title: Wolbachia pipientis is associated with different mitochondrial haplotypes in natural populations of Drosophila willistoni.
abstract: The prevalence of the endosymbiont Wolbachia pipientis and its effects on mitochondrial genetic diversity were analyzed in natural populations of Drosophila willistoni, a neotropical species recently infected. Total infection rate was 55% and no evidence was found that the Wolbachia infection decreased the diversity of mtDNA. Wolbachia was seen to be associated with different mitochondria, suggesting multiple horizontal transmission events and/or transmission paternal leakage of mitochondrial and/or Wolbachia. These hypotheses are evaluated in the context of the present study and other research.
