Association of a new Wolbachia strain with, and its effects on, Leptopilina victoriae, a virulent wasp parasitic to Drosophila spp

Abstract

Wolbachia bacteria are ubiquitous intracellular bacteria of arthropods. Often considered reproductive parasites, they can benefit certain host species. We describe a new Wolbachia strain from Leptopilina victoriae, a Drosophila wasp. The strain is closely related to Wolbachia from Culex sp. Located to the posterior poles of oocytes, it manipulates its host's reproduction by inducing a male development type of cytoplasmic incompatibility. We also report its diverse effects on the wasp's life history traits.
