Syconium - Wikipedia
The tight ostiolar enclosure at the syconium's apex makes it highly pollinator-specific. When receptive to pollen, the ostiole slightly loosens, allowing the highly specialized wasps to enter through it.
Secretory structures at syconia and flowers of Ficus enormis …
2013年1月1日 · Syconia are sessil and subsessil, with a pair of rounded and persistent basal bracts, a globous to elliptical green receptacle (1 or 2 cm diameter) with white spots, and an ostiole with 2–3 mm diameter (Berg and Vilaviccencio, 2004), that …
The roles of the ostiole in the fig-fig wasp mutualism from a …
2022年10月20日 · Also, for the first time in Ficus, we found that the syconia basal bracts completely covered the ostiole during the receptive phase of the syconia of F. isophlebia. Thus, these bracts act as an additional physical barrier to pollinating wasps.
Frontiers | Interactions Between Figs and Gall-Inducing Fig Wasps ...
2021年8月9日 · Those entering through the ostiole are usually unable to re-enter other syconia owing to injuries sustained during ostiolar passage while those ovipositing from outside could deposit eggs in multiple syconia.
Mutualists with attitude: coevolving fig wasps and figs
2003年5月1日 · Female wasps enter receptive syconia through a narrow tunnel called the ostiole and then pollinate the female flowers. However, they also oviposit into some fig ovaries ( Fig. Ic ), which are galled by the wasp larvae.
Secretory structures at syconia and flowers of Ficus enormis …
2013年1月1日 · The ostiole is a key structure in the reproductive biology of the Ficus because it is the access entry of pollinating agents (Hymenoptera, Agaonidae subfamily) of the flowers. In addition, it traps the wasp in the inflorescence until the moment the larvae are hatching.
Phenology and pollinating wasp dynamics of Ficus microcarpa L.f ...
With the small amount of local pollinators from the winter syconia and potential immigrating foundresses from other populations, the pollinator population size can increase very quickly from almost zero to over 40,000 wasps for this 29-tree local population within a season.
Secretory structures at syconia and flowers of Ficus enormis …
2013年1月31日 · We describe the zones that compose the ostiole, which support the hypothesis that the ostiole is a selective filter in the interactions of fig trees with Agaonidae fig wasps.
Phylogeny and evolution of life-history strategies in the …
2011年6月22日 · Most species of NPFW oviposit from outside the syconium but some species enter receptive syconia through a narrow tunnel called the ostiole and oviposit in the flowers from inside the syconium. The biology of NPFW are poorly known and few detailed studies have reported reliable observations.
The cycle of syconium development in Ficus elastica and an …
Phase A, The ostiole (opening) of the green syconium is tightly closed by overlapping bracts and entrance scales. Phase B, Female flowers are matured and female pollinators enter the syconium...
