The evolutionary tree of each zinc finger in functional area of Nlkr-hl was analyzed via MEGAS. 0 software, and expression status of FAMeT and JHE after interference of N/kr-hl was determined using qPCR technology. The results showed that the functional area of N/kr-hl mainly included eight zinc fingers, and the conservativeness of Znl and Zn8 was relatively lower. In the brown planthopper with N/b＇-hl gene knockout, the expression levels of FAMeT and JHE increased. The paper provided the theoretical basis for understanding molecular mechanism of juvenile hormone signaling pathway and biological control of brown planthopper.展开更多
