Nasonia is a genus of small parasitoid wasps used in research on genetics, speciation and host interactions. Developing offspring exploit a host animal rather than merely sharing its environment. Nasonia vitripennis and Nasonia giraulti support comparisons between related species.

Nasonia giraulti is a parasitoid wasp studied in comparison with Nasonia vitripennis. Crosses and behavioral measurements can separate inherited differences from environmental influences and help investigate barriers between species.
