| 【目的】探索LED光不同光波长对荔枝蒂蛀虫卵巢发育等繁殖生物学的影响，初步明确抑制该虫产卵交配等行为的最佳光波长，为光驱避法防控荔枝蒂蛀虫技术的大面积推广提供理论依据。【方法】模拟田间光照条件，每日06:00-19:00光照强度统一设定为500Lux，19:00-次日06:00 光照强度统一（其中混合光的光照强度为100Lux，单基色光的光照强度为50Lux），研究LED混合光450nm、540nm、610nm光波长和单基色光400nm、420nm、440nm、460nm、480nm、500nm、520nm、600nm光波长夜晚光照荔枝蒂蛀虫成虫1、3、5、7日后，逐日记录各处理的荔枝蒂蛀虫雌虫产卵量，统计其交配率、平均每雌产卵量及卵巢发育级别等。【结果】夜晚光照1d后，不同光波长的混合光和单基色光对荔枝蒂蛀虫的卵巢发育级别和产卵量均无显著影响，但其交配率显著低于对照；夜晚光照3d-7d后，混合光和单基色光对荔枝蒂蛀虫产卵、交配和卵巢发育均有显著的抑制作用，其中单基色光400nm-500nm光波长的抑制作用最强，520nm光波长的抑制作用稍弱，600nm光波长的抑制作用最弱，但仍显著强于对照。460nm-480nm光波长对荔枝蒂蛀虫卵巢发育的抑制作用最强。光照后荔枝蒂蛀虫的雌蛾卵巢有发育异常情况，其中单基色光460nm-480nm光波长光照3d-7d后荔枝蒂蛀虫雌蛾发育异常的卵巢比率较高。【结论】夜晚光照3d-7d后，混合光和单基色光对荔枝蒂蛀虫产卵、交配和卵巢发育等均有显著抑制作用且影响趋势基本一致，推测460nm-480nm光波长是抑制荔枝蒂蛀虫产卵交配等繁殖生物学的最佳光波长，但仍需田间试验验证。 |

| 【Objective】To explore the effects of different wavelengths of LED light on the reproductive biology of Conopomorpha sinensis (Lychee Stem Borer), such as ovarian development, and to initially identify the optimal light wavelength that inhibits the insect's behaviors like oviposition and mating. This study aims to provide a theoretical basis for the large-scale promotion of light avoidance technology in the prevention and control of C. sinensis.【Methods】By simulating field light conditions, the light intensity was uniformly set to 500 Lux during the daytime (06:00-19:00 daily), and the light intensity was kept consistent during the night (19:00-06:00 the next day) — among which, the light intensity of mixed light was 100 Lux, and the light noise intensity of single primary color light was 50 Lux. The study investigated the effects of night illumination treatments on adult C. sinensis using LED mixed light with wavelengths of 450 nm, 540 nm, and 610 nm, as well as single primary color light with wavelengths of 400 nm, 420 nm, 440 nm, 460 nm, 480 nm, 500 nm, 520 nm, and 600 nm. After 1, 3, 5, and 7 days of treatment, the egg production of female moths in each group was recorded daily, and their mating rate, average fecundity per female, and ovarian development grade were statistically analyzed.【Results】After 1 day of nighttime illumination, neither the mixed light nor monochromatic light of different wavelengths had a significant effect on the ovarian development grade or egg production of C. sinensis, but their mating rate was significantly lower than that of the control group. From 3 to 7 days of nighttime illumination, both mixed light and monochromatic light exhibited a significant inhibitory effect on the egg laying, mating, and ovarian development of C. sinensis. Among them, monochromatic light with wavelengths of 400 nm–500 nm showed the strongest inhibitory effect, followed by 520 nm, and 600 nm had the weakest inhibitory effect, which was still significantly stronger than that of the control group. Monochromatic light with wavelengths of 460 nm–480 nm had the strongest inhibitory effect on the ovarian development of C. sinensis. Abnormal ovarian development was observed in female moths after illumination, and the ratio of abnormal ovarian development was relatively high in female moths exposed to monochromatic light of 460 nm–480 nm for 3–7 days.【Conclusion】From 3 to 7 days of nighttime illumination, both mixed light and monochromatic light exerted a significant inhibitory effect on the reproduction-related biological traits of C. sinensis, including egg laying, mating, and ovarian development, with a basically consistent impact trend. It is speculated that the wavelength range of 460 nm–480 nm is the optimal for inhibiting the reproductive biology (such as egg laying and mating) of C. sinensis, but further field experiments are still needed for verification. |
