Abstract Insects in the order Thysanoptera are known for their haplodiploid reproduction, with most species reproducing by arrhenotoky. A few species, however, have only female populations and reproduce by thelytoky. Seven thrips species reproducing either by arrhenotoky [Frankliniella occidentalis (Pergande), Echinothrips americanus Morgan, Suocerathrips linguis Mound and Marullo, Gynaikothrips ficorum (Marchal)] or thelytoky [Hercinothrips femoralis (O.M. Reuter) and Parthenothrips dracaenae… 

Genetic diversity, reproductive systems and endosymbionts of two invasive thrips species

It is demonstrated that global population samples of H. haemorrhoidalis were not infected with Wolbachia, Cardinium or any other known bacterial reproductive manipulators, and polyploidy may be a contributing factor in the reproduction of Thysanoptera and other haplodiploid insect orders.

Dependence of egg hatching on Wolbachia density in a parthenogenetic weevil revealed by antibiotic treatment

It is hypothesized that a minimum threshold density of Wolbachia is required for weevil reproduction, and it is inferred that WolbachIA most probably takes part in the reproduction of P. postfasciatus reproduction.

Polyploidy versus endosymbionts in obligately thelytokous thrips

It is demonstrated that global population samples of H. haemorrhoidalis were not infected with Wolbachia, Cardinium or any other known bacterial reproductive manipulators, and polyploidy may be a contributing factor in the reproduction of Thysanoptera and other haplodiploid insect orders.

Population structure and genetic diversity analysis in Gynaikothrips uzeli (Zimerman, 1909) (Thysanoptera: Phlaeothripidae) by RAPD markers

The genetic diversity of G. uzeli was reduced, putatively related to the haplodiploid sex determination system, and to ecological traits of the studied species, such as the low dispersal abilities and life mode in leaf galls.

Loss of Wolbachia but not Cardinium in the invasive range of the Australian thrips species, Pezothrips kellyanus

It is highlighted that endosymbionts may be potential factors in the framework of the enemy release hypothesis that predicts success of invasive hosts in the absence of natural enemies.

Natural History of Gynaikothrips uzeli (Thysanoptera: Phlaeothripidae) in Galls of Ficus benjamina (Rosales: Moraceae)

Investigation of aspects of the natural history of Gynaikothrips uzeli Zimmermann, 1900 in galls using seasonal sampling (summer and winter) found that thrips showed greater abundance at higher temperatures and no precipitation, pointing to an inbred mating structure.

Detection and Localization of Wolbachia in Thrips palmi Karny (Thysanoptera: Thripidae)

The presence of Wolbachia supergroup B strain for the first time in T. palmi was confirmed by PCR using genus specific primers of 16S rRNA gene and a phylogenetic tree was constructed with concatenated sequences of ftsZ and gatB gene to assign supergroup to WolbachIA.


Investigation of the variation and evolution of reproductive systems in Aptinothrips, a genus of grass thrips comprising four species, reveals different causes of asexuality in different species, opening new perspectives for studies on the maintenance of mixed sexual and asexual reproduction in natural populations.

Survey of Wolbachia frequency in Nashville, Tennessee Reveals Novel Infections

These results expand on the field's understanding of Wolbachia’s frequency in Nashville, Tennessee, and among arthropod families broadly, and is the first report of Wolachia in centipedes.

First insight into microbiome profile of fungivorous thrips Hoplothrips carpathicus (Insecta: Thysanoptera) at different developmental stages: molecular evidence of Wolbachia endosymbiosis

Characterization of bacterial communities of four developmental stages of the fungivorous species Hoplothrips carpathicus, verification of the presence of Wolbachia, in silico prediction of metabolic potentials of the microorganisms, and sequencing its mitochondrial COI barcode showed that changes in microbiome composition are congruent with the successive stages of H. car pathicus development.



Parthenogenesis‐inducing microorganisms in Aphytis (Hymenoptera: Aphelinidae)

Production of males in uniparental lines of two species in the parasitic wasp genus Aphytis was induced by rifampicin, and male sexual functioning was determined, and sperm failure to effect egg fertilization resulted in all‐male progeny.

Taxonomic Status of Thelytokous Forms of Trichogramma (Hymenoptera: Trichogrammatidae)

The discovery that antibiotics and high temperatures can permanently change the mode of reproduction of the majority of thelytokous forms of Trichogramma to arrhenotoky now makes it possible to use male anatomy and reproductive compatibility as criteria for species identity.

Reproductive Modes in Onion Thrips (Thysanoptera: Thripidae) Populations from New York Onion Fields

Investigation of patterns of reproductive modes in onion thrips, Thrips tabaci Lindeman, populations and potential effects of the bacterium Wolbachia and temperature on these modes found male-producing T. tabaci populations were not positively correlated with resistance to lambda-cyhalothrin, or tolerance to methomyl.

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.

Through antibiotic treatment, it is shown that, in two species, Bryobia praetiosa and an unidentified species, the Wolbachia infection is strictly associated with parthenogenesis, and microsatellite loci show the mechanism of parthenogenic to be functionally apomictic and not gamete duplication, with progeny identical to their infected mother.

Male–killing Wolbachia in two species of insect

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.

How many species are infected with Wolbachia? Cryptic sex ratio distorters revealed to be common by intensive sampling

It is concluded that sex–ratio–distorting Wolbachia may be common in insects that have an ecology and/or genetics that permit the invasion of these parasites and that previous surveys may have seriously underestimated the proportion of species that are infected.

Wolbachia endosymbionts responsible for various alterations of sexuality in arthropods

Three molecular lineages can be identified on the basis of 16S as well as 23S sequences, and Wolbachia spread by horizontal transfer across host lineages as evidenced by their diversification which occurred long after that of their hosts, and by the non-congruence of the phylogenetic relationships of symbionts and their hosts.

Removing symbiotic Wolbachia bacteria specifically inhibits oogenesis in a parasitic wasp

It is concluded that Wolbachia is necessary for oogenesis in these A. tabida strains, and this association would seem to be the first example of a transition from facultative to obligatory symbiosis in arthropod–Wolbachia associations.

Wolbachia–mediated parthenogenesis in the predatory thrips Franklinothrips vespiformis (Thysanoptera: Insecta)

A parthenogenetic colony of a predatory thrips Franklinothrips vespiformis (Aeolothripidae) possessed B-group Wolbachia, which caused thelytoky, which is a form of parthenogenesis in which females produce females without males in hymenopteran insects.
