Oviposition site selection by Gasterophilus pecorum (Diptera: Gasterophilidae) in its habitat in Kalamaili Nature Reserve, Xinjiang, China.
Bottom Line: We found 91 quadrats were used by G. pecorum for oviposition.G. pecorum often selected sites at a distance < 2000 m from a water source and average altitude 900-1000 m.The oviposition site selection by G. pecorum may be correlated with the behaviour of Przewalski's horses (Equus ferus przewalskii), and water and food resources may strongly influence oviposition site selection, as Przewalski's horses rest and forage in these areas.

Mentions: The two horse groups used seasonal and permanent water sources (Fig. 1). The greatest distance from an oviposition site to the nearest water source was <500 m (46/91). Table 2 shows that G. pecorum preferred semi-sunny and semi-cloudy slopes, higher and lower slope positions, and slopes of 10–30°. It preferred total plants < 10% and Stipa capillata coverage < 10% in the lower slopes, but Ceratoides latens coverage in higher and intermediate slopes. In the lower slope habitat, the numbers of plant species and families was < 5. Oviposition sites were often near a water source with a distance < 2000 m and average altitude of 900–1000 m. Table 2 presents the frequency distribution of different habitat factors. Most oviposition sites (66/91) were found within 20 m of the nearest path used by equids.
