Like a foreign movie: Parasitic wasps evolve inside hosts

Additionally, male hornet species can identify potential mates for breeding – even before they hatch from spoiled prey. About the latest search results NewScientist Science Journal mentioned.

Small Parasitic Essences (Nasonia vitrippines) They live in North America, and the breeding of this species is both frightening and special.

Females lay eggs in cocoons of developing flies. The wasps then remain in the cocoons and only eat themselves outside of the host’s body during mating.

The males hatch first and then wait for the females to appear near the hosts. Therefore, males must find hosts that hide females for mating to be successful.

The video below shows a wasp escaping from a fly’s egg:

Male wasps hatch from unfertilized eggs and females from fertilized eggs, so in some families only male wasps and in other cases males and females mixed.

Researchers collected gem wasps in nature and then bred them to study this phenomenon. In their experiment, they were shown two petri dishes of male wasps, in one they placed a host containing only males, and in the other a mixture of male and female wasps.

The researchers found that male wasps spent four times the time on a host that also included a female.

To be able to see how wasps were able to determine which host contained a female, the researchers looked at the chemical composition of the pupae. And it found that those that included the female also contained more bicarbonate that made up the body of the female wasp.

Based on the results, males can also sense this difference inside air bubbles. Researchers say that even other species, not necessarily a parasite, may use this fun way to get along.
