Researchers have used gene manipulation to create an amazing new mutant wasp with horrifying blood red eyes! A team of scientists at University of California Riverside used CRISPR gene-slicing technology (which sounds more like a salad technology than something used for wasps) in order to permanently alter the eyes of the tiny parasitic jewel wasps (Nasonia vitripennis). Researchers injected DNA and RNA into the nearly microscopic wasp eggs with infinitesimal needles. The resulting red eyes are hereditary and can be passed through successive generations.

The scientists hope to understand how male jewel wasps can somehow ensure that all of their offspring are male—a very unusual ability which geneticists and entomologists would like to understand. However, beyond novelty eye color and sex selection in tiny obscure parasitoid wasps, the researchers are also after bigger game—understanding how to manipulate the genes of all sorts of insects including agricultural pests and dangerous disease-carrying bugs like mosquitos and tsetse flies.
