Retrieved 26 May The larvae become adults around the same time male fig flowers are ready to produce pollen. Retrieved 11 October The spring and winter caprifigs have a cycle related to each other as to maximize resources and output of figs and wasps.

Blastophaga psenes

Proceedings of the Royal Society B: This can lead to some flowers not being pollinated because some styles are too long. The wasps carry this disease on their wings and body. Views Read Edit View history. In the phylogenetic tree, the genus of Blastophaga and Wiebesia are very similar. This layering of ovipositing causes the larvae of P. The female then oviposits into a new syconium. 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.

Upon sensing these signals from a specific syconium, the wasp will approach that fig. Uses authors parameter Psends with ‘species’ microformats Articles needing expert attention from February All articles needing expert attention Biology articles needing expert attention.


Because of this lack of depositing eggs in these female flowers, all female flowers on female trees produce seeds and none produce larva. One of the main predators of these wasps is ants. Males emerge first and start seeking females to mate with.

The ants use the fig-fig wasp mutualism to find the fig wasps by detecting an blastopahga that comes from the pseness of the male trees.

The origin of mutualism is also the beginning of the fig wasp phylogeny. The mother produces this hyperplastic tissue when she lays the eggs in the syconium.

By being a cleptoparasite, P. Blastophaga psenes Linnaeus[1].

When an adult wasp is mature, it mates with another wasp within the syconium. These wasps’ native range is in the Palaearctic, including Southern Europe near the Mediterranean Basin. The wasps breed inside the fig.

Larvae finish development with nematode still inside the hemocoel. The wasps become contaminated with spores of the fungus as they contact plant surfaces upon emergence. Sometimes mating occurs before the female has finished emerging from its cocoon. This idea leads to the concept of fig-fig wasp mutualism. This rush creates a large number of wasps all competing to enter an adjacent syconium.

Blastophaga psenes – Wikipedia

Male trees contain female flowers with short styles. Mating occurs within the syconium and laying eggs occurs in a syconium different than the one where mating occurred. Linnaeus[1]. Each species of fig is pollinated by a specific species of fig wasp.


In the case of B. The more wasps that pass through one ostiole, the more likely the wasp will contract F. It pollinates the common blaetophaga Ficus carica and the closely related Ficus palmata. After mating, females emerge from pssnes fig and search for a new nearby fig in which to lay their eggs. They do this by holding up their heads and antennae next to the opening of the syconium the ostiole.

Mutualism occurs between fig and fig wasps, which creates a need for specific species of figs to be pollinated by specific species of wasps. For instance, the fig could be a non-pollinator and therefore not release any chemical substance. This leads to the trend that female trees are lethal since wasps are stuck in that syconium. In other projects Wikimedia Commons Wikispecies. These wasps lay fertilized eggs in the syconium of a F.

This also implies that the fig wasp population is much more active and larger in the spring.
