中文摘要	目的对普氏野马野化种群和圈养种群进行驱虫,研究不同生存条件下普氏野马感染马胃蝇的多样性和感染特点。方法于2015年1月进行野马驱虫保健工作,对野马群驱虫采用随机抽样、对野马个体采用全程采集粪便中的马胃蝇幼虫。结果保护区内野马在排虫高峰期粪便平均排虫(140.862.8)只/堆,同期野马中心圈养野马平均排虫(1.80.9)只/堆,两者差异有统计学意义(u=-4.997,P=0.000),显示野马中心周边的马科动物隔离区和专供饲草可有效降低马胃蝇蛆病的感染;于保护区内采集马胃蝇5 357只,经鉴定为黑腹胃蝇、鼻胃蝇、黑角胃蝇、肠胃蝇和红尾胃蝇,其中黑腹胃蝇(96.84%)为优势种;野马中心采集马胃蝇83只,鉴定为肠胃蝇、红尾胃蝇、鼻胃蝇、黑角胃蝇和裸节胃蝇,肠胃蝇(48.19%)为优势种,红尾胃蝇(39.76%)次之,在野马中心未发现黑腹胃蝇,说明其基于食草的传播链被切断,两者物种构成存在差异;马胃蝇多样性指数和均匀度显示不同生存条件下野马感染马胃蝇的多样性差异明显,保护区马胃蝇区系处于极端状态。结论同处于准噶尔盆地的保护区和野马中心,野马生活环境的异质性使马胃蝇感染特点分明,黑腹胃蝇在干旱荒漠草原有极强的适应性。
英文摘要	Objective A parasitological survey was conducted in wild and captive populations of Equus przewalskii with treatment of antiparasitics to investigate the infection, diversity and parasitic characteristics of Gasterophilus spp. in E. przewalskii which lives in different conditions. Methods Gasterophilus spp. larvae were collected and counted from the random fecal samples of E. przewalskii populations and all the fecal samples of E. przewalskii individuals after antiparasitic treatment in January 2015. Results There was a statistically significant difference in the mean number of Gasterophilus spp. larvae at the peak of larvae expelled between wild and captive populations (140.862.8 and 1.80.9, respectively) (u=-4.997,P=0.000). Larval burdens of captive population were reduced by establishing isolated zone and providing special forage grasses. A total of 5 357 larvae were collected from wild population, which were identified as the following 5 species of Gasterophilus spp.: G. pecorum, G. nasalis, G. nigricornis, G. intestinalis and G. haemorrhoidalis. Gasterophilus pecorum (96.84%) was the predominant species in the wild population. In total 83 larvae were collected from captive population, and 5 species of Gasterophilus spp. were identified as follows: G. intestinalis, G. haemorrhoidalis, G. nasalis, G. nigricornis, and G. inermis. The prevailing species were G. intestinalis (48.19%) and G. haemorrhoidalis (39.76%). There was an obvious difference between wild and captive population in species composition of Gasterophilus. Shannon-Wiener index of Gasterophilus spp. was 1.07 in the captive population, significantly higher than the wild one(0.17). The evenness index of Gasterophilus spp. was higher in the captive population (0.66) similarly, while it was 0.10 in the wild population. The results shown a striking difference of Gasterophilus spp. diversity between wild and captive populations, while the latter was rigorous infected by horse gastrointestinal myiasis. Gasterophilus pecorum was the predominant species in the wild population while it was absent in the captive population, which indicated that unique transmission cycle with grass was intyerrupted. Conclusion Equus przewalskii populations in different living environments have distinctly different infective charsacteristics of Gasterophilus spp., G. pecorum has extremely strong adaptability to the desert steppe.
