Cytochrome P450 monooxygenases (CYPs) play essential physiological functions in insects. CYP303A1 is highly conserved in insect species studied to date, and shows an indispensable role for adult eclosion in both Locusta migratoria and Drosophila melanogaster . However, how CYP303A1 is regulated to control insect developmental processes remains uninvestigated. In this study, we discovered functional binding sites for miR‐184 in the coding sequence of LmCYP303A1 . The luciferase reporter assay showed that miR‐184 could target LmCYP303A1 and regulate its expression in vitro . Furthermore, overexpression of miR‐184 through microinjection of agomir to locusts reduced the transcripts of LmCYP303A1 and led to abnormal molting, which is similar to the phenotype of silencing LmCYP303A1 by direct injection of ds LmCYP303A1 to locusts. Meanwhile, down‐regulation of miR‐184 by injection of antagomir increased the LmCYP303A1 transcript and caused molting defects. These findings suggested that miR‐184 could target LmCYP303A1 to regulate the molting process in L. migratoria , which might be considered as a novel target for pest control.
