Maternally transmitted bacteria of the genus Wolbachia are obligate, intracellular symbionts that are responsible for cytoplasmic incompatibility in a wide range of arthropods such as insects and mites. Spider mites often show uni- and bidirectional incompatibilities among populations with and without Wolbachia. Therefore, we surveyed the presence of Wolbachia by PCR and then conducted crossing experiments among 25 populations of Panonychus mori to determine how Wolbachia are related to the incompatibility in this species. Five out of the 25 populations were infected with Wolbachia. These five populations were treated with an antibiotic (rifampicin) to eliminate Wolbachia. We carried out round-robin crosses among 20 Wolbachia-uninfected populations, five infected populations and five rifampicin-treated populations (30 x 30=900 crosses in total). Incompatibility among P. mori populations was caused by Wolbachia infection, nuclear-cytoplasmic interactions or nuclear-nuclear interactions. Wolbachia-mediated incompatibility was observed in crosses between uninfected females and infected males or between females and males harboring different Wolbachia strains. Nuclear-cytoplasmic interactions may be responsible for the unidirectional incompatibility in crosses between the two northern populations and one of the southern populations. Bidirectional incompatibility caused by nuclear-nuclear interactions was observed in 99 combinations of interpopulation crosses (99/300=0.33). Although no geographical trends were detected in the distribution of bidirectionally compatible populations, the results reveal a genetic divergence among P. mori populations.
