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

Fig wasps cannot exist by themselves. They live in a close and obligate symbiosis with the figs (Ficus) in the sycones of which they breed, each species of wasp with its own species of fig. The figs are totally dependent on these wasps of the hymenopterous family Agaonidae, which are the sole agents for the pollination of the flowers hidden in their ...

Fig Wasps: Mechanism of Pollen Transfer
Science, 1969The fig ( Ficus ) is absolutely dependent upon pollination by minute agaonid wasps for development of fertile seeds. In some species of the wasp genera Agaon , Allotriozoon , Blastophaga , Ceratosolen ...

Journal of Biogeography, 1996
Abstract. Figs host three ecologically distinct groups of wasps: pollinators, non‐pollinators (parasitic wasps) and parasitoids. Both pollinators and non‐pollinators complete their life cycles using fig tissue, while parasitoids appear to attack some groups of non‐pollinators.

Molecular phylogeny of fig wasps Agaonidae are not monophyletic
Comptes Rendus de l'Académie des Sciences - Series III - Sciences de la Vie, 1998According to the present classification, the family Agaonidae contains all fig pollinators as well as five subfamilies of non-pollinating fig wasps. The molecular phylogeny of the family was reconstructed using partial sequences of the 28S rRNA (D1 and D2 domains). Our results show that the family Agaonidae is not monophyletic.

Figs and fig wasps: evolution in a microcosm.
Biologist (London, England), 2001Fig wasps are tiny insects that both pollinate and feed upon fig plants. Each species requires the other in order to complete its reproductive cycle. The interaction centres on the unique structure of syconium (fig inflorescence), which provides an intriguing and convenient microcosm for studying the action of both natural and sexual selection.

Weapons and fighting in fig wasps
Trends in Ecology & Evolution, 1987trypesis caricae, a species in the same genus as the wasp studied by Murray; the numerals 8 and 9 show the elongated eighth and ninth abdominal segments, followed posteriorly by the long sheaths that hold the ovipositor, which is used to drill through the outside wall of the fig into the ovaries of the pistillate florets inside.
