Abstract in another language
Syrphid flies are frequent flower visitors, but little is known about the cues they use to find flowers. We determined the importance of visual and olfactory cues in a flight cage bioassay using Cirsium arvense (Asteraceae)flower heads and experienced Episyrphus balteatus (Diptera,Syrphidae). We tested the response of antennae of the fliesto headspace in florescence scent samples by using gaschromatography coupled to electroantennography (GCEAD).The bioassays revealed that both sexes of experienced flies rely on olfactory, not visual, cues to find C. arvenseflower heads. The GC-EAD measurements demonstrated that male and female flies have olfactory receptors for several of the compounds emitted by the inflorescences.These electroantennographic-active compounds may be responsible for the attraction of flies to the C. arvense flower heads. Among the compounds eliciting an antennal response are methyl salicylate and 2-phenylethanol, which were previously described as syrphid attractants. Overall, our study demonstrates for the first time that a syrphid fly uses olfactory and not visual cues to find a pollen/nectarhost-plant.
