and homolog 1 Comediate the Action of Juvenile Hormone/ Signaling Pathway in Vitellogenesis of (J.E. Smith).

is a major migratory invasive pest and is of global concern. Vitellogenesis, a crucial process for population multiplication in oviparous insects, is regulated by endocrine hormones. In this study, three primary responders to JH signaling, the JH receptor gene , and the downstream transcription factor and , were first cloned and identified. RNA interference results showed that silencing significantly down-regulated the transcription levels of and , as well as the key reproductive genes () and (). Similarly, silencing and also inhibited the transcription of and . Silencing of , , and genes resulted in blocked ovarian development and a significant decrease in reproduction. These findings confirm that and comediate the action of the JH- signaling pathway in vitellogenesis of , providing new targets and insights for pest control.
