Ficus awkeotsang Makino and Ficus pumila L. are both Ficus (Moraceae) species. As an endemic plant and a special fruit tree species of China, F. awkeotsang is cultivated in the south region of Yangtze River in China, whereas F. pumila is widely used in vertical greening in the garden. F. awkeotsang and F. pumila are dioecious, both of which have a stable mutualistic relationship with Wiebesia pumilae (Hymenoptera: Chalcidoidea: Agaonidae). The maintenance of the fig-fig wasp mutualism system is strongly dependent on the chemical orientation of pollinating fig wasps using fig volatiles. The pollinating fig wasps trace the fig volatiles of their particular host and enter the figs at receptive phase (female flower phase) only, where they oviposit for themselves and meanwhile causing the plants pollinated. Infochemicals play a decisive role in maintaining the fig/pollinator mutualisms. Eight infochemicals including linalool, benzyl ethylene, benzyl alcohol, geraniol, terpineol, farnesol, vanillin and methyl benzoate were chosen for tests based on the volatile components in the recepetive phase syconia of F. awkeotsang, F. pumila and other figs．Two groups of Wiebesia pumilae from F. awkeotsang and F. pumila were tested． In this paper, the tropistic responses of two groups of Wiebesia pumilae from different sources to eight individual infochemicals and a mixture of linalool, benzyl alcohol and terpineol were measured using a Y-tube olfactometer in the laboratory. The responses of the two groups to the same infochemicals were compared. The differences in effects on the selection behavior of Wiebesia pumilae to individual and mixed infochemicals were studied. The results showed that 3% and 5% linalool, 5% benzyl ethylene, 7% benzyl alcohol, 5% and 7% terpineol, and 7% farnesol exhibited significant attractive effect, whereas 7% methyl benzoate exhibited significant repellent effect, and vanillin exhibited little effect on both of the groups of Wiebesia pumilae, indicating that the types and concentrations of infochemicals had significant effects on the selection behavior of fig wasps, suggesting that the chemical compositions and concentrations of fig volatiles had effects on the selection behavior of their pollinator fig wasps. The results of orthogonal experiment showed that the synergistic and antagonistic effects on fig wasps were exhibited when the individual infochemicals were mixed. The mixture of 5% linalool, 3% benzyl alcohol and 3% terpineol (i.e. optimum combination) exhibited extremely significant attraction to both of the groups of Wiebesia pumilae, and the interaction between different infochemicals was very significant. This further indicated that only certain compounds in a particular concentration could produce strong attractive effect on fig wasps. The similarities and differences between the responses of the two groups of Wiebesia pumilae to infochemicals suggest that the two groups of Wiebesia pumilae have a close genetic relationship between them, but may be different in the signal transduction of chemical communication between them and their hosts. The infochemicals (e.g. linalool) widely exist and account for a large proportion of the volatile components in recepetive phase syconia, which might be related to the long-range host-location of wasps. However, the short-range special host-location of wasps might be dependent on the chemical spectrum consisting of various infochemicals according to certain concentrations and proportions strictly. The results of this experiment will facilitate the theoretical study on the chemical ecology of the fig-wasp symbiosis and the high-yield cultivation of F. awkeotsang.
