The number of offspring is low when the entry number of wasps in a syconium is high. One blasrophaga the main predators of these wasps is ants.
All female flowers on male tree with ovaries that are not parasitized with wasp eggs will produce seeds and will help pollination and reproduction of that flower. They know that most fig wasps are located on male fig trees, so they use that relationship to prey on wasps.
They do this by holding up their heads and antennae next to the opening of the syconium the ostiole.

This fungus affects blastopgaga males and females. Blastophaga grossorum GravenhorstBlastophaga vaidi Joseph, Cynips psenes Linnaeus, Blastophaga psenes is a wasp species in the genus Blastophaga. Retrieved 20 April Views Read Edit View history. Proceedings of the Royal Society B: All female flowers on male trees with parasitized ovaries with wasp eggs produce larva and no seeds.
The Introduction of Blastophaga Psenes into California. There is a major difference between male and female fig trees.
Uses authors parameter Articles with ‘species’ microformats Articles needing expert attention from February All articles needing expert attention Biology articles needing expert attention.
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.
Figs emit compounds that the wasps can sense. The more wasps that pass through one ostiole, the more likely the wasp will contract F. These wasps’ native range is in the Palaearctic, including Southern Europe near the Mediterranean Basin.

Because this nematode is primarily found in the hemocoel of a female wasp, males are not associated with nematodes. Sometimes blaastophaga occurs before the female has finished emerging from its cocoon. They have no wings and die shortly after.
After fertilization, females emerge from a syconium with nematodes still in hemocoel along with pollen flakes along her body. Archived from the original on 27 April Studies show that wasps on upper surfaces of the leaves were infected with this fungus in higher levels than other wasps. These wasps lay fertilized eggs in the syconium of a F. In the case of B.
Blastophaga – Wikipedia
In the phylogenetic tree, the genus of Blastophaga and Wiebesia are very similar. This olfactory stimulus is specific for the wasps’ host fig in this case, F. For instance, the fig could be a non-pollinator and therefore not release any chemical substance. Males blastophwga first and start seeking females to mate with. Mutualism occurs between fig and fig wasps, which creates a need for specific species of figs to be pollinated by specific species of wasps.
In the case where the ants cannot detect odors, the wasps will not be predated upon.

This leads to the psnes that female trees are lethal since wasps are stuck in that syconium. Fig endosepsis is not transmitted transovarily by the fig wasp.
When wasps emerge from the syconium, they rush to the nearest syconia.
