Maintenance of specificity in sympatric host-specific fig/wasp pollination mutualisms.

entered a low proportion of figs of the alternative host, and produced offspring in a small proportion of them. Despite differences in the VOC profiles of the two fig species, they included shared semiochemicals. Although females prefer receptive figs of , they are also attracted to those of . that entered male figs of produced offspring, as their ovipositors were long enough to reach the bottom of the style; however, broods were larger and offspring smaller than in the typical host. Female figs of failed to produce seeds when visited by . These findings advance our current understanding of how these species-specific mutualisms usually remain stable and the conditions that allow their diversification.
