“…However, in some cases, unusual compounds have been reported. In early work on the arrow arum, Peltandra virginica, an aquatic Araceae involved in a mutualism with its pollinator fly (Elachiptera formosa), Patt et al (1992Patt et al ( , 1995 octane and a molecular weight 142 analog, emitted by flowers in high concentrations. Although they did not test directly for effect of these two compounds on attraction of the mutualistic fly or other co-pollinators, these novel compounds could be good candidates for 'private channels'.…”

“…The results of these studies indicate that chemical mediation plays a key role in partner encounter, allowing pollinators to locate host plants and find floral rewards, i.e. breeding sites (Patt et al 1992;Gibernau et al 1998; Grison-Pigé et al 2002a;Jürgens et al 2003;Dötterl and Jürgens 2005;Svensson et al 2005;Okamoto et al 2007;S.

Floral scents: their roles in nursery pollination mutualisms

Mutualisms are interspecies interactions in which each participant gains net benefits from interacting with its partner. In nursery pollination mutualisms, pollinators reproduce within the inflorescence they pollinate. In these systems, each partner depends directly on the other for its reproduction. Therefore, the signal responsible for partner encounter is crucial in these horizontally transmitted mutualisms, in which the association between specific partners must be renewed at each generation. As in many other interspecies interactions, chemical signals are suspected to be important in the functioning of these mutualisms. We synthesized and compared the published data available on the role of floral scents in the functioning of the 16 known independently evolved nursery pollination mutualisms. So far, attraction of pollinators to their specific hosts has been investigated in only seven of these systems, and the majority of the studies have been conducted on one of them, fig/fig wasp interactions. While such unevenness of the information limits the potential for meta-analysis, some patterns emerge from this review concerning the role of flower volatiles in maintaining the specificity of pollinator attraction, in signaling the appropriate phenological stage for pollinator visit, in attracting the pollinator toward the rewardless sex in dioecious plant species and in aiding the location and exploitation of resources by parasites and predators associated with these mutualisms. Finally, we highlight new perspectives on the evolution of signals in these diversified systems depending on the age and the degree of specificity of the interaction, and on the effect of phylogenetic inertia on the evolutionary dynamics of plant signals.

Two aroid congeners, Alocasia odora and Alocasia cucullata , grow on Okinawa Island, Japan. Two floricolous species of Colocasiomyia alocasiae and Colocasiomyia xenalocasiae (Diptera: Drosophilidae), previously known to be specific pollinators for A. odora , were found pollinating A. cucullata . We collected the floral volatiles of A. odora and A. cucullata and compared them using gas chromatography and mass spectrometry because floral volatiles act as attractive signals for these pollinators. The volatile compositions detected were similar and dominated by methyl salicylate, 4,8-dimethyl-1,3,7-nonatriene, b b b b -caryophyllene, bicyclogermacrene, methyl benzoate and a a a a -humulene, which means it is likely that the flies cannot discriminate between the two plant species when they search for hosts. Interspecific hybridization did not occur when A. odora was hand pollinated with A. cucullata pollen, suggesting that the movement of flies from one host species to another will result in wastage of pollen. Adults of both Colocasiomyia flies emerged from A. cucullata inflorescences collected in the field, suggesting that their larvae can also develop on A. cucullata . We did not find any difference in larval performance of C. alocasiae on A. cucullata or A. odora . C. alocasiae does not appear to suffer any ill effects when using A. cucullata as a host plant. The partnership between A. cucullata and the two Colocasiomyia flies may be an example of exaptation, although other possibilities cannot be excluded.
