东方粘虫Mythimna separata是东亚的一种农业害虫。粘虫蛾对绿色（520 nm）光具有高趋光性反应。夜间生活在特定波长光下的昆虫的生物学特性会发生变化，因此保幼激素（JH）水平可能会受到这种光的影响。本研究评估了不同发育阶段（幼虫、蛹和成虫）的总JH水平的变化。Separata在绿色光下以不同的暴露时间在夜间（或黑暗期）饲养。结果表明，与不暴露于绿色光的组相比，当夜间绿色光的每日暴露时间延长时，末龄幼虫（22 d）和高龄蛹（8 d）的JH水平显著降低，而低龄蛹（4 d）和成虫（3、6和9 d）的JH水平显著升高。此外，雄蛾和雌蛾的JH水平存在显著差异。我们认为M.绿色光在夜间（或黑暗期）对粘虫有调节作用。本研究结果将有助于解释光环境与夜蛾生物学特性的关系。
The oriental armyworm Mythimna separata is an agricultural insect pest in Eastern Asia. Mythimna separata moths have a high phototactic response to green (520 nm) light. The biological characteristics of insects living under light of a specific wavelength at night can change and, accordingly, Juvenile hormone (JH) levels may be influenced by this light. The present study evaluates changes in the total JH levels at different developmental stages (larvae, pupae and adults) of M. separata reared under green light with different exposure periods at night (or dark period). The results show that, when the exposure time per day of the green light at night is extended, the JH levels in the final‐instar larvae (22 days) and older age pupae (8 days) are significantly reduced, and the JH levels in earlier age pupae (4 days) and adults (3, 6 and 9 days) are significantly increased, compared with groups not exposed to green light. Additionally, the JH level of male moths significantly differs from that of the female moths. We suggest that the JH level of M. separata insects could be regulated by the green light at night (or dark period). The findings of the present study will help to explain the relationship between the light environment and biological characteristics in nocturnal moths.
