Risk analysis of pathogens transmitted by Culicoides (Diptera; Ceratopogonidae) depends on the ability to detect all potential vectors attacking livestock in an area. Onderstepoort 220-V ultraviolet (UV) down-draught light traps are considered the gold standard for this purpose. To improve the flexibility of this trap in the field, in the absence of 220-V power, the possibility of using low-energy light emitting diodes (LEDs) was assessed. The efficiency of a standard 220-V Onderstepoort trap (30 cm 8 W fluorescent UV light tube) was compared to that of 220-V Onderstepoort traps fitted with either two, four or eight individual white LEDs. The Onderstepoort 220-V trap was also compared to a 12-V Onderstepoort trap fitted with an 8 W fluorescent UV light tube, a 12-V Onderstepoort trap with 12 individual white LEDs and 12-V and 220-V Onderstepoort traps fitted with 12 individual UV LEDs. Higher numbers of Culicoides as well as species diversity were collected with a brighter light source. The use of UV LEDs in both the 12-V and 220-V combinations was comparable to the Onderstepoort 220-V light trap with ration to species diversity collected. The Onderstepoort 220-V light trap is recommended if large numbers of Culicoides need to be collected.
媒介昆虫（双翅目：蠓科）传播病原体的风险分析取决于是否能够在一个地区检测到所有潜在的攻击牲畜的媒介。Onderstepoort 220-V 紫外线（UV）下气流诱捕灯被认为是达到这一目的黄金标准。为了提高该诱捕器在野外的灵活性，在没有 220-V 电源的情况下，评估了使用低能量发光二极管（LED）的可能性。标准的 220-V Onderstepoort 诱捕器（30 厘米 8 瓦荧光 UV 灯管）的效率与配备两个、四个或八个单独白色 LED 的 220-V Onderstepoort 诱捕器的效率进行了比较。Onderstepoort 220-V 诱捕器还与配备 8 瓦荧光 UV 灯管的 12-V Onderstepoort 诱捕器、配备 12 个单独白色 LED 的 12-V Onderstepoort 诱捕器、配备 12 个单独 UV LED 的 12-V 和 220-V Onderstepoort 诱捕器进行了比较。使用更亮的光源可以收集到更多的蠓虫以及更多的物种多样性。在 12-V 和 220-V 组合中使用 UV LED 的效果与 Onderstepoort 220-V 诱捕器相当，在收集的物种多样性方面也是如此。如果需要收集大量的蠓虫，则推荐使用 Onderstepoort 220-V 诱捕器。
