Abstract: Experiments in attraction of face fly Musca autumnalis De Geer females to ornamental plants Euonymus europaeus and E. kiautschovicus were conducted in the laboratory with Y-shaped glass olfactometer. The two plant species could attract face fly female adults, but E. europaeus was better in attraction of face flies than E. kiautschovicus. Female face flies responded more actively to odors of flowers of Euonymus plants than to odors of leaves, but leaves also played some roles in attraction when applied alone, and synergized the attraction of flowers when used together. Flowers of E. europaeus were extracted with several solvents, and the results showed that water or methanol extracts were better in attraction than hexane extracts. Frozen flowers showed similar attraction effects to fresh ones.

Key words: Musca autumnalis De Geer, Euonymus europaeus, E. kiautschovicus, attraction, bioassays, volatiles, flower extracts
