-tailed deer (odocoileus hemionus columbianus), revealed that larvae described as cephenemyia apicata bennett & sabrosky (diptera: oestridae) actually are c. jellisoni townsend. several new characters are added to supplement the original descriptions of the first instars of these species. collections of all larvae from deer autopsied during di ... | 2011 | 22168389 |
| long-term epidemiology, effect on body condition and interspecific interactions of concomitant infection by nasopharyngeal bot fly larvae (cephenemyia auribarbis and pharyngomyia picta, oestridae) in a population of iberian red deer (cervus elaphus hispanicus). | we studied the pattern of infection and the inter-annual variation and individual factors affecting the infection of 2 species of nasopharyngeal bot flies, cephenemyia auribarbis and pharyngomyia picta (diptera: oestridae), in a population of iberian red deer (cervus elaphus hispanicus) from south central spain (10 annual periods between 1990 and 2003). mean prevalence+/-s.e.95%ci of infection was 35.19+/-4.24% (n=486). the frequency distribution of the parasites was markedly aggregated (k: 0.21 ... | 2004 | 15471010 |

| pharyngeal bot flies in cervus elaphus in central spain: prevalence and population dynamics. | the prevalence and intensity of infestations by bot flies pharyngomyia picta and cephenemyia auribarbis in red deer (cervus elaphus) from quintos de mora (toledo, spain) were determined over a 1-yr period. bots were present all year. no clear correlations were found between age or sex of the host and parasitization levels (prevalence and intensity). considerable variation was found in prevalence and intensity, with larger values from december to march. cephenemyia auribarbis was restricted from ... | 2000 | 10701560 |
| oestrosis in red deer from spain. | a survey of naso-pharyngeal myiasis affecting red deer (cervus elaphus) in southern spain was conducted. the parasites involved were the larvae of pharyngomyia picta and cephenemyia auribarbis (diptera:oestridae), which coexist sympatrically within this host. males and older animals had higher prevalences and intensities of fly larvae. differences in behaviour and habitat use by male and female deer, and the increase of head size in older males are possibly responsible for this. there were low d ... | 1998 | 9813856 |
| occurrence and overlapping of pharyngeal bot flies pharyngomyia picta and cephenemyia auribarbis (oestridae) in red deer of southern spain. | from 1985 to 1990, 372 red deer (cervus elaphus) from southern spain were examined for larvae of pharyngeal bot flies pharyngomyia picta and cephenemyia auribarbis. the infestation was related to age, sex and intensity of infection. fawns and adult deer (more than 5 years old) had a significantly (p < 0.05) higher prevalence and intensity of infection than younger deer. conversely, no significant difference has been noted between sexes. ninety percent of deer were found to be infested. a simulta ... | 1993 | 8493758 |
| pharyngeal bot flies (oestridae) from sympatric wild cervids in southern spain. | the prevalence of 2 species of pharyngeal bot flies parasitizing sympatric wild ungulates from southern spain is given. pharyngomyia picta was found in all red deer and fallow deer whereas cephenemyia auribarbis was found in 59% of fallow deer and 81% of red deer examined. the mean number of p. picta larvae was 3-6 times more than that of c. auribarbis larvae. these data suggest that red deer are more heavily parasitized than fallow deer and that they are predominantly infested with p. picta lar ... | 1993 | 8331487 |
| morphological and molecular identification of nasopharyngeal bot fly larvae infesting red deer (cervus elaphus) in austria. | nasopharyngeal myiases are caused by larvae of bot flies (diptera: oestridae), which have evolved a high specificity for their hosts. bot flies (n = 916) were collected from 137 (57.6 %) out of 238 red deer (cervus elaphus) hunted in vorarlberg and tyrol (western austria). after being stored in 75 % ethanol, larvae were identified to species level and developmental stage using morphological and morphometric keys. larvae were also molecularly characterized by polymerase chain reaction (pcr) ampli ... | 2016 | 27492199 |
| [treatment of oestriasis and hypodermosis in red deer (cervus elaphus hippelaphus) and roe deer (capreolus c. capreolus) with ivermectin (ivomec)]. | in two test areas in austria (burgenland, lower austria) ivermectin has been used to control oestrinosis and hypodermosis in red- and roe deer since many years (1985 and 1987, respectively). the results until 1992, using the injectable solution ivomec-injection 1% only, have been reported (kutzer, 1994). in continuation of these tests ivomec-praemix 0.6% was examined and it turned out that the treatment was extremely successful. in practice ivomec-praemix 0.6% has to be given preference due to i ... | 2000 | 10816915 |
| first record in south asia of deer throat bot fly larvae pharyngomyia picta (meigen, 1824) (diptera: oesteridae) from sambar deer (rusa unicolor), a new host record. | the bot fly larvae, identified to be the third instars of the deer throat bot fly pharyngomyia picta were recovered from the lumen of trachea and secondary bronchi during the necropsy of a female sambar deer (rusa unicolor) in kerala, india. this forms the first report of p. picta from india and the whole of south asia. sambar deer is a new host record for the larvae of this fly. morphological description of the third stage larvae with supporting figures are presented. | 2012 | 22735848 |
| ultramorphological and molecular characteristics of the larval stages of the horse nasal-myiasis fly, rhinoestrus sp. (diptera: oestridae) from mongolian horse in china. | rhinoestrus sp. (diptera: oestridae) is an economically important parasite that can cause severe nasal myiasis in equids and can also affect humans. the ultrastructure of all rhinoestrus sp. larval instars from mongolian horse was examined by light and scanning electron microscopy to characterize the features of rhinoestrus. the structure of the anterior region, posterior region, and the spines of the third segment was analyzed for 10 specimens in each larval stage. additionally, 34 third-instar ... | 2018 | 29115038 |
