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
water use patterns of sympatric przewalski's horse and khulan: interspecific comparison reveals niche differences.acquiring water is essential for all animals, but doing so is most challenging for desert-living animals. recently przewalski's horse has been reintroduced to the desert area in china where the last wild surviving member of the species was seen before it vanished from china in the 1960s. its reintroduction placed it within the range of a close evolutionary relative, the con-generic khulan. determining whether or not these two species experience competition and whether or not such competition was ...201526161909
identification of equine influenza virus infection in asian wild horses (equus przewalskii).an outbreak of equine influenza was observed in the asian wild horse population in xinjiang province, china, in 2007. nasal swabs were collected from wild horses and inoculated into 9-10-day spf embryonated eggs. the complete genome of the isolate was sequenced. a comparison of the amino acid sequence revealed that the isolate was an equine influenza virus strain, which we named a/equine/xinjiang/4/2007. each gene of the virus was found to have greater than 99 % homology to equine influenza viru ...201424212887
oviposition site selection by gasterophilus pecorum (diptera: gasterophilidae) in its habitat in kalamaili nature reserve, xinjiang, china.oviposition site selection is an important aspect of the behavioural ecology of insects. a comparison of the habitats used by a species enhances our understanding of their adaptation to altered environments. we collected data on the oviposition behaviours of gasterophilus pecorum (diptera: gasterophilidae) in its habitat in kalamaili nature reserve (knr), xinjiang, china between march and october 2014. we found 91 quadrats were used by g. pecorum for oviposition. examining 13 ecological factors ...201526621549
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
