Culicoides brevitarsis transmits important ruminant arboviruses, such as Akabane, Aino and bluetongue viruses. The presence of this species has so far been recognized primarily in Okinawa, the southernmost prefecture of Japan. In entomological surveys in 2008 and 2009, C. brevitarsis was collected at 8 sites throughout Nagasaki, Kumamoto and Kagoshima Prefectures. The collection sites are all located near pastures, where the larvae of C. brevitarsis can grow in cattle dung left in the field. C. brevitarsis was confirmed at the same sites in two consecutive years, suggesting that it overwinters in Kyushu. Given the risk of arbovirus transmission, the ecology of C. brevitarsis in Japan, such as its distribution range, seasonal abundance and larval breeding sites, should be investigated in more detail.
短角库蠓传播重要的反刍动物虫媒病毒，如赤羽病毒、爱诺病毒和蓝舌病毒。到目前为止，该物种主要在日本最南端的冲绳县被发现。在2008年和2009年的昆虫学调查中，短角库蠓在长崎、熊本和鹿儿岛县的8个地点被采集到。采集地点均位于牧场附近，短角库蠓的幼虫可以在留在田间的牛粪中生长。短角库蠓在连续两年的同一地点被证实存在，这表明它在九州越冬。鉴于虫媒病毒传播的风险，应更详细地调查短角库蠓在日本的生态，如分布范围、季节丰度和幼虫繁殖地。
