population genetic structure of gasterophilus pecorum in the kalamaili nature reserve, xinjiang, based on mitochondrial cytochrome oxidase (coi) gene sequence.gasterophilosis is a significant threat to equids in the desert steppe of xinjiang, china, where gasterophilus pecorum (fabricius) (diptera: gasterophilidae) is the dominant botfly species. a population analysis was conducted on 195 individual g. pecorum larvae from three host species, przewalski's horse, the domestic horse and the asiatic wild ass. the distribution of haplotypes of the maternally inherited mitochondrial cytochrome oxidase subunit i (coi) gene was analysed to assess the populati ...201425171609
human activity dampens the benefits of group size on vigilance in khulan (equus hemionus) in western china.animals receive anti-predator benefits from social behavior. as part of a group, individuals spend less time being vigilant, and vigilance decreases with increasing group size. this phenomenon, called "the many-eyes effect", together with the "encounter dilution effect", is considered among the most important factors determining individual vigilance behavior. however, in addition to group size, other social and environmental factors also influence the degree of vigilance, including disturbance f ...201626756993
the incidence and species composition of gasterophilus (diptera, gasterophilidae) causing equine myiasis in northern xinjiang, china.a survey was conducted on the detection of the larval gasterophilus species in 90 equines via necropsy or after administering oral ivermectin in xinjian, china, from 2008 to 2013. all 90 (100%) equines were infested by larval gasterophilus, and 3723second instar larvae (l2) and 63,778 third instar larvae (l3) were collected from faecal samples and the digestive tract, a ratio of l2:l3=1:17. over 84.45% of the animals contained ≤1500 larvae and 7.78% had >2000 larvae. the highest totals of l2 and ...201626827858
