In this study the phototactic response of anopheline mosquitoes to different luminous intensity light-emitting diodes (LEDs) was investigated. Centers for Disease Control-type light traps were changed by replacement of the incandescent lamps by 5 mm round type green (520 nm) and blue (470 nm) LEDs of different luminous intensities: green-LED traps with luminous intensities of 10,000, 15,000 and 20,000 millicandela (mcd) and the blue-LED traps with luminous intensities of 4000, 12,000 and 15,000 mcd. Our data showed that increasing luminous intensity has an effect on the attraction of anopheline mosquitoes to light traps, highlighting the importance of taking LEDs and light sources of high luminous intensity into account when using light-trap collections in monitoring populations of Anopheles species.
在本研究中，调查了按蚊对不同发光强度发光二极管（LED）的趋光反应。通过将疾病控制中心型诱蚊灯中的白炽灯替换为不同发光强度的5毫米圆形绿色（520纳米）和蓝色（470纳米）LED，对诱蚊灯进行了改装：发光强度为10000、15000和20000毫坎德拉（mcd）的绿色LED诱蚊灯，以及发光强度为4000、12000和15000 mcd的蓝色LED诱蚊灯。我们的数据表明，发光强度的增加对按蚊对诱蚊灯的吸引力有影响，这突出了在使用诱蚊灯收集法监测按蚊种群时，考虑LED和高发光强度光源的重要性。
