Females of Forcipomyia monilicornis are specific pollinators of Aristolochia pistolochia, while males and females of two Dasyhelea species are specific pollinators of Aristolochia clematitis.
- Why it matters: Reproductive interference among sympatric plants may be reduced when floral traits attract different pollinator assemblages, but the trait-to-pollinator links are poorly known for many systems.
- What they did: Pollinators were surveyed on three co-flowering Mediterranean Aristolochia species, and floral volatile organic compounds were profiled; VOCs were then tested electrophysiologically using pollinators of A. rotunda and A. pistolochia.
- The result: Floral odours of A. rotunda and A. pistolochia differed significantly and elicited specific electrophysiological responses, supporting that selective attraction is likely mediated by specific VOCs.
