Parasitoid Wasp uses its long egg-laying tube to pierce the outside of the fig and lay its eggs into the ovules inside the fruits.

The egg-laying tube is an organ set of two in one : OUTER Tube (Dorsal valve) and INNER Tube (Ventral valve)
The tube that actually pierced into the fruit is the INNER Tube while the OUTER Tube remain outside the fruit.

This diagram show the OUTER Tube (Dorsal valve) and INNER Tube (Ventral valve) of a Ovipositor of a female wasp of Ficus cumingii during an ovipositing event.

This is a female Parasitoid wasp.

The OUTER Ovipositor does not pierced through the fruit skin. Instead it is the much soft  thinner INNER Ovipositor was inserted into the fruits.
The OUTER and harder Ovipositor served as a searcher, protector and guide to the INNER Ovipositor.

As the INNER Tube gets deeper into the fruit, it has to exposed more from covering OUTER tube

The INNER Tube is now half exposed from the OUTER Covering indication this tinny tube has gone deeper into the fruit.

The INNER Tube is now firmly anchored to the fruit and the OUTER tube is not in need now. The OUTER and INNER Tubes separated.

As the INNER Tube gets deeper into the fruit, it has to exposed more from the limited length from the covering OUTER tube
The legs and body moved nearer toward the inserting point allowing more space and length to the INNER Tube.

The INNER Tube is now half inserted in the fruit.

Beginning the insert with 45 degree upward, the female wasp now gradually lower the abdomen to horizontal level allowing the INNER Tube an almost vertical position to the fruit.

Body Horizontal, INNER Tube almost Vertical. OUTER Tube stabilizing the abdomen by anchoring on the fruit.
At this position, this female wasp remain still for several seconds. During this several seconds an egg is successfully laid.

This Non-Pollinating Fig Wasp emerged from another matured fruit from the same tree and very soon ovipositing in a green/pinkish fruit on the same tree.

Non-Pollinating Fig Wasp lay eggs from outside the fig fruits.

These wasps use an appendage, the Ovipositor, to pierce straight through the fig's skin and inject their own eggs, which then develop in place of the fig's seeds or the pollinating wasp eggs themselves.

The above is a Non-Pollinating Wasp.  There are two Non-Pollinating Wasp recorded from this male tree.
However no Pollinating Fig Wasp from this male tree is recorded yet.

Two thirds of Borneo’s wild figs are dioecious. This means that male trees and female trees grow separately.
