中文摘要：【目的】 柑橘木虱Diaphorina citri Kuwayama作为柑橘黄龙病的虫媒，对控制柑橘黄龙病的传播扩散和抑制其对柑橘生产造成的经济损失具有重要作用。目前，物理防控是柑橘木虱绿色防控与监测预报的重要技术，其中基于LED光源的灯诱技术具有显著的开发潜力。本研究旨在明确不同时间（昼间与夜间）和不同场景（室内与室外）下，LED光源对柑橘木虱引诱效果及最优波长范围。【方法】 通过遮光箱与室外网笼分别模拟室内和室外两种场景，在昼间（9:00-10:00）和夜间（20:00-21:00）分别检测了白色、粉色、紫色（435-445 nm）、蓝色（455-460 nm）、绿色（525-530 nm）、黄色（590-595 nm）和红色（625-630 nm）7种不同波段颜色LED光源的诱虫效果。【结果】 在室内环境下，昼、夜间引诱柑橘木虱占比更高的皆为绿色和蓝色LED光源，两者无显著差异（P > 0.05）；在室外环境下，昼间引诱柑橘木虱占比更高的为蓝色、绿色和白色LED光源，三者无显著差异（P > 0.05），而夜间引诱柑橘木虱占比更高的为紫色、蓝色、绿色和白色LED光源，四者无显著差异（P > 0.05）。【结论】 在不同时间与场景下，蓝色和绿色LED灯具有更高引诱柑橘木虱效率，推荐作为柑橘木虱LED灯诱技术的候选可见光范围。研究结果为柑橘木虱灯诱技术的田间应用及其监测预警技术的开发提供了技术基础。
英文摘要：[Aim] Diaphorina citri plays an important
role as an insect vector for Citrus
Huanglongbing (HLB), contributing to the spread of HLB, leading to economic
losses in citrus production. Physical management is currently the main strategy
for monitoring, forecasting, and controlling citrus psyllid. Among these
strategies, LED light-based trapping technology has shown significant potential
for practical application. To determine the attractive effect of LED light
sources on citrus psyllids under different time periods and environmental
conditions, and to identify the optimal wavelength range. [Methods] We determined the attractive effects of seven
LED light sources. These included white, pink, purple (435-445 nm), blue
(455-460 nm), green (525-530 nm), yellow (590-595 nm), and red (625-630 nm),
under indoor and outdoor conditions during daytime（9:00-10:00） and nighttime (20:00-21:00). [Results] The results
demonstrated that green and blue LED light sources significantly increased the
attraction rate of D. citri. In the outdoor environment, blue, green,
and white LED light sources attracted the highest proportion of D. citri during the daytime. Conversely at night, purple, blue, green, and white LED
light sources attracted the most D. citri. [Conclusion] These findings indicate blue and green LED
lamps have superior attractant efficiencies under varying conditions of time
(day/night) and environment (indoor/outdoor). Thus, these lamps are recommended
as candidates within the visible light range of LED for the “lure and kill”
technology in citrus phyllid control. The findings of this study will
contribute to the development of a valuable light-attraction based technique
for the control, monitoring, and early detection of citrus psyllid.
