  Abstract 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.
