One of the main predators of these wasps is ants. This fig can only be pollinated by the symbiotic wasp who has retrieved pollen from another syconium. Once wasps emerge from the syconium, they have to figure out how to get to the fig in which they want to deposit their eggs. Fig Ficus carica, Moraceae. Blastophaga psenes is a wasp species in the genus Blastophaga.
There is a major difference between male and female fig trees. From there, the short life cycle of a B.
Each species of fig is pollinated by a specific species of fig wasp. Archived from the original on 27 April Retrieved 11 October 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.
The Introduction of Blastophaga Psenes into California. Uses authors parameter link. These wasps’ native range is in the Palaearctic, including Southern Europe near the Mediterranean Basin.
Blastophaga psenes – Identical Protein Groups Result
When they are hatched, B. They have no wings and die shortly after. While the nematodes as parasites are not lethal to B. Blastophagga of this lack of depositing eggs in these female flowers, all female flowers on female trees produce seeds and none produce larva.
Wasps who were higher up in the tree or further out on a blastopaga also showed more fungus on their wings and bodies. 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.
Later, the female lays its eggs in the ovaries of another fig by sticking its ovipositor psenew each flower’s style. This page was last edited on 14 Novemberat Winter, or delayed, caprifigs usually occur on male trees. The Netherlands Entomological Society. The wasps become contaminated with spores of the fungus as they contact plant surfaces upon emergence. They do this by holding up their heads and antennae next to the opening of the syconium the ostiole.
This can lead to some flowers not being pollinated because some styles are too long.
All female flowers on male trees with parasitized ovaries with wasp eggs produce larva and no seeds. The mother produces this hyperplastic tissue when she lays the eggs in the syconium. Fundamental and Applied Nematology. Mutualism occurs between fig and fig wasps, which creates a need for specific b,astophaga of figs to be pollinated by specific species of wasps.
Also, the incidences of this fungus are blastophagw when there is a high population of wasps with limited figs. The wasps carry this disease on their wings and body.
Fig endosepsis is not transmitted transovarily by the fig wasp. Each larva from a deposited egg destroys a female flower when it feeds on its growing seed.
Because the fungus grows on the ostiole, the fungus is transmitted to the wasps’ bodies when the wasp emerges from the syconium through the ostiole. Because female trees are lethal, wasps prefer these delayed caprifigs of male trees. From Wikipedia, the free encyclopedia. Linnaeus. Retrieved from ” https: A Study of Ficus carica L.

Due to the difference in male and female trees, male tree figs are more attractive than female tree figs as caused by selection. This fungus affects both males and females.

This idea leads boastophaga the concept of fig-fig wasp mutualism. 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. Some wasps can carry a disease that is carried by F. Due to this rush, pollination will become less effective as more pollen falls off of the wasp bodies. By being a cleptoparasite, P. The more wasps that pass through one ostiole, the more likely the wasp will contract F.
