Culicoides biting midges (Diptera: Ceratopogonidae) are vectors of a range of orbiviruses that cause important veterinary diseases such as bluetongue and African horse sickness. The effective monitoring of Culicoides species diversity and abundance, both at livestock and near potential wildlife hosts, is essential for risk management. The Onderstepoort 220-V ultraviolet (UV) light trap is extensively used for this purpose. Reducing its power requirements by fitting low-energy light-emitting diodes (LEDs) can lead to greater flexibility in monitoring. A comparison of the efficiency of the 220-V Onderstepoort trap (8-W fluorescent UV light) with the efficiency of the 220-V or 12-V Onderstepoort traps fitted with red, white, blue or green LEDs or a 12-V fluorescent Onderstepoort trap demonstrated the 220-V Onderstepoort trap to be the most efficient. All the results showed nulliparous Culicoides imicola Kieffer females to be the dominant grouping. Despite the lower numbers collected, 12-V traps can be used in field situations to determine the most abundant species.
库蠓（双翅目：蠓科）是多种环状病毒的传播媒介，这些病毒会引发重要的兽医疾病，如蓝舌病和非洲马瘟。对家畜及潜在野生动物宿主附近的库蠓物种多样性和数量进行有效监测，对风险管理至关重要。翁德斯普特220伏紫外线诱捕器广泛用于此目的。通过安装低能耗发光二极管（LED）降低其电力需求，可使监测更具灵活性。将220伏翁德斯普特诱捕器（8瓦荧光紫外线灯）与配备红色、白色、蓝色或绿色LED的220伏或12伏翁德斯普特诱捕器或12伏荧光翁德斯普特诱捕器的效率进行比较，结果表明220伏翁德斯普特诱捕器效率最高。所有结果显示，未产卵的库蠓雌性个体为优势群体。尽管捕获数量较少，但12伏诱捕器可用于野外情况，以确定数量最多的物种。
