The results indicate that, although not as prevalent as Wolbachia, the CLO infects a significant number of arthropod hosts (ca. 7.2%) and Sequencing analysis of the 16S rDNA region of theCLO indicates evidence for horizontal transmission of the ClO strains.
Wolbachia pipientis: microbial manipulator of arthropod reproduction.

The alpha-proteobacterium Wolbachia pipientis is a very common cytoplasmic symbiont of insects, crustaceans, mites, and filarial nematodes that has evolved a large scale of host manipulations: parthenogenesis induction, feminization, and male killing.

ABSTRACT A new huanglongbing (HLB) “Candidatus Liberibacter” species is genetically characterized, and the bacterium is designated “Candidatus Liberibacter psyllaurous.” This bacterium infects the…
Antibiotics cause parthenogenetic Trichogramma (Hymenoptera/Trichogrammatidae) to revert to sex.

Completely parthenogenetic Trichogramma wasps can be rendered permanently bisexual by treatment with three different antibiotics or high temperatures. The evidence strongly suggests that maternally…

The aim of this study was to determine the plant host range of the beetle-fungus complex in two heavily infested botanical gardens in Los Angeles County, and revealed 19 tree species that function as reproductive hosts for PSHB.
The utility of internally transcribed spacer 2 DNA sequences of the nuclear ribosomal gene for distinguishing sibling species of Trichogramma

The usefulness of the internally transcribed spacer 2 (ITS2) of the nuclear ribosomal gene complex is tested for providing taxonomic characters to identify Trichogramma species. The ITS2 sequences of…
Cytogenetics of microbe-associated parthenogenesis and its consequences for gene flow in Trichogramma wasps
- R. Stouthamer, D. Kazmer
- BiologyHeredity
- 1 September 1994
The chromosome behaviour in newly laid eggs indicated that the mechanism allowing restoration of diploidy in unfertilized thelytokous eggs was a segregation failure of the two sets of chromosomes in the first mitotic anaphase, which results in a nucleus containing two set of identical chromosomes.
A Multigene Phylogenetic Study of Clonal Diversity and Divergence in North American Strains of the Plant Pathogen Xylella fastidiosa
- E. Schuenzel, M. Scally, R. Stouthamer, L. Nunney
- BiologyApplied and Environmental Microbiology
- 1 July 2005
Two well-differentiated clades probably originated more than 15,000 years ago, long before the introduction of the nonnative plants that characterize most infections, and suggest that, historically, X. fastidiosa has been a clonal organism.
Molecular identification of microorganisms associated with parthenogenesis

- BiologyNature
- 7 January 1993
It is concluded that parthenogenesis bacteria and cytoplasmic incompatibility bacteria form a monophyletic group of microorganisms that 'specialize' in manipulating chromosome behaviour and reproduction of insects.
