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 ...200010701560
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 ...19938331487
