Abstract: | Background Patterns of mtDNA variation within a species reflect long-term population structure, but may also be influenced by maternally
inherited endosymbionts, such as Wolbachia. These bacteria often alter host reproductive biology and can drive particular mtDNA haplotypes through populations. We investigated
the impacts of Wolbachia infection and geography on mtDNA variation in the diamondback moth, a major global pest whose geographic distribution reflects
both natural processes and transport via human agricultural activities. |
