“…For the silkworm Bombyx mori, it has been reported that a highly female-biased olfactory receptor responds to (+)-linalool (Anderson et al 2009). Linalool is a common component of the scent of moth-pollinated flowers (Miyake et al 1998;Raguso & Pichersky 1999), and (þ)-linalool is the major floral component in the moth-pollinated Clarkia breweri (Raguso & Pichersky 1999). While foliage volatiles from host plants are sufficient to elicit oviposition in laboratory experiments (Mechaber et al 2002), it is possible that in nature floral (þ)-linalool acts in concert with foliage volatiles to attract M. sexta from a distance and/or at close range to elicit oviposition behaviour.…”

“…We hypothesized that individual FVs, from among the more than 60 compounds found in the scent of D. wrightii flowers (Raguso et al 2003), differentially modulate feeding and oviposition behaviours. We tested this idea focusing on linalool, a compound widespread in floral scents (Knudsen et al 2006) and a common constituent of the floral scent of hawkmoth-pollinated flowers (Miyake et al 1998;Raguso & Pichersky 1999). Although a minor component in the D. wrightii flower odour (Raguso et al 2003), linalool is an important FV, mediating nectar foraging in M. sexta (Riffell et al 2009a).…”

Antagonistic effects of floral scent in an insect–plant interaction

In southwestern USA, the jimsonweed Datura wrightii and the nocturnal moth Manduca sexta form a pollinator-plant and herbivore-plant association. Because the floral scent is probably important in mediating this interaction, we investigated the floral volatiles that might attract M. sexta for feeding and oviposition. We found that flower volatiles increase oviposition and include small amounts of both enantiomers of linalool, a common component of the scent of hawkmoth-pollinated flowers. Because (þ)-linalool is processed in a female-specific glomerulus in the primary olfactory centre of M. sexta, we hypothesized that the enantiomers of linalool differentially modulate feeding and oviposition. Using a synthetic mixture that mimics the D. wrightii floral scent, we found that the presence of linalool was not necessary to evoke feeding and that mixtures containing (þ)-and/or (2)-linalool were equally effective in mediating this behaviour. By contrast, females oviposited more on plants emitting (þ)-linalool (alone or in mixtures) over control plants, while plants emitting (2)-linalool (alone or in mixtures) were less preferred than control plants. Together with our previous investigations, these results show that linalool has differential effects in feeding and oviposition through two neural pathways: one that is sexually isomorphic and non-enantioselective, and another that is female-specific and enantioselective.

“…59 Furthermore, linalool was the most common compound emitted in the floral scents of moth-pollinated plants belonging to different families. 60,61 It also elicited strong antennal responses from the hawkmoths Sphinx perelegans and Hyles lineata and from the butterfly Heliconius melpomene L. 62,63 Thus, major compounds found in Licuala are also common compounds in the floral scents of plants of other groups. Once the pollinators of Licuala spp.…”

“…There has been much progress in identification of compounds emitted by flowers, in the elucidation of biosynthetic pathways and characterisation of enzymes, yet the underlying mechanisms controlling rhythmic emission have only just begun to be revealed (Kolosova et al 2001). Floral volatiles may attract pollinators (Knudsen et al 1993;Borgkarlson et al 1994;Schiestl et al 1997;Miyake et al 1998;Ervik et al 1999;Odell et al 1999;Jurgens et al 2000) or deter herbivores (Omura et al 2000). In some cases there has been apparent co-evolution of plant and pollinator(s), with closely matched patterns of insect activity and emission rhythms (Galen 1996;Ervik et al 1999).…”

The control of rhythmic emission of floral volatiles emitted from Rosa damascena semperflorens cv. 'Quatre Saisons' throughout floral development under various light regimes was studied. 2-Phenylethanol was the major volatile emitted in addition to monoterpenols, oxidised monoterpenols, monoterpenes and aromatic compounds. All detected volatiles were emitted rhythmically, with maximum peaks coinciding 8-10 h into a 12-h photoperiod. For some compounds a secondary, nocturnal peak was apparent. The primary and secondary maxima both occurred at approximately 24-h intervals. Rhythms appeared to be regulated endogenously: rhythmic emission continued upon exposure to continuous light or continuous darkness, and a phase shift in emission was induced upon inversion of the photoperiod. Additionally, emission continued after flower excision. A similar profile of free volatiles was stored within the floral tissue, together with glycosidic forms of 2-phenylethanol (>99% beta-D-glucoside), benzyl alcohol, citronellol and geraniol. Regression analysis indicated a significant decrease in glycosylated 2-phenylethanol through the photoperiod. These results suggest that glycosylated volatiles stored within petals may be a source of rhythmically emitted volatiles.
