中文摘要：【目的】 研究肚倍蚜Kaburagia rhusicola Takagi对不同光源的趋光行为及应用不同光源诱集效果，为研发肚倍蚜收集装置提供科学依据。【方法】 通过室内行为学试验分析21种不同波长灯光对肚倍夏迁蚜的引诱效果，并测试生产应用上4种不同光源对肚倍夏迁蚜诱集效果。【结果】 肚倍夏迁蚜对325-770 nm范围内的光（光强15 lx）具有趋性。肚倍夏迁蚜对670 nm单色光趋向性最强，极显著高于其他波段的单色光（除了460 nm以外）。其次是460、610和590 nm的单色光，显著高于除了670 nm以外其他波段的单色光。利用可移动式收集装置结合灯光收集肚倍夏迁蚜所需要的时间为3 d。而且，4种光波的灯诱集规律存在较大的差异。橙色LED灯（600-610 nm）、红色LED灯（655-665 nm）和白色日光灯诱集规律相似，收集曲线都是“凸”形的。蓝色LED灯（450-460 nm）诱集规律与前3种灯相反，收集曲线是“凹”形的。【结论】 肚倍夏迁蚜的最敏感光谱是670、460、610 和590 nm的单色光。LED灯可结合移动式收集装置用于肚倍夏迁蚜的迁飞收集，有助于提高收集效率。
英文摘要：[Objectives] To investigate the phototaxis of Kaburagia rhusicola Takagi adults to different light wavelengths, and the effects of phototaxis on collection efficiency, in order to develop a special collection device for these aphids. [Methods] The phototaxis of K. rhusicola to 21 monochromatic lights from 325-770 nm was measured in a laboratory and differences in the number of aphids trapped by 4 different types of light were analyzed. [Results] Every monochromatic light (325-770 nm, 15 lx) induced phototactic responses. Summer migrants significantly preferred red light (670 nm) to all other wavelengths except 460 nm (P< 0.01). In addition to 670 nm, three other light wavelengths; 460, 610, and 590 nm, were also significantly preferred to the other wavelengths (P < 0.05). The relative attractiveness of four different light wavelengths in mobile collection devices specially designed for collecting the summer migrants was tested over three days. There were large differences in the capture-time curves of the 4 wavelengths. The curves of the orange LED light (600- 610 nm), the red LED light (655-665 nm) and the white fluorescent light were all “convex” shapes. However, that of the blue LED light (450-460 nm) was “concave”. [Conclusion] Summer migrants are most attracted to 670, 460, 610 and 590 nm monochromatic lights. The combination of a movable collecting device and an LED light source can improve the collection efficiency of summer migrants.
