Abstract: Objective To investigate the characteristics of hypodermosis in rodents in the border areas between China and Mongolia in Junggar basin, and to provide a basis for the prevention and control of zoonotic myiasis. Methods From 2019 to 2020, the one-day bow-shaped clamp trap method was used to catch rodents in the border areas of China-Mongolia ports in Junggar basin. The rodents were inspected to collect ecto- and endoparasites. Morphological methods were used to identify the species of maggot larvae. An analysis was performed on the epidemic characteristics and risk warning of hypodermosis in Citellus undulatus. Results In the border areas of Hongshanzui and Takeshiken China-Mongolia ports, 339 rodents were caught, among which 49 were infected with hypodermosis. Among the 21 Clethrionomys rutilus rodents, 2 (9.52%) were infected with the first instar maggot larvae. Among the 318 C. undulates rodents, 47 (14.78%) were infected with hypodermosis. A total of 102 maggot larvae in various stages were collected from C. undulates, with an infection intensity of 2.17. The maggots appeared in June, peaked in July and August, and disappeared at the end of September. They parasitized mainly on the abdomen and roots of the limbs of rodents, and a few were subcutaneous on the back. The pathogen of hypodermosis that infected C. undulates was identified as the third instar maggot larvae of Oestroderma schubini, (Diptera: Hypodermatidae). Conclusion Hypodermosis is first recorded in C. undulatus in the border areas between China and Mongolia in Junggar basin, and this is of important practical significance for the monitoring of zoonotic myiasis and the early warning of the transmission risk of pathogenic flies.

摘要: 目的 了解准噶尔中国-蒙古国(中蒙)边境区鼠类皮蝇蛆感染特点,为防控人兽共患蝇蛆病传播提供依据。方法 2019-2020年在准噶尔中蒙口岸边境线区用一日弓形夹法捕鼠,检查并采集体内外寄生虫,用形态学方法鉴定皮蝇蛆幼虫,分析长尾黄鼠皮蝇蛆病流行特点及风险预警。结果 在中蒙红山嘴、塔克什肯边境线区,339只鼠类中有49只感染皮蝇蛆,其中21只红背䶄中有2只感染皮蝇1龄幼虫,感染率为9.52%;318只长尾黄鼠中有47只感染皮蝇蛆,感染率为14.78%。在长尾黄鼠体表采集各期蝇幼虫102只,感染强度为2.17。皮蝇蛆在6月出现,7-8月为侵袭高峰,9月末消失。皮蝇蛆主要寄生于宿主腹部和四肢根部,少数在背部皮下。感染长尾黄鼠蝇蛆病原鉴定为双翅目皮蝇科狂皮蝇属平颜狂皮蝇(Oestroderma schubini)的3龄幼虫。结论 在准噶尔中蒙边境线区首次发现长尾黄鼠皮蝇蛆病,对监控人兽共患蝇蛆病及致病蝇种传播风险预警都具有重要的现实意义。
