Figs are unique in their pollination process since they depend on a special kind of wasp that is only found within the fig’s species. The female wasp enters the closed fig, lays her eggs, and then dies inside while pollen from male flowers gets trapped there with her. When the larvae hatch, they feed on the fleshy fruit and carry out what’s known as ‘fig wasp mutualism’ – by eating their way out, they inadvertently spread pollen to other female flowers so that seeds can form. In return for providing food for these insect offspring, the plant ensures its survival through pollination!
So why is this special relationship so important? It ensures a steady food supply for both parties involved and helps protect against environmental stressors that could disrupt natural pollination processes, such as extreme weather or insect predators. In short, without this symbiotic union between fig trees and fig wasps, the species would not be able to survive!
How many wasps are in a fig?
The number of wasps in a fig can vary depending on the species. Generally, female wasps lay their eggs inside the closed fig and then die there – so a single fig may contain multiple larvae from one or more female wasps. Additionally, some species of figs are pollinated by male and female wasps, meaning they could contain dead and living insects at any given time.
Can figs be pollinated without fig wasps?
Yes, figs can be pollinated without the help of fig wasps. For instance, some varieties can self-pollinate or use wind and other insects for fertilization. Additionally, humans have also developed techniques to pollinate certain species of figs artificially. However, this is less effective than using a natural process like mutualism with fig wasps and may even reduce the quality of fruit the tree produces.
How to pollinate figs by hand?
To pollinate figs by hand, you will need a soft brush and some pollen. To begin, remove the male flowers from the tree and place them in a container. Then use your brush to collect pollen from these blooms before transferring it to the female flowers of the same species on another tree. Finally, close up any open buds with your fingers to prevent contamination or loss of pollen, ensuring that the fertilization process is successful!
How To Hand Pollinate Figs With A Hypodermic Needle?
Hand-pollinating figs with a hypodermic needle is a relatively advanced technique that requires precision and skill. Start by removing the male flowers from your tree and placing them in an open container. Then use the needle to collect pollen before transferring it directly into the female flowers of another tree. Finally, ensure that each bloom has been properly fertilized by using your fingers to close up any open buds on both trees.
Does every fig have a dead wasp inside?
No, not every fig contains a dead wasp inside. While many species rely on these insects’ pollinating and fertilizing services, some varieties can be self-pollinated or use other methods for reproduction. Additionally, even when fig wasps pollinate figs, only female wasps will enter the fruit and lay their eggs – so depending on the species, there may not always be a dead insect involved in the process. Don’t worry; by the time you slice a fig to add to your morning yogurt, the enzyme ficain has already worked its magic, breaking down the bug into tiny particles, ensuring that any remnants are (at least mostly) dissolved.
Which fig varieties need a wasp for pollination, and which use self-pollination?
Most of the figs sold in the markets belong to Parthenocarpy varieties, that is, those that are not pollinated by wasps but by self-pollination. These figs include ‘Mission’, ‘Celeste’, ‘Brown Turkey’, and ‘Brunswick’, which don’t need wasps for pollination.
At the same time, some fig varieties (some say they are tastier…) need a wasp so that the syconium (fig flower) turns into a fruit. These figs are called: “Caducous” figs, including ‘Calimyrna’, ‘Marabout’ and ‘Smyrna’, which require a minute wasp to enter and perform pollination within the fruit.
How do fig trees self-pollinate?
Fig trees self-pollinate by relying on the wind to move pollen from the male flowers to receptive female flowers in their inflorescences. This process is known as anemophilous pollination. It increases the chances of successful reproduction for fig trees since it does not require insects or other animals to assist with cross-pollination.
How to encourage fig trees to pollinate themselves?
There are several steps you can take to encourage fig trees to self-pollinate. First, ensure the tree is planted in a location that receives ample wind; this will help disperse pollen from the male flowers to receptive female flowers. Additionally, prune away branches or foliage blocking airflow around the tree and reducing competition for pollinators. Finally, watch for signs of insect pests or diseases and address them as soon as possible – these can interfere with successful pollination if left untreated!
How many wasps are in a fig?
The number of wasps in a fig can vary depending on the species.

Additionally, some species of figs are pollinated by male and female wasps, meaning they could contain dead and living insects at any given time.
What causes a fig tree not to bear fruit?
As mentioned above, in some varieties A fig tree may only bear fruit if it is receiving adequate pollination. This could be due to a lack of available insects, an absence of male flowers, or environmental factors such as drought that can decrease insect activity and reduce the chances of successful pollination. Additionally, suppose the female wasp fails to enter a closed fig and lay her eggs. In that case, no larvae will be present to help spread pollen – meaning that fruit production may still be hindered even with good insect activity.
In cases where a fig tree is not bearing fruit, it can be beneficial to provide supplemental pollination. This could involve introducing different species of wasps or other insects known to help with fig pollination and creating ideal environmental conditions for these insects, such as providing water or shelter. Additionally, if the problem is due to a lack of male flowers, then pruning and fertilizing techniques may encourage more blooms.
