Abstract
In order to understand the biological significance of flower odour for attraction of mosquitoes, electrophysiological responses to headspace flower odour samples of Silene otites (L.) Wibel were investigated on Culex pipiens pipiens biotype molestus Forskal 1775 and Aedes aegypti L. using coupled gas chromatographic electroantennographic detection (GC-EAD). No remarkable differences in antennal responses to the odour compounds have been found between these two mosquito species. Further, the behavioural attractiveness of the electrophysiologically active compounds, singly or as multiple odour mixtures, was evaluated with bioassay experiments with C. pipiens molestus. In bioassays, C. pipiens responded to 14 electrophysiologically active compounds in different magnitudes (65–20%) and acetophenone, linalool oxide (pyranoid), phenyl acetaldehyde and phenylethyl alcohol were found as more attractive incomparison to the least attractive compound, hexanol. In two-stimulus choice test, mosquitoes were significantly more attracted to the mixture of the four most attractive compounds compared to the mixture of all 14 compounds. The results of present study confirm that floral odours are attractive cues for mosquitoes.
