The light trap is an important tool to determine the presence and abundance of vectors in the field. However, no one has studied the efficiency of light traps for collecting Culicoides in Thailand. In the present study, the efficacy of four light sources was evaluated in Prachuap Khiri Khan province, Thailand. Incandescent (INCND) light, white fluorescent (WHT-FLR) light, ultraviolet fluorescent (UV-FLR) light, and UV light-emitting diode (UV-LED) light were tested using commercial traps. In total, 30,866 individuals of Culicoides species were collected from November 2020 to June 2021, of which 21,016 were trapped on site 1 and 6,731 were trapped on site 2. The two most abundant Culicoides species were C. imicola (54%) and C. oxystoma (31.2%). UV-FLR was highly effective, followed by UV-LED light, WHT-FLR light, and INCND light, respectively, for Culicoides collection. Significantly, more Culicoides species were collected in those traps baited with UV-FLR light, UV-LED light, or WHT-FLR light than for INCND light traps. Traps equipped with UV-FLR lights can be recommended to trap Culcoides biting midges for monitoring purposes.
诱虫灯是确定现场病媒昆虫存在和丰度的重要工具。然而，目前尚未有人研究过诱虫灯在泰国收集类库蠓的效率。本研究评估了在泰国巴蜀府使用的四种光源的效果。使用商业诱虫灯对白炽（INCND）灯、白色荧光（WHT-FLR）灯、紫外线荧光（UV-FLR）灯和紫外线发光二极管（UV-LED）灯进行了测试。共从 2020 年 11 月至 2021 年 6 月收集了 30866 只类库蠓，其中 21016 只在现场 1 和现场 2 捕获，6731 只在现场 1 和现场 2 捕获。两种最丰富的类库蠓物种是 C. imicola（54%）和 C. oxystoma（31.2%）。UV-FLR 的效果最佳，其次是 UV-LED 灯、WHT-FLR 灯和 INCND 灯，分别用于收集类库蠓。重要的是，与 INCND 诱虫灯相比，用 UV-FLR 灯、UV-LED 灯或 WHT-FLR 灯诱捕的类库蠓种类更多。建议使用配备 UV-FLR 灯的诱虫灯来监测类库蠓叮咬性蚊虫。
