- <abstract abstract-type="main" id="eea12338-abs-0001"> <title>Abstract</title> <p>Figs (Moraceae) and pollinator fig wasps (Hymenoptera: Agaonidae) have a highly specific mutualistic relationship but fig wasps occasionally enter atypical hosts, and this can lead to hybrid fig trees and the potential for gene flow between species. Many fig trees are dioecious, with fig wasp offspring developing in galled ovules inside figs on male trees, whereas seeds develop only in figs on female trees. We generated experimental hybrids between the Asian <italic>Ficus montana</italic> Blume and a closely related African species <italic>Ficus asperifolia</italic> Miquel. Male F1s were sterile if entered by <italic>Kradibia tentacularis</italic> (Grandi) (Agaonidae), the pollinator of <italic>F. montana</italic>, because its offspring always failed to develop, without ovule enlargement. As with the F1s, figs on most male backcross plants [<italic>F. montana</italic> × (<italic>F. montana </italic>×<italic> F. asperifolia</italic>)] also aborted shortly after pollinator entry, resulting in a higher turnover of figs than with <italic>F. montana</italic>, although the times taken for the figs to reach receptivity were similar. Pollinator larvae nonetheless consistently managed to develop inside the figs of one backcross plant and also occasionally in a few figs from another backcross individual.
