| 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 |
| 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 |
| 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 |
| 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 |
| 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 |
| 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 |
