Investigating Fig Wasps: Uncovering the Concealed Ecosystem Inside Your Figs and the Role Insects Play in Their Production
In the heart of nature's intricate web, a unique relationship unfolds between fig trees and fig wasps. This symbiotic alliance, which has been thriving for approximately 80 million years, is a testament to the wonders of evolution.
Fig trees, such as the Smyrna and Calimyrna, rely on specific fig wasps for pollination. These wild figs, unlike their store-bought counterparts, host these tiny insects as part of their life cycle. In return, the figs provide a haven for the wasps, ensuring the continuation of their species.
The life cycle of fig wasps is remarkably tied to the growth of figs. Female fig wasps lay their eggs in ripe figs, shed their wings, and squeeze in through the tiny openings. After pollinating the figs, they die, but their sacrifice is not in vain. The fig's enzyme, ficain, breaks down the wasp's body into plant food, nourishing the fig and aiding in the development of seeds.
Male fig wasps, on the other hand, mate with the females and chew tunnels to the outside so the females can leave the fig and continue the life cycle.
The edible fig, Ficus carica, is pollinated by the Blastophaga psenes wasp. Each type of fig has a specific wasp that is suited to pollinate it. Around 850-900 wasp species work with wild figs, each one suited to its specific tree.
Not all fig trees require wasps for pollination. Varieties like 'Brown Turkey' and 'Celeste' are parthenocarpic, meaning they can produce fruit without pollination. Another example is the dwarf fig tree, 'Little Miss Figgy', which can be grown indoors with ease.
Fig trees are adaptable and can be grown in cooler climates. They can even be container-grown and moved indoors as needed. For those living in USDA zone 5, the 'Chicago Hardy' fig tree is a hardy option, available at Fast Growing Trees.
This mutualistic relationship between figs and fig wasps is a captivating example of nature's harmony. It serves as a reminder of the intricate connections that exist within our ecosystem and the vital roles that even the smallest creatures play.
