A plant virus enhances odorant-binding protein 5 (OBP5) in the vector whitefly for more actively olfactory orientation to the host plant.

This study described a novel mechanism that the olfactory system of vector insects could be regulated by a semipersistent plant virus, thereby affecting the insect olfactory behavior and their relationship with host plants. These results provided a basis for developing potential olfaction-based pest management strategies in the future.
