A terrifying new strain of red-eyed mutant have been created by scientists.
The wasps were developed in a lab to prove that gene-slicing technology can be used successfully on the tiny parasitic jewel wasps.
Scientists say it has given them a new way to study some of the wasp’s unusual biology.
For instance, it could reveal how males can convert all their progeny into males by using selfish genetic elements.
No one knows how that selfish genetic element in some male wasps ‘can somehow kill the female embryos and create only males,’ said Omar Akbari, an assistant professor of entomology who led the research team at the University of California.
Dr Akbari added: ‘To understand that, we need to pursue their PSR – paternal sex ratio – chromosomes, perhaps by mutating regions of the PSR chromosome to determine which genes are essential for its functionality.’
To do this, scientists used CRISPR technology.
