“…different shape of traps and flowers, may also have reduced the trap catches. Phenylacetaldehyde, the most attractive scent in our study, has been reported earlier as an attractant for diurnal and nocturnal Lepidoptera (Creighton et al 1973;Cantello and Jakobson 1979;Haynes et al 1991;Heath et al 1992;Honda et al 1998;Andersson and Dobson 2003) and honeybees (Blight et al 1997). Andersson et al (2002) describes phenylacetaldehyde as a characteristic compound of butterflypollinated flowers because of its widespread occurrence in such plants, but the compound has also been found in many other plants (Knudsen et al 1993).…”

We investigated scent composition and pollinator attraction in two closely related orchids, Gymnadenia conopsea (L.) R.Br. s.l. and Gymnadenia odoratissima (L.) Rich. in four populations during the day and night. We collected pollinators of both species using hand nets and sampled floral odour by headspace sorption. We analysed the samples by gas chromatography with mass spectrometry to identify compounds and with electroantennographic detection to identify compounds with physiological activity in pollinators. In order to evaluate the attractiveness of the physiologically active compounds, we carried out trapping experiments in the field with single active odour substances and mixtures thereof. By collecting insects from flowers, we caught eight pollinators of G. conopsea, which were members of four Lepidoptera families, and 37 pollinators of G. odoratissima, from five Lepidopteran families. There was no overlap in pollinator species caught from the two orchids using nets. In the scent analyses, we identified 45 volatiles in G. conopsea of which three (benzyl acetate, eugenol, benzyl benzoate) were physiologically active. In G. odoratissima, 44 volatiles were identified, of which seven were physiologically active (benzaldehyde, phenylacetaldehyde, benzyl acetate, 1-phenyl-2,3-butandione, phenylethyl acetate, eugenol, and one unknown compound). In field bioassays using a mixture of the active G. odoratissima compounds and phenylacetaldehyde alone we caught a total of 25 moths, some of which carried Gymnadenia pollinia. A blend of the active G. conopsea volatiles placed in the G. odoratissima population did not attract any pollinators. The two orchids emitted different odour bouquets during the day and night, but G. odoratissima showed greater temporal differences in odour composition, with phenylacetaldehyde showing a significant increase during the night. The species differed considerably in floral odour emission and this differentiation was stronger in the active than non-active compounds. This differentiation of the two species, especially in the emission of active compounds, appears to have evolved under selection for attraction of different suites of Lepidopteran pollinators.

In electroantennographic tests isosafrol, methyl salicylate, (ð)-lavandulol, geraniol, (E)-anethol, and -ionone evoked the largest responses from antennae of female or male Oxythyrea funesta (Coleoptera: Scarabaeidae, Cetoniinae) adult beetles. In field trapping tests in Hungary the 1 : 1 blend of (ð)-lavandulol and 2-phenylethanol attracted significantly more adult O. funesta than the single compounds. The addition of (E)-anethol, a previously described attractant for the species, was without effect. There was no difference in the responses of male or female beetles. The binary 2-phenylethanol/(ð)-lavandulol bait described in this study is recommended for the use in traps of O. funesta for agricultural purposes.

“…Today, many aromatics are used as Lepidoptera attractants. For example, a mixture of benzaldehyde, phenylacetaldehyde, 2-phenylethanol and benzyl alcohol, which was released from Abelia grandiflora [22] flowers, was a strong attractant for Trichoplusia ni moths. Heath et al [23] also reported that electrophysiological responses of Trichoplusia ni to phenylacetaldehyde were equal to responses from a mixture of benzaldehyde, benzyl acetate and phenylacetaldehyde.…”

Electroantennogram responses of fall webworms (Hyphantria cunea) to 55 host volatile compounds were conducted. Results showed that male moths were more responsive to trans-2-hexenyl acetate, nonanal, hexanal, trans-2-hexenal, hexanol, isoamyl acetate, acetic acid cis-3-hexenyl ester, ethyl acetoacetate, citronellal and (+)-citronellal, and females were more responsive to hexanol, hexanal, acetophenone, isoamyl acetate, nonanal, trans-2-hexenal, acetic acid cis-3-hexenyl ester, citronellal, cis-3-hexen-1-ol and trans-2-hexen-1-ol. Seven bioactive compounds were also selected for further dosage response experiments, and a positive correlation was found between the fall webworm and the tested compounds. A maximum dosage level of 1000 g was tested and found to elicit significantly higher activity from male moths compared with lower (1, 10, 100 g) concentrations.
