| 中文摘要: |
| 柑橘木虱Diaphorina citriKuwayama是柑橘黄龙病（huanglongbing，HLB）的重要传播媒介。为了利用灯光诱控技术防治柑橘木虱，本实验于室内条件下研究柑橘木虱对波长为360 nm、400 nm、440 nm、 480 nm、 520 nm、560 nm和600 nm的LED光源和不同光照强度趋光行为反应。结果表明：柑橘木虱对7种单色光都有正趋向性。其中雌雄混合存在时对400 nm的紫光趋向性最强，其次是560 nm的绿光；单独处理时，雌成虫对400 nm的紫光趋性最强，其次是520 nm的绿光，雄成虫则是对520 nm的绿光趋性最强，其次是400 nm的紫光。在200 μw/cm^2到1 000 μw/cm^2的光照强度范围内，随着光照强度的增大，柑橘木虱雄成虫趋光行为逐渐增强，在光照强度为1 000 μw/cm^2时趋光行为最强，但雌成虫趋光行为变化不明显。该研究表明：柑橘木虱雌雄成虫具有明显的正趋光性，且对光谱和光强的反应存在差异。这一结果可为柑橘木虱田间的灯光诱控提供实验依据。 |

| The Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Liviidae), is a vector of huanglongbing (HLB）. In order to use light trap technology to control D. citri, we investigated the phototaxis behavior of D. citrito LED lights at different wavelengths of 360 nm, 400 nm, 440 nm, 480 nm, 520 nm, 560 nm and 600 nm and different intensity under indoor conditions. The results showed that the Asian citrus psyllid had positive phototaxis to 7 monochromatic lights. When the female and male adults were mixed and exposed to the LED lights, the citrus psyllids were most attracted by violet LED light at the wavelength of 400 nm, following by green LED light (520 nm）. And when the adults were treated by different gender, female adults were most attracted by violet LED light (400 nm), following by the green light (520 nm), male adults were most attracted by green LED light (520 nm), following by the violet light (400 nm）. The phototactic ratios of male adults were gradually enhanced with the light intensity to exposure increasing from 200 μw/cm2 to 1 000 μw/cm2, instead of female adults without significant variation. This study indicated that Asian citrus psyllids of male and female adults had significantly positive phototaxis and different responses to spectrum and light intensity. These results will provide experimental evidences for trapping citrus psyllid by light in the fields. |
