Functional Characterization of Three Odorant-Binding Proteins in Sex Pheromones and Host Plant Volatiles Detection in Bradysia odoriphaga

-silenced adults. Our findings suggest that BodoOBP2 and BodoOBP4 mediate both pheromone communication and host-plant detection, while BodoOBP8 mainly transports pheromones. These results advance our understanding of olfactory mechanisms in Diptera and provide molecular targets for olfactory-based management of this pest.
