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.

Methods for identifying odorant receptors reactive to mosquito repellent compounds and methods for screening repellent compounds as well as repellent compositions include newly identified repellent compounds and their applications for protecting a subject against malaria or repelling mosquitoes in an area.

The computer-implemented method (100) for providing at least one fragrance molecule representation, representing a materializable fragrance molecule for fragrance or flavor product production, comprises: - a step (105) of determining at least one value representative of an odorant receptor activity target caused by the material exposition of said odorant receptor to the fragrance molecule associated with a fragrance molecule representation, - a step (110) of generating at least one fragrance molecule representation by a trained machine-learning model using as input value representative of an odorant receptor activity target, and - a step (115) of providing at least one of the generated at least one fragrance molecule representation.

The present invention belongs to the field of biotechnology and specifically discloses the use of the odorant receptor BdorOR94b1 as a target for controlling the fruit fly. Utilizing functional genomics, electrophysiology, behavioral science, and traditional chemical ecology methods, the present invention comprehensively analyzes the role of methyl eugenol in the mating behavior of the fruit fly and the key olfactory receptor used by males to recognize methyl eugenol. The key odorant receptor BdorOR94b1 used by the fruit fly to recognize methyl eugenol was identified for the first time, and its genomic coding region sequence and transcribed amino acid sequence information were obtained. This not only provides an important foundation for the subsequent screening of more stable and efficient structural analogs targeting this gene, but also provides a foundation for the development of nucleic acid pesticides.
