Asexual lineages can derive from sexual ancestors via different mechanisms and at variable rates, which affects the diversity of the asexual population and thereby its ecological success. [] Key Result Extensive population surveys and breeding experiments indicated sexual reproduction in A. elegans, asexuality in A. stylifer and A. karnyi, and both sexual and asexual lineages in A. rufus.

Sexual versus Asexual Reproduction: Distinct Outcomes in Relative Abundance of Parthenogenetic Mealybugs following Recent Colonization

A sympatric occurrence of sexual and asexual reproduction in the pineapple mealybug, Dysmicoccus brevipes, offers a unique opportunity to assess the relative success of sexual versus asexual lineages with an unusual morphology and life cycle.

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.

Comparative screening of endosymbiotic bacteria associated with the asexual and sexual lineages of the termite Glyptotermes nakajimai

Bacterial screening of the asexual lineage of the termite Glyptotermes nakajimai did not reveal any likely causal agents for parthenogenetic reproduction, whereas screened of the sexual lineage resulted in Wolbachia being detected, suggesting that the a sexuality in G. nakjimai is likely to be maintained without manipulation by endosymbiotic bacteria.

Adaptations to different habitats in sexual and asexual populations of parasitoid wasps: a meta-analysis

Each form has consistent multiple adaptations to the ecological circumstances in the contrasting environments and it is found that sexuals invest more in longevity at the expense of egg-load, are more mobile, and display higher plasticity in response to thermal variability than asexual counterparts.

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.

Extreme genetic diversity in asexual grass thrips populations

Evaluated patterns of intra‐ and interpopulation genetic diversity in sexual and asexual populations of Aptinothrips rufus grass thrips found that asexual A. rufUS populations are characterized by extremely high levels of genetic diversity, both in comparison with their sexual relatives and in compared with other asexual species.

Evolution and comparative ecology of parthenogenesis in haplodiploid arthropods

The results strongly suggests that transitions to parthenogenesis are more frequent in large sexual populations and/or that the risk of extinction of parthenogens with large population sizes is reduced.

Marginal distribution and high heterozygosity of asexual Caloglossa vieillardii (Delesseriaceae, Rhodophyta) along the Australian coasts

It is hypothesized that the most abundant heterozygous genotype (defined as type 3/4) in asexual populations occurred by a cross between type 3 and type 4 allele gametophytes, both of which were isolated from the Australian coasts.

Bacteriome‐associated Wolbachia of the parthenogenetic termite Cavitermes tuberosus

A unique strain of Wolbachia nested in the supergroup F, nested in 28 nests collected in French Guiana, the island of Trinidad and the state of Paraíba, Brazil, is found, which infects individuals regardless of caste, sex or reproductive (sexual versus parthenogenetic) origin.

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.



Origins of asexuality in Bryobia mites (Acari: Tetranychidae)

It is argued that asexuality originated multiple times within the genus Bryobia, signifying that some animal taxa do contain a high number of asexuals.

The genetics of obligate parthenogenesis in an aphid species and its consequences for the maintenance of alternative reproductive modes

The genetic basis of OP in the cereal aphid Sitobion avenae is explored by crossing several genotypes with contrasting reproductive modes and then characterising the reproductive phenotypes of F1 and F2 offspring, which suggests that at least two autosomal loci control OP in S. avenae.

Asexuality cured: the relations and differences between sexual and asexual Apoanagyrus diversicornis

A sexual A. diversicornis strain was introduced into Africa for the biological control of the cassava mealybug Phenacoccus manihoti and was intermediate between the survival probabilities of the parental strains.

Independently Evolving Species in Asexual Bdelloid Rotifers

It is shown that a classic asexual clade, the bdelloid rotifers, has diversified into distinct evolutionary species and demonstrates how combined molecular and morphological analyses can shed new light on the evolutionary nature of species.

A new case of Wolbachia dependence in the genus Asobara: evidence for parthenogenesis induction in Asobara japonica

It is shown that while males were still sexually functional, females no longer attract males, making Wolbachia an obligate partner for daughter production in thelytokous populations, and the stability of these obligatory associations is questioned.

Loss of Sexual Reproduction and Dwarfing in a Small Metazoan

Transitions to obligate parthenogenesis (OP) in the rotifer Brachionus calyciflorus, a small freshwater invertebrate, were controlled by a simple Mendelian inheritance and found no adverse effects of OP on survival or fecundity.

First Detection of Wolbachia in Arrhenotokous Populations of Thrips Species (Thysanoptera: Thripidae and Phlaeothripidae) and Its Role in Reproduction

Wolbachia was found in the thelytokous reproducing species H. femoralis and P. dracaenae and proved the presence of the bacterium for the first time in some arrhenotokous reproducecing thrips species.

Cardinium symbionts induce haploid thelytoky in most clones of three closely related Brevipalpus species

The mode of thelytokous reproduction in Brevipalpus phoenicis, B. obovatus and B. californicus is investigated, showing that males can be produced by very young females only, while older females produce daughters exclusively, and taxonomic revision of this group is necessary.

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.
