Olfactory variation among closely related cactophilic Drosophila species.

ABSTRACT: Chemosensation plays an important role in a wide range of behaviors including host identification and localization, oviposition site selection, and mate recognition. Variation in the ability to detect chemical signals may influence behavior in animals like insects that use volatile cues emitted from plants when discriminating between potential hosts. Differences in odor detection has been demonstrated to play a crucial role in driving changes in host use within and between insect species, leading to reproductive isolation between populations and eventual speciation through specialized host adaptation. We examined between-species variation in odor tuning and asked whether it is linked to shifts in host plant use in the Drosophila repleta species group, a taxonomic radiation of flies special
