Vertically transmitted bacteria of the genus Wolbachia are obligatory endosymbionts known to cause thelytokous (asexual) reproduction in many species of parasitic Hymenoptera. In these species production of males can be induced, but attempts to establish sexual lines have failed in all but one genus. We have found three reproductive barriers between antibiotic‐induced males and conspecific females of Muscidifurax uniraptor Kogan and Legner (Hymenoptera: Pteromalidae): males do not produce… 

Sexual functionality of Leptopilina clavipes (Hymenoptera: Figitidae) after reversing Wolbachia‐induced parthenogenesis

The results indicate that although males show a decay of sexual function, they are still able to fertilize uninfected females and the absence of genomic incompatibilities suggests that these effects are due to the difference in mode of reproduction.

The genetics and evolution of obligate reproductive parasitism in Trichogramma pretiosum infected with parthenogenesis-inducing Wolbachia

Through a series of backcrossing experiments with an uninfected Trichogramma pretiosum population, the genetic basis for the loss of female sexual function could be explained by a dominant nuclear effect and the dynamics of sex ratio selection in PI Wolbachia-infected populations are discussed.

Microorganisms and parthenogenesis

Endosymbionts are being discovered in unprecedented numbers of invertebrate species, and recent studies indicate that Wolbachia might be just one of a rapidly increasing list of intracellular bacteria capable of inducing parthenogenesis in their host.

Reduced sexual functionality of PI‐Wolbachia‐infected females of Tetrastichus coeruleus

Mated females had shorter life spans than virgin females, showing that mating carried a fitness cost, and accumulation of neutral mutations, functional virginity mutations, manipulation by Wolbachia, and/or the genetic distance between the two populations may all have contributed to the decay of sexual traits in thelytokous females.

The Wolbachia Endosymbionts.

The Wolbachia endosymbionts encompass a large group of intracellular bacteria of biomedical and veterinary relevance, closely related to Anaplasma, Ehrlichia, and Rickettsia, which are essential to the survival and reproduction of their filarial nematode hosts and an attractive target to fight filariasis.

Limited Mating Ability of a Wasp Strain with Rickettsia-Induced Thelytoky

It is confirmed that the thelytokous strain has been maintained by a functional apomixis mechanism rather than by occasional sex, preserving a degree of heterozygosity.

Evidence for an one-step mechanism of endosymbiont-induced thelytoky in the parasitoid wasp, Muscidifurax uniraptor

Wolbachia only needs to induce diploidization and that bi-allelic Mutra expression is sufficient for female development in sexually reproducing sister species, Muscidifurax raptorellus, and artificially created triploid females to determine whether diploidsization is necessary for feminization.

Genetics of female functional virginity in the Parthenogenesis-Wolbachia infected parasitoid wasp Telenomus nawai (Hymenoptera: Scelionidae)

The genetic basis of the females' inability to reproduce sexually is determined by introgressing the genome of a thelytokous line into an arrhenotokous Line by suggesting that the mutations are recessive and inherited either as a single-locus major gene with some modifiers, or as two partially linked loci.

Patterns and mechanisms in instances of endosymbiont‐induced parthenogenesis

The literature survey indicates that endosymbiont‐induced parthenogenesis is known or suspected in 124 host species from seven different arthropod taxa and suggests specific approaches that allow for firm conclusions about the involvement of endosYmbionts in the origin of parthenogenic.

Intragenomic conflict in populations infected by Parthenogenesis Inducing Wolbachia ends with irreversible loss of sexual reproduction

This study shows that dependence among organisms can evolve rapidly due to the resolution of the conflicts between cytoplasmic and nuclear genes, and without requiring a mutualism between the partners.

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.

Experiments show that bacterial density is correlated with compatibility differences between male and female Nasonia, and this result is consistent with a critical "imprinting" period during egg maturation, when cytoplasmic bacteria determine compatibility.

Observations reinforce the notion that Wolbachia may be an important agent driving arthropod evolution, and corroborates previous suggestions that male–killing behaviour is easily evolved by invertebrate symbionts.

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.
