(Diptera, Ceratopogonidae) are small biting midges and are known as vectors for many arboviruses, including bluetongue virus (BTV) and epizootic hemorrhagic disease virus (EHDV). Tengchong County of Yunnan Province, China, which borders Myanmar, has many private farms with goats, sheep, and cattle. To estimate the risk of -borne viral diseases such as bluetongue (BT) and epizootic hemorrhagic disease (EHD) in this area, an investigation of the diversity and abundance of in Tengchong between May 2024 and April 2025 was performed. As a result, 70 collections totaling approximately 93,000 were carried out at five farms (cattle + Asian buffaloes, goats, and sheep, respectively). Nineteen species were identified, and eight potential cryptic species were found. A total of 13 sequences and 4 sequences for 13 specimens were generated. The most dominant species were Obsoletus (44.1%), (23.3%), and (12.9%) at the bovine farm; (68.0%), (12.6%), and (Asia) (6.3%) at the goat farm; and (73.6%), (7.3%), and sp. nr (6.3%) at the sheep farm. In this investigation, , Obsoletus, and were the most dominant potential BTV vectors, and the period between July and October may be the main period for epidemics of -borne viruses in Tengchong.
蠓科（双翅目，蠓科）是小型吸血蠓，是包括蓝舌病毒（BTV）和流行性出血病病毒（EHDV）在内的许多虫媒病毒的传播媒介。中国云南省腾冲县与缅甸接壤，有许多饲养山羊、绵羊和牛的私人农场。为了评估该地区蓝舌病（BT）和流行性出血病（EHD）等同种传播的病毒性疾病的风险，于2024年5月至2025年4月对腾冲的蠓的多样性和丰度进行了调查。结果，在五个农场（分别为牛+亚洲水牛、山羊和绵羊）共进行了70次采集，总计约93,000只蠓。鉴定出19个物种，并发现了8个潜在的隐存物种。共生成了13个标本的13条蠓序列和4条其他序列。在养牛场，最主要的物种是废弃蠓（44.1%）、某蠓（23.3%）和澳蠓（12.9%）；在山羊场，是某蠓（68.0%）、某蠓（12.6%）和亚洲某蠓（6.3%）；在绵羊场，是某蠓（73.6%）、某蠓（7.3%）和近缘某蠓（6.3%）。在本次调查中，某蠓、废弃蠓和澳蠓是最主要的潜在BTV传播媒介，7月至10月期间可能是腾冲虫媒病毒流行的主要时期。
