在一项国家监测计划中使用了带有白炽球的捕光器来检测库蚊的存在。负责将病毒传播给牲畜和本地动物。最近发生的事件表明，应重新考虑并可能改进这些陷阱的效率。随后，在新南威尔士州的两个地点测定了8种库蚊对发光二极管(LED)的反应。褐家库蚊、本鲁伊库蚊和马克库蚊对蓝光有较强的引诱作用。对蓝光和绿光的反应不能分开，对蓝光和绿光的反应不能分离，对蓝光和绿光的反应不能分离。短冠库蚊对绿光有明显的引诱作用。本种是赤潮病毒和蓝舌病毒在澳大利亚的主要传播媒介。这些反应都比目前在捕光器中使用的白炽灯的反应大得多。所有物种对红光的反应都小于对白炽光的反应。绿光LED的发光强度也与短纹夜蛾的捕获量有关。这些比目前使用的白炽球的强度在白炽灯强度的46%到142%之间时更有效。
Light traps with incandescent globes are used in a national monitoring program to detect the presence of Culicoides spp. responsible for the transmission of viruses to livestock and native animals. Recent events have suggested that the efficiency of these traps should be reconsidered and possibly improved. Subsequently, the response of eight species of Culicoides to light-emitting diodes (LEDs) was determined at two locations in New South Wales. Culicoides austropalpalis Lee & Reye, C. bunrooiensis Lee & Reye and C. marksi Lee & Reye were attracted to blue light. Responses to blue and green light could not be separated for C. bundyensis Lee & Reye, C. dycei Lee & Reye, C. nattiensis Lee & Reye and C. victoriae Macfie. Culicoides brevitarsis Kieffer was significantly attracted to green light. This species is the major vector of Akabane and bluetongue viruses in Australia. These responses were all significantly greater than the responses to the incandescent lights currently used in the light traps. The response to red light was less than the response to incandescent light for all species. Catches of C. brevitarsis were also related to the intensity of the green LEDs. These were more effective than the currently used incandescent globes at intensities between 46% and 142% of the incandescent intensity.
