If the wasp does not detect a signal, it will not enter the fig. Because these wasps have such short lives, selection has favored this attraction towards receptive plants to be easily distinguishable from a few meters.

Sometimes mating occurs before the female has finished emerging from its cocoon. Also, it is near impossible for wasps to emerge from a fig if they cannot perform oviposition.

Mutualism occurs between fig and fig psenees, which creates a need for specific species of figs to be pollinated by specific species of wasps. Uses authors parameter link. These wasps lay fertilized eggs in the syconium of a F. If a wasp detects the signal, it will lower its antennae and will search for the entrance to the fig.

Blastophaga – Wikipedia

Fig endosepsis is not transmitted transovarily by the fig wasp. All female flowers on male trees with parasitized ovaries with wasp eggs produce larva and no seeds. Winter, or delayed, caprifigs usually occur on male trees.

Blastophaga psenes

The specific problem is: The spring and winter caprifigs have a cycle related to each other as to maximize resources and output of figs and wasps. Wasps who were higher up in the tree or further out on a branch also showed more fungus on their wings and bodies. While the nematodes as parasites are not lethal to B. In the case of B.

After fertilization, females emerge from a syconium with nematodes still in hemocoel along with pollen flakes along her body. 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.

In the case where the ants cannot detect odors, the wasps will not be predated upon. 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. Entomologia Experimentalis Et Applicata. When these larvae emerge as adults, they carry pollen that they accumulated in the syconium out of the fig.

It pollinates the common fig Ficus carica and the closely related Ficus palmata. This page was last edited on 14 Novemberat The larvae become adults around the same time male fig flowers are ready to produce pollen. Proceedings of the Royal Society B: From Wikipedia, the free encyclopedia.

Due to the fact that wasps do not have very long ovipositors, they can only parasitize ovaries of these female flowers with short styles which are only found on male trees. Then, males start enlarging the fig’s opening.

This section on cleptoparasitism needs attention from an expert in Biology. Wasps usually oviposit into a nearby syconium.

This leads to the trend that female trees are lethal since wasps are stuck in that syconium. Archived from the original on 27 April After mating, females emerge from the fig and search for a new nearby fig in which to lay their eggs.

The enlarged opening enables the females to leave the syconium in search of a new one where to oviposit. Yet females’ wings and antennae detach as they enter the opening of a fig. Fundamental and Applied Nematology. This concept is called associative learning of odor because the ants are indirectly finding these wasps by associating the smell of the fig with the wasps. They know that most fig wasps are located on male fig trees, so they use that relationship to prey on wasps.

When wasps emerge from the syconium, they rush to the nearest syconia. Instead, it will move on and search for another receptive fig. Mating occurs within the syconium and laying eggs occurs in a syconium different than the one where mating occurred.

The wasps breed inside the fig.
