Despite some limitations suction light traps are the primary tools used for the collection of Culicoides species (Diptera: Ceratopogonidae). The range of attraction of the Onderstepoort light trap is not known but an insight into the range of a trap will determine where the trap must be positioned relative to the hosts present, possible breeding sites and environmental structures in the trapping vicinity. It will therefore contribute to a more meaningful interpretation and comparison of results between trapping events. In the present study the number of Culicoides midges collected in a single trap was compared to those of traps made with an additional trap respectively 1m, 4m and 8.5m away from the first. Treatments between sites were rotated in three replicates of a 4×4 Latin square design. While interactions were found in traps 4m apart no statistically significant interactions were found when they were 8.5m apart. The range of attraction, indicated by the interaction between two traps, will be between 2m and 4m. In interpreting light trap results the limitations of this collection method needs to be taken into consideration.
尽管存在一些限制，但吸虫光陷阱仍然是收集库蠓属物种（双翅目：蠓科）的主要工具。Onderstepoort 光陷阱的吸引力范围尚不清楚，但对陷阱范围的了解将决定陷阱相对于存在的宿主、可能的繁殖地点和附近环境结构的位置。因此，这将有助于对诱捕事件之间的结果进行更有意义的解释和比较。在本研究中，将一个单一陷阱中收集的库蠓数量与距离第一个陷阱分别为 1m、4m 和 8.5m 的附加陷阱中收集的库蠓数量进行了比较。在 4x4 拉丁方设计的三个重复中，站点之间的处理是轮换的。虽然在相距 4m 的陷阱中发现了相互作用，但在相距 8.5m 的陷阱中没有发现统计学上显著的相互作用。两个陷阱之间相互作用所指示的吸引力范围将在 2m 和 4m 之间。在解释光陷阱结果时，需要考虑到这种收集方法的局限性。
