Abstract:In order to understand the chemistry relation between figs (Ficus spp., Moraceae) and their pollinators (Agaonidae, Chalcidoidae, Hymenoptera) and allocation mechanism, the volatiles from Ficus curtipes fruits at female phase and post-pollination stage were extracted by dynamic headspace technique and identified by GC and GC-MS analysis. The results showed that there were 45 volatile compounds isolated from F. curtipes fruits, and mainly consisted of monoterpenes and sesquiterpenes. The compounds, including 6-methyl-5-hepten-2-one, (E)-β-ocimene, trans-β-farnesene, α-farnesene, α-pinene, sabinene, cis-β-ocimene, cis-β-bergamotene, germacrene D and (E)-4,8-dimethyl-1,3,7-nonatriene may involve in the specificity of chemical signals. The volatile release amount at female phase was obviously higher than that at post-pollination stage. There were significant temporal and spatial variations among floral stages and different individuals. These implied that specific chemical interactions existed in nursery pollination mutualisms between figs and their pollinators, such as Eupristina sp., Diaziella yangi and Lipothymus sp.
