初夏，荷兰的一个奶牛场使用拴在牧场上的牲畜对库蠓（双翅目：Ceratopogonidae）的宿主偏好和攻击率进行了量化。在连续七小时（17:00-23:00）内，每小时从一头奶牛、一匹设得兰小马和一头羊身上吸出蠓，相应地产生了十七种、十三种和九种。在获得的 14,181 只蠓中，大约 95% 属于 C. obsoletus 复合体、C. dewulfi、C. chiopterus 和 C. punctatus，它们一起包括欧洲西北部牲畜中所有已证实或潜在的虫媒病毒疾病媒介。平均而言，从牛和设得兰小马身上采集到的库蠓数量分别是从羊身上采集到的库蠓数量的 7.6 倍和 3.5 倍。按丰度降序排列，C. obsoletus 复合体、C. dewulfi 和 C. chiopterus 主导了对所有三种宿主的攻击，而 C. punctatus 和 C. pulicaris 仅偏爱两种较大的宿主。无论所涉及的宿主物种如何，这三个身体区域都吸引了相同的组成物种，C. chiopterus 喜欢腿部，C. punctatus 和 C. achrayi 喜欢腹部，C. obsoletus 复合体、C. dewulfi 和 C. pulicaris 喜欢头部、背部和侧面。已知和潜在的动物疾病媒介不加区别地以多种哺乳动物宿主为食，这意味着包括马在内的所有主要牲畜物种都对一种或多种库蠓传播的病原体敏感。
Culicoides (Diptera: Ceratopogonidae) host preferences and attack rates were quantified in early summer at a dairy farm in the Netherlands using livestock tethered at pasture. Midges were aspirated hourly over seven consecutive hours (17:00-23:00) from a dairy cow, a Shetland pony, and a sheep and correspondingly yielded seventeen, thirteen, and nine species. Of the 14,181 midges obtained, approximately 95% belonged to the C. obsoletus complex, C. dewulfi, C. chiopterus, and C. punctatus that together include all proven or potential vectors for arboviral diseases in livestock in northwestern Europe. On average, 7.6 and 3.5 times more Culicoides were collected, respectively, from the cow and the Shetland pony than from the sheep. In descending order of abundance, the C. obsoletus complex, C. dewulfi, and C. chiopterus dominated attacks on all three hosts, whereas C. punctatus and C. pulicaris favored only the two larger hosts. Irrespective of the host species involved, the three body regions attracted the same component species, C. chiopterus favoring the legs, C. punctatus and C. achrayi the belly, and the C. obsoletus complex, C. dewulfi, and C. pulicaris the head, back, and flanks. That known and potential vectors for animal diseases feed indiscriminately on a broad range of mammal hosts means that all major livestock species, including equines, are rendered susceptible to one or more Culicoides-borne pathogens.
