Fundamental and Applied Nematology. Sometimes mating occurs before the female has finished emerging from its cocoon. Then, males start enlarging the fig’s opening. This page was last edited on 14 Novemberat Fig endosepsis is not transmitted transovarily by the fig wasp. The number of offspring is low when the entry number of wasps in a syconium is high. Proceedings of the Royal Society B: 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.

By being a cleptoparasite, P. The female then oviposits into a new syconium. Blastophaga grossorum GravenhorstBlastophaga vaidi Joseph, Cynips psenes Linnaeus, One of the main predators of these wasps is ants.

The actual attractive substances come from the ostiole. Also, it is near impossible for wasps to emerge from a fig if blawtophaga cannot perform oviposition.

There is a major difference between male and female fig trees. Yet females’ wings and antennae detach as they enter the opening of a fig. Instead, it will move on and search for another receptive fig. Because this nematode is primarily found in the hemocoel of a female wasp, males are not associated with nematodes.


Psenex there, the short life cycle of a B. In the case where the ants cannot detect odors, the wasps will not be predated upon. This fungus affects both males and females. In the case of B. The Netherlands Entomological Society. WikiProject Biology may be able to help recruit an expert. The more wasps that pass through one ostiole, the more likely the wasp will contract F.

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

This idea leads to the concept of fig-fig wasp mutualism. The spring and winter caprifigs have a cycle related to each other as to maximize resources and output of figs and wasps.

Winter, or delayed, caprifigs usually occur on male trees. Male trees contain female flowers with short styles. This section on cleptoparasitism needs attention from an expert in Biology. The larvae become adults around the same time male fig flowers are ready to produce pollen. The ants use psrnes fig-fig wasp mutualism to find the fig wasps by detecting an odor that comes from the figs of the male trees.

Mating occurs within the syconium and laying eggs occurs in a syconium different than the one where mating occurred. This also implies that the fig wasp population is much more active and larger in the spring. By using this site, you agree to the Terms of Use and Privacy Policy. In the phylogenetic tree, the genus of Blastophaga and Wiebesia are very similar. Some fall from the fig to the ground.


Blastophaga – Wikipedia

Agaonidae Pollinator Hymenoptera Insects described in If a wasp detects the signal, it bastophaga lower its antennae and will search blwstophaga the entrance to the fig. Retrieved 26 May They do this by holding up their heads and antennae next to the opening of the syconium the ostiole. Upon sensing these signals from a specific syconium, the wasp will approach that fig. These wasps’ native range is in the Palaearctic, including Southern Europe near the Mediterranean Basin.

Later, the female lays its eggs in the ovaries of another fig by sticking its ovipositor in each flower’s style. However, some ants do not respond to the odor of figs for different reasons. It pollinates the common fig Ficus carica and the closely related Ficus palmata.

When these larvae emerge as adults, they carry pollen that they accumulated in the syconium out of the fig. This layering of ovipositing causes the larvae of P. Blastophaga psenes Scientific classification Kingdom: Due to blzstophaga rush, pollination will become less effective as more pollen falls off of the wasp bodies.

When wasps emerge from the syconium, they rush to the nearest syconia. Pentane extracts from figs which are in their receptive-phase will attract B.
