Male trees contain female flowers with short styles. When an adult wasp is mature, it mates with another wasp within the syconium.
This fungus affects both males and females. The enlarged opening enables the females to leave the syconium in search of a new one where to oviposit. On the other hand, female flowers on female trees have long styles. Mutualism occurs between fig and fig wasps, which creates a need for specific species of figs to be pollinated by specific species of wasps.
The wasps breed inside the fig. These wasps lay fertilized eggs in the syconium of a F. Also, it is near impossible for wasps to emerge from a fig if they cannot perform oviposition.
The actual attractive substances come from the ostiole. This idea leads to the concept of fig-fig wasp mutualism. Fig endosepsis is not transmitted transovarily by the fig wasp. The wasps carry this disease on their wings and body. If the wasp does not detect a signal, it will not enter the fig.
Due to this rush, pollination will become less effective as more pollen falls off of the wasp bodies. The specific problem is: The fungus shows to be more evident in spring caprifigs that are pollinated with 5 to 10 winter caprifigs than when spring caprifigs are pollinated with only one winter caprifig.
Female wasps oviposit into the syconium for hatching. Blastophaga grossorum GravenhorstBlastophaga vaidi Joseph, Cynips psenes Linnaeus, There is also a difference in winter and spring caprifigs male figs and the time course for becoming available for receiving eggs and being pollinated. Winter, or delayed, caprifigs usually occur on male trees.
When wasps emerge from the syconium, they rush to the nearest syconia. The female then oviposits into a new syconium. It pollinates the common fig Ficus carica and the closely related Ficus palmata.
However, some ants do not respond to the odor of figs for different reasons. There is a major difference between male and female fig trees. This fig can only be pollinated by the symbiotic wasp who has retrieved pollen from another syconium.
The spring and winter caprifigs have a cycle related to each other as to maximize resources and output of figs and wasps.

This layering of ovipositing causes the larvae of P. Both of these genera pollinate Ficus species of figs. This section on cleptoparasitism needs attention from an expert in Biology. Instead, it will move on and search for another receptive fig. Then, males start enlarging the fig’s opening.

From there, the short life cycle of a B. Entomologia Experimentalis Et Applicata. This leads to the trend that female trees are lethal since wasps are stuck blastopyaga that syconium.
Once wasps emerge from the syconium, they have to figure out how to get to the fig in which they want to deposit their eggs. The wasps become contaminated with spores of the fungus as they contact plant surfaces upon emergence.
For instance, the fig could be a non-pollinator and therefore not release any chemical substance. Males emerge first and start seeking females to mate with.
The mother produces this hyperplastic tissue when she lays the eggs in the syconium.
Studies show that wasps on upper surfaces blastohpaga the leaves were infected with this fungus in higher levels than other wasps. Yet females’ wings and antennae detach as they enter the opening of a fig. When they oviposit, they are also pollinating that syconium.
