Wolbachia, sex ratio bias and apparent male killing in the harlequin beetle riding pseudoscorpion

Article Abstract:

The first case of male killing by a tetracycline-sensitive microbe in pseudoscorpions is reported. Using a combination of inheritance studies, antibiotic treatment and molecular essays, it is shown that a new strain of Wolbachia is associated with extreme female bias in the pseudoscorpion, Cordylochernes scorpioides.

Evidence for a new feminizing Wolbachia strain in the isopod Armadilidium vulgare: evolutionary implications

Article Abstract:

Wolbachia are intracellular maternally inherited alpha-Proteobacteria infecting a wide range of arthropods. Comparison of bacterial strains and their respective host mitochondrial phylogenies failed to show concordance, indicating horizontal transmission of the Wolbachia strain within populations of A. vulgare.

Wolbachia variant that induces two distinct reproductive phenotypes in different hosts

Article Abstract:

Wolbachia is an intracellular endosymbiont that induces a variety of reproductive alterations in diverse arthropods. Comparison of the single-and double-infected insects by real-time quantitative polymerase chain reaction suggested that the wCauA density is not affected much by presence or absence of wCauB.
