Abstract: 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 using the t-test, chi-square test, and principal component analysis showed that G. pecorum's oviposition habitat was preferentially on slopes with inclinations of 10-30° that were semi-sunny, semi-cloudy slopes, in positions high or low on the slopes, with preferences for total plants lower than 10% and Stipa capillata coverage lower than 10% on the low slopes, but Ceratoides latens coverage on the high and intermediate slopes, when the numbers of plant species and families were lower than five. 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. Le choix du site de ponte est un aspect important de l’écologie comportementale des insectes. Une comparaison des habitats utilisés par une espèce améliore notre compréhension de son adaptation à des environnements modifiés. Nous avons recueilli des données sur les comportements de ponte de (Diptera, Gasterophilidae) dans son habitat dans la Réserve Naturelle Kalamaili (KNR), Xinjiang, Chine, entre mars et Octobre 2014. Nous avons trouvé 91 quadrats qui étaient utilisés par pour la ponte. Un examen de treize facteurs écologiques en utilisant le test , le test du chi carré et une analyse en composantes principales a montré que l’habitat de ponte de était préférentiellement des pentes avec des inclinaisons de 10–30° qui étaient semi-ensoleillées, semi-nuageuses, dans des positions haute ou basse sur les pentes, avec des préférences pour une couverture totale par les plantes inférieure à 10 % et inférieure à 10 % pour sur les pentes basses, et pour une couverture par sur les pentes hautes et intermédiaires où le nombre d’espèces et de familles de plantes étaient inférieur à cinq. sélectionne souvent des sites à une distance inférieure à 2000 m d’une source d’eau et une altitude moyenne de 900–1000 m. Le choix du site de ponte par peut être corrélé avec le comportement des chevaux de Prjevalski (), et les ressources en eau et de nourriture peuvent influer fortement sur le choix du site de ponte, car les chevaux de Prjevalski se reposent et paissent dans ces zones.

This research explores the breeding area choices of a type of fly called Gasterophilus pecorum in Kalamaili Nature Reserve, China. Particularly, the investigators found that specific environmental factors play a crucial role in the fly’s preference for breeding locations.
Objective of the Research
The study aims to understand the oviposition habits — where a female insect chooses to lay her eggs — of the Gasterophilus pecorum (a type of fly) and its adaptation to the environment in the Kalamaili Nature Reserve in Xinjiang, China.
Research Methodology
The research was conducted between March and October of 2014.
Researchers carefully observed and studied the behaviour of these insects and their chosen oviposition sites.
The preference of these flies for certain environments was evaluated based on 13 different ecological factors.
These factors were analyzed using statistical tests such as the t-test, chi-square test, and principal component analysis.
Key Findings
The researchers discovered that G. pecorum preferred to lay eggs on slopes with inclinations between 10-30°. These areas were typically semi-sunny, semi-cloudy, and could be either high or low on the slopes.
The flies had a preference for areas with less than 10% plant coverage, particularly Stipa capillata on the lower slopes and Ceratoides latens on the higher and intermediate slopes.
Moreover, the preferred areas usually had a plant species diversity of less than five.
The flies often picked sites less than 2000m from a water source and at an average altitude of 900-1000m. This may be due to the behaviour of Przewalski’s horses — which are likely hosts or food sources for the flies — that rest and forage in these areas.
The research also indicates that the selection of oviposition sites by G. pecorum might be heavily influenced by resource availability, particularly water and food.
Implications of the Research
This research can enhance each understanding of the behavioural ecology of G. pecorum and contribute to the wider field of insect research.
The findings may also have implications for future management and conservation strategies within the Kalamaili Nature Reserve.
