Characterisation of the fig-fig wasp holobiont
BioSystemsPlants and animals have long been considered distinct kingdoms, yet here a 'plant-animal' is described. An extraordinary symbiosis in which neither organism can reproduce without the other, the fig tree (Ficus) provides the habitat for its exclusive pollinator: the fig wasp (Agaonidae).

Seed and wasp production in the mutualism of figs and fig wasps
Forestry Studies in China, 2005Figs (Moracea: Ficus) and fig wasps (Hymenoptera: Chlocloids: Agaonideae) depend on each other to complete their reproduction. Monoecious fig species and their pollinating wasps are in conflict over the use of fig ovaries which can either produce one seed or one wasp. From observation on Ficus virens Ait., we showed that female flowers with outer layer

How to be a fig wasp parasite on the fig–fig wasp mutualism
Current Opinion in Insect Science, 2015The nursery pollination mutualism between figs and pollinating fig wasps is based on adaptations that allow wasps to enter the enclosed inflorescences of figs, to facilitate seed set, and to have offspring that develop within the nursery and that leave to enter other inflorescences for pollination.

Annual Review of Entomology, 2002
▪ Abstract In the two decades since Janzen described how to be a fig, more than 200 papers have appeared on fig wasps (Agaonidae) and their host plants (Ficus spp., Moraceae). Fig pollination is now widely regarded as a model system for the study of coevolved mutualism, and earlier reviews have focused on the evolution of resource conflicts between ...

Vicious fig wasps in viscous populations
Trends in Ecology & Evolution, 2001Understanding when interacting individuals should conflict or cooperate is an enduring topic in evolutionary ecology. Cooperation can be favoured through kin selection when those interacting are genetic relatives. Because high levels of relatedness can be generated in ‘viscous’ populations, characterized by limited dispersal, it has often been assumed ...

Sequential ovipositing in fig wasps
2023This dataset is presented in Ms Excel.The data is about foundress counts that distinguishes between females that are alive, dead and moribund for 5 fig crops of four fig wasp species from Pretoria, South Africa.

Mutualists with attitude: coevolving fig wasps and figs
Trends in Ecology & Evolution, 2003The intimate mutualism between fig wasps and figs has long captivated biologists, and new phylogenies are now uncovering its evolutionary history. Fig-pollinating wasps evolved just once, but fig parasitism has evolved repeatedly and convergently. Figs and their pollinators appear to have co-speciated considerably, but not invariably, because the ...

Biotropica, 1988
Predators inflict high mortality on the four species of wasps associated with the fig Ficus pertusa L. in Monteverde, Costa Rica. Because one of these wasps is the obligate pollinator of the fig, predation may have a strong impact on successful pollen donation by the plant.

How to be a fig wasp down under: The diversity and structure of an Australian fig wasp community
Acta Oecologica, 2014Endophytic insects and their parasitoids provide valuable models for community ecology. The wasp communities in inflorescences of fig trees have great potential for comparative studies, but we must first describe individual communities. Here, we add to the few detailed studies of such communities by describing the one associated with Ficus rubiginosa ...

Sex Ratio Adjustment in Fig Wasps
Science, 1985The effects of inbreeding and local mate competition have often been confounded in theoretical and empirical studies of sex ratio. A general model considering the interplay of their influences on sex ratio evolution is presented, and its predictions are compared with data collected from three fig wasp species. The results indicate that female fig wasps
