Title Influence of green light illumination at night on biological characteristics of the oriental armyworm, Mythimna separata (Lepidoptera: Noctuidae) Type Journal Article

Abstract 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.

Title Influence of green light at night on Juvenile hormone in the oriental armyworm Mythimna separata (Lepidoptera: Noctuidae) Type Journal Article
Year 2019 Publication Physiological Entomology Abbreviated Journal Physiol. Entomol.
Volume 44 Issue 3-4 Pages 245-251
Keywords Animals; armyworm; Mythimna separata; Insects; Asia; green light
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.
