and larvae eat fig wasps. Nematodes: Schistonchus laevigatus (Aphelenchoididae) is a plant-parasitic nematode associated with the pollinator Pegoscapus assuetus and syconia of F. citrifolia. Parasitodiplogaster laevigata is a parasite of the pollinator Pegoscapus assuetus. Mites: belonging to the family Tarsonemidae (Acarina) have been recognized in the syconia of F. aurea and F. citrifolia, but they have not been identified even to genus, and their behavior is undescribed. Midges: Ficiomyia perarticulata (Cecidomyiidae) oviposits in the walls of syconia of F. citrifolia, and the developing larvae induce the plant to form galls there. Rove beetles: Charoxus spinifer is a rove beetle (Coleoptera: Staphylinidae) whose adults enter late-stage syconia of F. aurea and F. citrifolia. Adults eat fig wasps; larvae develop within the syconia and prey on fig wasps, then pupate in the ground. Keystone species Ficus citrifolia is considered a tropical keystone species. Figs are a major component of the diets of more species of animals than any other tropical perennial fruit. Since F. citrifolia fruits year round many primates, birds and other species, feed exclusively on figs during seasons when other fruit is scarce. Additionally, the knobby, hollow, lattice-like trunk of this tree provides a home for thousands of invertebrates, rodents, bats, birds and reptiles. F. citrifolia is considered common and is not in danger of extinction. Genetic mosaics F. citrifolia may fuse with figs of other species types, creating a cumulate tree that is a genetic mosaic. Research suggests that the frequency of genetic mosaicism among strangler figs may be quite high; it is unknown how this variation effects flowering in mosaic figs. (Thomson et al., 1995). Thomson et al. suggest that if genetically different segments of a single tree flower asynchronously, agaonid wasp populations may be more resistant to low host population sizes that previously thought. Alternatively, genetic mosaicism could mean that the number of certain varieties of fig in an ecosystem may be far lower than biologists have previously thought, and given populations may not have enough trees to maintain their symbiotic relationship with their pollinating wasps. History One theory is that the Portuguese name for F. citrifolia, "Os Barbados", gave Barbados its name. It appears on the coat of arms of Barbados, and the removal of one specimen, over 100 years old, was enough to draw attention. Medicine An extract of F. citrifolia may have therapeutic value for chemotherapy patients. References How to be a Fig, Daniel
