There is a major difference between male and female fig trees.

This idea leads to the concept of fig-fig wasp mutualism. The fungus shows to be more evident in spring caprifigs that are pollinated with 5 blastopuaga 10 winter caprifigs than when spring caprifigs are pollinated with only one winter caprifig. Because female trees are lethal, wasps prefer these delayed caprifigs of male trees.
The wasps become contaminated with spores of the fungus as they contact plant surfaces upon emergence. Once wasps emerge from the blastophzga, they have to figure out how to get to the fig in which they want to deposit their eggs. Blastophaga grossorum GravenhorstBlastophaga vaidi Joseph, Cynips psenes Linnaeus, Agaonidae Pollinator Hymenoptera Insects described in Figs emit compounds that the wasps can sense.

This led to the conclusion that contamination increases as the wasps walk on leaves, petioles, and fruits before they reach the opening to the syconium. A Study of Ficus carica L. If the wasp does not detect a signal, it will not enter the fig.
Views Read Edit View history. From Wikipedia, the free encyclopedia. When they oviposit, they are also pollinating that syconium. However, some ants do not respond to bkastophaga odor of figs for different reasons. WikiProject Biology may be able to help recruit an expert. This layering of ovipositing causes the larvae blastophagz P.
Winter, or delayed, caprifigs usually occur on male trees. By being a cleptoparasite, P. If a wasp detects the signal, it will lower its antennae and will search for the entrance to the fig. Yet females’ wings and antennae detach as they enter the opening of a fig.
These nematodes then invade, feed, and reproduce inside the floret tissues. Upon sensing these signals from a specific syconium, the wasp will approach that fig.
From there, the short life cycle of a B. Proceedings of the Royal Society B: The wasps assess the figs before entrance.
The enlarged opening enables the females to leave the syconium in search of a new one where to oviposit. Blastophaga psenes Scientific classification Kingdom: Later, the female lays its eggs in the ovaries of another fig by sticking its ovipositor in each flower’s style. Both smell and taste also help actual entrance into a fig once the desired fig has been located. All female flowers on male trees with parasitized ovaries with wasp eggs produce larva and no seeds.
This leads to the trend that female trees are lethal since wasps are stuck in that syconium.
Archived from the original on 27 April When the larvae hatch, they develop in the fig ovariescreating a gall. Fig endosepsis is not transmitted transovarily by the fig wasp.
One of the main predators of these wasps is ants.
