| 为了解小贯小绿叶蝉Empoasca onukii Matsuda对光的行为反应，为茶园害虫综合防治提供新思路，本研究利用光谱行为学，采用18种LED单色光源对小贯小绿叶蝉的趋光行为进行了研究。结果显示，小贯小绿叶蝉成虫对18个光源中的黄光（590~595 nm）趋向性相对较强，其次为紫光（420~425 nm），对白色光源（对照）的趋向性最低。趋光性由大到小分别为黄光（590~595 nm），紫光（420~425 nm），紫外光（390~395 nm），蓝光（460~465 nm）。忌避性较强的分别为橙光（600~605 nm），对照，冰蓝青光（490~495 nm），绿光（520~525 nm）。17种光谱与对照光结合显示，小贯小绿叶蝉对不同光谱的选择发生了变化，更倾向于先择紫外光（370~375 nm、380~385 nm、385~390 nm），紫光（420~425 nm），其次为琥珀色光（595~600 nm），趋光率最低的为蓝光（460~465 nm）和红光（660~665 nm）。双光谱结合时，其选择随不同的结合而发生改变。黑暗、对照和光谱间相结合处理时，白光结合下对光谱的选择趋向性显著高于黑暗条件，两者间呈负相关。小贯小绿叶蝉对黄光（590~595 nm）和紫外光（370~375 nm）的趋向性较强，而对橙光（600~605 nm）、绿光（520~525 nm）和蓝光（460~465 nm）有显著的忌避性。可利用其对光谱的选择性，在室内饲养或茶园防治中采用相应的光谱进行处理，从而达到合理利用的目的。 |

| To understand the behavior response of Empoasca onukii Matsuda to light and provide new ideas for integrated pest control in tea garden， In this study, 18 LED monochromatic light sources were used to study the phototactic behavior of the E. onukii. The results showed that, the adults of E. onukii had relatively strong tendency to yellow light at 590~595 nm in 18 light sources, followed by purple light at 420~425 nm, and had the lowest tendency to white light(control). Phototaxis from large to small were respectively, the phototaxis of yellow light was 590~595 nm, purple light was 420~425 nm, ultraviolet light was 390~395 nm, and blue light was 460~465 nm. Orange light(600~605 nm), natural white, glacial blue-green light(490~495 nm) and green light(520~525 nm) were the most avoidable. 17 spectra combined with natural white 〖HJ〗light were displayed that the selection of different spectra by E. onukii changed, and it was more inclined to choose ultraviolet light(370~375 nm, 380~385 nm, 385~390 nm), violet light(420~425 nm). The second was amber light(595~600 nm), the lowest phototaxis were blue light(460~465 nm) and red light(660~665 nm). The choice of bispectral combination changed with different combination. When the light was combined with darkness, CK and spectrum, the selectivity of white light was significantly higher than that of dark, and there was a negative correlation between them. E. onukii had strong tendency to yellow light(590~595 nm) and ultraviolet light(370~375 nm), but had significant aversion to orange light(600~605 nm), green light(520~525 nm) and blue light(460~465 nm). It could be used in indoor breeding or tea garden control by using its spectrum selectivity, so as to achieve the goal of reasonable utilization. |
