The invention discloses an odor receptor gene SinfOR21 of sesamia inferens and application of the odor receptor gene SinfOR21. Belongs to the technical field of biology. According to the invention, sex pheromones of Zhejiang and Guangdong sesamia inferens strains and expression and functional verification of olfaction receptor genes of the sesamia inferens are identified and compared. The method comprises the following steps: firstly, identifying pheromone mixtures with region specificity, and verifying the behavior effectiveness of the pheromone mixtures in field trials; through transcriptome and function analysis, it is proved that a SinfOR21 receptor of the Zhejiang strain is specifically combined with Z11-16: OH, and a homologous receptor of the Guangdong strain does not have the function. And determining that the sex pheromone mixture of the sesamia inferens should be composed of Z11-16: Ac, 16: Ac and Z11-16: Ald. Different from reported sex pheromone mixtures of sesamia zhejiangensis, the sex pheromone mixture of sesamia zhejiangensis is composed of Z11-16: Ac, Z11-16: OH and Z11-16: Ald.
