Abstract: The study on the pollination ecology of cultivated Ficus pumila var. awkeotsangshowed that this plant had two apparent blossoming periods, i.e., in spring and autumn, which were relatively longer than those of the wild one. Cultivated Ficus pumila var. awkeotsang couldn't rely on the wasps living in the variant syconia to pollinate or lay eggs. Under the circumstances the wasps were separated from wild F. pumila var. awkeotsang, the pollination system was damaged because of the absence of the wasps. The pollination wasps could be introduced artificially to cultivated F. pumila var. awkeotsang, but the pollination system was restored relatively slowly. The rate of syconia hanging on trees could only reach 51.11% after four years, with an average production rate of the female flowers being 64.37%, and an average gall tuming rate of gall flowers being 64.35%. The growing syconia degree of female and male flowering phases was low, and the collective way of the wasps’ flying out and the small number of the wasps entering the syconia were the causes of low rate co-existing breeding.
