| Research Abstract |
Wolbachia are endosymbiotic bacteria in arthropods including insects, and capable of manipulating host reproduction by causing cytoplasmic incompartibility, parthenogenesis, male killing or feminization. In this study, effect of artificial injection of the Wolbachia of Collosobruchus chinensis (cause cytoplasmic incompartibility to the host) to Monochamus alternatus was investigated. Mating experiments between Wolbachia-injected individuals and non-injected individuals revealed that only the hatching rate of eggs produced by mating of injected males x non-injected females decreased remarkably. This means that the Wolbachia of C. chinensis caused cytoplasmic incompartibility to M. alternatus.
