Despite its morphological similarity to the other species in the  Drosophila melanogaster  species complex,  D. sechellia  has evolved distinct physiological and behavioral adaptations to its host plant  Morinda citrifolia,  commonly known as Tahitian Noni. The odor of the ripe fruit of  M. citrifolia  originates from hexanoic and octanoic acid.  D. sechellia  is attracted to these two fatty acids, whereas the other species in the complex are repelled. Here, using interspecies hybrids between  D. melanogaster  deficiency mutants and  D. sechellia,  we showed that the  Odorant-binding protein 57e (Obp57e)  gene is involved in the behavioral difference between the species.  D. melanogaster  knock-out flies for  Obp57e  and  Obp57d  showed altered behavioral responses to hexanoic acid and octanoic acid. Furthermore, the introduction of  Obp57d  and  Obp57e  from  D. simulans  and  D. sechellia  shifted the oviposition site preference of  D. melanogaster Obp57d/e KO   flies to that of the original species, confirming the contribution of these genes to  D. sechellia 's specialization to  M. citrifolia . Our finding of the genes involved in host-plant determination may lead to further understanding of mechanisms underlying taste perception, evolution of plant–herbivore interactions, and speciation.
