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. Retrieved 11 October Entomologia Experimentalis Et Applicata.
They know that most fig wasps are located on male fig trees, so they use that relationship to prey on wasps. Retrieved 20 April Male trees contain female flowers with short styles. These nematodes then invade, feed, and reproduce inside the floret tissues.
Female wasps oviposit into the syconium for hatching. The actual attractive substances come from the ostiole.
This fungus affects both males and females. The wasps blwstophaga this disease on their wings and body. Mutualism occurs between fig and fig wasps, which blastophava a need for specific species of figs to be pollinated by specific species of wasps. Also, it is near impossible for wasps to emerge from a fig if they cannot perform oviposition. Wasps who were higher up in the tree or further out on a branch also showed more fungus on their wings and bodies.
Each species of fig is pollinated by a specific species of fig wasp. Uses authors parameter Articles with ‘species’ microformats Articles needing expert attention from February All articles needing expert attention Biology articles needing expert attention.
The wasps assess the figs before entrance. 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. Spring, or undelayed, caprifigs usually occur on female trees. The American Phytopathological Society.
Due to this rush, pollination will become less effective as more pollen falls off of the wasp bodies. They do this by holding up their heads and antennae next to the opening of the syconium the ostiole.
Blastophaga – Wikipedia
This concept is called associative learning of odor because the ants are indirectly finding these wasps by associating the smell of the fig with the wasps. Due to the difference in male and female trees, male tree figs are more attractive than female tree figs as caused by selection.
As previously stated, B. Then, males start enlarging the fig’s blaztophaga. On the other hand, female flowers on female trees have long styles.
There is a major difference between male and female fig trees.
When they oviposit, they are also pollinating that syconium. It pollinates the common fig Ficus carica and the closely related Ficus palmata. Blastophaga psenes is a wasp species in the genus Blastophaga. The wasps become contaminated with spores of the fungus as they contact plant surfaces upon emergence.
In the case where the ants cannot detect odors, the wasps will not be predated upon. When they are hatched, B. This page was last edited on 14 Novemberat The origin of mutualism is also the beginning of the fig wasp phylogeny. Winter, or delayed, caprifigs usually occur on male trees.
When wasps emerge from the syconium, they rush to the nearest syconia. Fig Ficus carica, Moraceae. Some wasps can carry a disease that is carried by F.

For instance, the fig could be a non-pollinator and therefore not release any chemical substance. From there, the short life cycle of a B. Archived from the original on blastophaag April
