The oriental armyworm, Mythimna separata is an important crop pest in eastern Asia. Nocturnal insects, including nocturnal moths, have phototactic behavior to an artificial light source. Phototactic behavior in insects is species-specific in response to different wavelengths of light sources. Our previous study showed that green (520 nm) light emitting diode (LED) light resulted in a significantly higher phototactic behavior in M. separata moths compared to the other wavelength LED lights. The goal of the present study is to investigate the influence of green light illumination on biological characteristics of different developmental stages in M. separata. Our results revealed that when different developmental stages of M. separata were exposed to the green light illumination in a dark period, several biological characteristics in all developmental stages except for egg stage were positively changed, but those of F1 generation M. separata which are next generation of the adults exposed to the green light did not significantly change compared with the control level. These findings suggest that green light illumination at night (or dark period) has a positive effect on the development and longevity of M. separata.

夜间绿光照明对粘虫Mythimna separata（鳞翅目：夜蛾科）生物学特性的影响

东方粘虫，蜉蝣是东亚地区重要的农作物害虫。夜行性昆虫，包括夜行性飞蛾，对人造光源具有趋光行为。昆虫的趋光行为是物种特异性的，以响应不同波长的光源。我们之前的研究表明，绿色（520 nm）发光二极管（LED）光导致显着更高的趋光行为米.分离飞蛾与其他波长的 LED 灯相比。本研究的目的是研究绿光照明对不同发育阶段生物特征的影响。M. separata. 我们的研究结果表明，当不同的发育阶段M. separata在黑暗时期暴露在绿光照射下，除卵期外，所有发育阶段的几个生物学特征都发生了积极变化，但 F1一代M. separata与对照组相比，暴露在绿光下的下一代成年人没有显着变化。这些研究结果表明，夜间（或黑暗时期）的绿光照明对动物的发育和寿命有积极影响。M. separata.
