摘要: 为探究不同波长LED光源对稻螟赤眼蜂生长发育及繁殖的影响,本研究在实验室条件下,采用6种不同波长LED光源,400 nm(紫光)、450 nm(蓝光)、530 nm(绿光)、580 nm(黄光)、630 nm(红光)和6000 k(白光),在稻螟赤眼蜂生长发育及繁殖过程中进行光照处理,观察统计其母代的单雌寄生数、子代的单雌寄生数、寿命、发育历期及雌蜂占比。试验结果表明,不同波长LED光照处理下稻螟赤眼蜂的寄生数、寿命、发育历期及雌蜂占比等指标均有显著性差异。在黄光处理下,母代及子代的寄生数量均受到了明显的抑制,但是黄光在延长稻螟赤眼蜂寿命上起到了较为显著的效果。红光处理下稻螟赤眼蜂子代的发育历期为235 h,红光明显延长了稻螟赤眼蜂子代的发育历期,对稻螟赤眼蜂的高效繁育起到了抑制作用。蓝光则可以增加种群中的雄蜂数量,使种群雌雄性比向雄性一方偏移,不利于稻螟赤眼蜂种群的繁育及应用。综上所述,不同波长的LED光源对稻螟赤眼蜂的生长发育及繁殖起到一定的调控作用,在繁育的过程中,应该避免使用黄光、蓝光等有抑制效果的光源,对稻螟赤眼蜂的实际应用提供一定的技术指导,并为进一步深入研究稻螟赤眼蜂对环境的适应性及提升其在生物防治中大规模饲养的扩繁效率提供了重要的理论依据。

Abstract: The study aims at clarifying the effects of LED light of different wavelengths on the development and reproduction of Trichogramma japonicum. The number of eggs laid per female in the parental and offspring generation, longevity, developmental duration and sex ratio of offspring of T. japonicum under six different LED lights (purple, 400 nm; blue, 450 nm; green, 530 nm; yellow, 580 nm; red, 630 nm; white, 6000 k) were observed and recorded. The results showed that there were significant differences in all the life-table parameters. The yellow LED light significantly restrained parasitic behaviors, but prolonged the longevity of parasitoids. The developmental duration was about 235 hours under red light. The red light obviously prolonged the duration of development and inhibited mass rearing efficiency. Besides, the number of male offspring increased under blue light, and is adverse for mass rearing and field application. In conclusion, the LED light at different wavelengths may exert negative effects on the development and reproduction of T. japonicum. In mass rearing, the light of inhibitory effects, such as yellow light or blue light, should be avoided. These results provide an important theoretical basis for further study of the environmental adaptability of T. japonicum and improvement of its mass rearing efficiency in a biological control program.
