在日落附近，通过直接从西班牙东北部的绵羊身上吸吸来收集库蠓属（双翅目 Ceratopogonidae）中的叮蠓，以确定特定物种的叮咬、比率和黄昏活动。同一时期还通过紫外线诱饵光诱捕器和二氧化碳诱饵诱捕器收集了蠓，以使用这些常见的监测方法将物种多样性和丰度与实际的绵羊攻击率进行比较。从绵羊身上吸出的库蠓包括 C. obsoletus、C. parroti、C. scoticus、C. punctatus 和 C. imicola。在对两种最常采集的物种（C. obsoletus 和 C. parroti）进行检查的时间段内，峰值寄主搜寻活动发生在日落之前，活动在日落后 1 小时内停止。日落时分，两个物种的宿主攻击率平均为 0.9 只/分钟，其中 C. obsoletus 的最大攻击率为 3/min，C. parroti 的最大攻击率为 4/min。对于这两个物种，从羊身上收集的蠓中大约有 35% 被吸饱。由于 C. obsoletus 的最大叮咬率为 1.1/min，C. parroti 的最大叮咬率为 1.5/min，因此，与其他收集方法相比，用 CO2 诱饵的陷阱收集到的每个物种的蠓数量较少。用紫外线作为诱饵的诱捕器可以很好地指示物种丰富度，但显着低估了 C. obsoletus 和 C. parroti 的宿主攻击率，同时高估了 C. imicola 的宿主攻击率。动物诱饵收集对于解释用于监测蓝舌病毒和非洲马瘟病毒蚊媒的光诱收集的流行病学意义至关重要。
Biting midges in the genus Culicoides (Diptera Ceratopogonidae) were collected near Sunset by direct aspiration from sheep in northeastern Spain to determine species-specific biting, rates and crepuscular activity. Midges were also collected by UV-baited light traps and CO2-baited traps over the same period to compare species diversity and abundance using these common surveillance Methods to actual sheep attack rates. Culicoides aspirated from sheep included C. obsoletus, C. parroti, C. scoticus, C. punctatus, and C. imicola. Peak host-seeking activity during the time period examined for the two most commonly collected Species (C. obsoletus and C. parroti) occured just before sunset and activity ceased within 1 h after sunset. Host attack rates near sunset averaged 0.9 midges/min for both species with maximum attack rates of 3/min for C. obsoletus and 4/min for C. parroti. For both species, approximate to 35% of midges collected from the sheep were engorged. giving it maximum biting rate of 1.1/min for C. obsoletus and 1.5/min for C. parroti, Traps baited with CO2 collected fewer midges of each Species relative to Other collection methods. Traps baited with UV light provided it good indication of species richness but significantly underestimated the host attack rate of C. obsoletus and C. parroti while overestimating the host attack Late of C. imicola. Animal-baited collecting is critical to interpret the epidemiological significance of light trap collections used for surveillance of the midge vectors of bluetongue virus and African horse sickness virus.
