Studies on the host preferences of Culicoides imicola, the vector of bluetongue virus in South Africa, are reviewed. There is agreement that this species prefers to feed on cattle but will also feed on other bovidae and sheep. Over a seven year period cattle kept near sheep on a Natal farm appear to have appreciably reduced the incidence of bluetongue in the sheep. In addition to immunization this "decoy" approach is therefore recommended to assist in the protection of stock from insect borne diseases such as bluetongue and possibly African horsesickness and Rift Valley fever.
本文综述了南非蓝舌病病毒传播媒介——库蠓的宿主偏好研究。人们一致认为，该物种更喜欢吸食牛血，但也会吸食其他牛科动物和绵羊的血液。在纳塔尔省的一个农场，七年期间将牛与绵羊饲养在一起，似乎显著降低了绵羊蓝舌病的发病率。因此，除了免疫接种外，建议采用这种“诱饵”方法来帮助保护牲畜免受蓝舌病、可能还有非洲马瘟和裂谷热等虫媒疾病的侵害。
