The number of offspring is low when the entry number of wasps in a syconium is high. The mother produces this hyperplastic tissue when she lays the eggs in the syconium. This fig can only be pollinated by the symbiotic wasp who has retrieved pollen from another syconium. WikiProject Biology may be able to help recruit an expert. One of the main predators of these wasps is ants. The more wasps that pass through one ostiole, the more likely the wasp will contract F.

Wasps usually oviposit into a nearby syconium. This idea leads to the concept of fig-fig wasp mutualism. The origin of mutualism is also the beginning of the fig wasp phylogeny.

They do this by holding up their heads and antennae next to the opening of the syconium the ostiole. Larvae finish development with nematode still inside the hemocoel. They have no wings and die shortly after. Some fall from the fig to the ground.


Also, the incidences of this fungus are higher when there is a high population of wasps with limited figs. By being a cleptoparasite, P.

For instance, the fig could be a non-pollinator and therefore not release any chemical substance. The wasps carry this disease on their wings and body. Mating occurs within the syconium and laying eggs occurs in a syconium different than the one where mating occurred. From there, the short life cycle of a B. After fertilization, females emerge from a syconium with nematodes still in hemocoel along with pollen flakes along her body. Some wasps can carry a disease that is carried by F.

Female wasps oviposit into the syconium for hatching. Males emerge first and start seeking females to mate with.

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.

The spring and winter caprifigs have a cycle related to each other as to maximize resources and output of figs and wasps. Uses authors parameter Articles with ‘species’ microformats Articles needing expert attention from February All articles needing expert attention Biology articles needing expert attention. Spring, or undelayed, caprifigs usually occur on female trees. The specific problem is: A Study of Ficus carica L.


Then, males start enlarging the fig’s opening.

This layering of ovipositing causes the larvae of P. From Wikipedia, the free encyclopedia. Each species of fig blastophaha pollinated by a specific species of fig wasp. Because this nematode is primarily found in the hemocoel of a female wasp, males are not associated with nematodes.

The enlarged opening enables the females to leave the syconium in search of a new one where to oviposit.

Blastophaga psenes

Views Read Edit View history. This rush creates a large number of wasps all competing to enter an adjacent syconium. Because these wasps have such short lives, selection has favored this attraction towards receptive plants to be easily distinguishable from a few meters.

In the phylogenetic tree, the genus of Blastophaga and Wiebesia are very similar. The larvae become adults around the same time male fig flowers are ready to produce pollen. Linnaeus[1].
