Culicoides biting midges (Diptera: Ceratopogonidae) are hematophagous arthropod vectors that transmit epizootic arthropod-borne viruses (arboviruses). Arboviruses are recognized as causes of pregnancy loss, encephalomyelitis, and congenital malformations in ruminants. Therefore, continuous monitoring and control of Culicoides, which causes significant damage to industrial animals are necessary. We performed attraction and repellent tests in Culicoides using various essential oils, cow dung, and carbon dioxide (CO2). Culicoides tended to move more to cow dung (60.8%, P<0.0001) and CO2 (63.8%, P<0.01). To the essential oils as repellents, 26.1% (P<0.0001), 18.7% (P<0.001), and 25.5% (P<0.01) of the Culicoides moved to the lavender, lemongrass, and eucalyptus chamber, respectively. The Culicoides that moved to the 3 essential oils chambers showed markedly low activity. Collectively, it was showed that Culicoides tended to be attractive to cow dung and CO2, and repellent from the 3 essential oils.
厩蠓（双翅目：蠓科）是吸血节肢动物媒介，传播虫媒病毒（arboviruses）。虫媒病毒被认为是反刍动物流产、脑脊髓炎和先天性畸形的原因。因此，对厩蠓进行持续监测和控制是必要的，因为它会对工业动物造成严重损害。我们使用各种精油、牛粪和二氧化碳（CO2）对厩蠓进行了吸引和驱避测试。厩蠓更倾向于向牛粪（60.8%，P<0.0001）和 CO2（63.8%，P<0.01）移动。作为驱避剂，26.1%（P<0.0001）、18.7%（P<0.001）和 25.5%（P<0.01）的厩蠓分别移动到薰衣草、柠檬草和桉树室。移动到 3 种精油室的厩蠓表现出明显的低活性。总的来说，厩蠓倾向于被牛粪和 CO2 吸引，而被 3 种精油驱避。
