Based on sex-ratio analysis, thelytokous parthenogenesis is shown to be widespread in the mite taxon Desmonomata (Nothroidea sensu lato), with four of the seven families completely thelytokous and a fifth nearly so. Monthly samples from populations in central New York State, Japan, and Canada, representing 22 species in five families, indicate that sex-

The frequency of thelytokous parthenogenesis in European-derived Apis mellifera virgin queens [PDF]
Apidologie, 2019 Thelytokous parthenogenesis is the asexual production of female progeny. In the honey bee, Apis mellifera, thelytoky is unknown from mated queens, but can occur in virgin queens that have been induced to lay. We used microsatellite markers to quantify theltyoky in virgin A.

Thelytokous Parthenogenesis in Eusocial Hymenoptera
Annual Review of Entomology, 2013Female parthenogenesis, or thelytoky, is particularly common in solitary Hymenoptera. Only more recently has it become clear that many eusocial species also regularly reproduce thelytokously, and here we provide a comprehensive overview. Especially in ants, thelytoky underlies a variety of idiosyncratic life histories with unique evolutionary and ...

A single locus determines thelytokous parthenogenesis of laying honeybee workers (Apis mellifera capensis) [PDF]
Heredity, 2005 The evolution and maintenance of parthenogenetic species are a puzzling issue in evolutionary biology. Although the genetic mechanisms that act to restore diploidy are well studied, the underlying genes that cause the switch from sexual reproduction to parthenogenesis have not been analysed. There are several species that are polymorphic for sexual and

Lack of meiotic recombination in thelytokous parthenogenesis of laying workers of Apis mellifera capensis (the Cape honeybee) [PDF]
Heredity, 1994 Offspring of thelytokous laying workers of Apis mellifera capensis were screened using multilocus DNA fingerprinting with the (GATA)4 oligonucleotide. All screened offspring workers revealed an identical DNA fingerprint pattern, lacking evidence of any meiotic recombination.

Genetic diversity and the phylogeography of parthenogenesis: comparing bisexual and thelytokous populations of Nemasoma varicorne (Diplopoda: Nemasomatidae) in Denmark [PDF]
Hereditas, 2002 The millipede, Nemasoma varicorne, represents a textbook example of geographic parthenogenesis with thelytokous populations being distributed north, east, south and west of the distribution of the bisexual ancestor in the deciduous forests of central Europe.

THELYTOKOUS PARTHENOGENESIS IN CEPHUS CINCTUS NORT.: A CRITICISM
The Canadian Entomologist, 1938I have read with great interest C. W. Farstad's paper (1938) on “Thelyotokous parthenogenesis in Cephus cinctus Nort.,” since it parallels so closely my own problem in Diprion polytomum Hartig. But, whilst agreeing with his final conclusion that there are doubtless two forms of C. cinctus manifesting alternative modes of parthenogenetic reproduction in

Thelytokous Parthenogenesis in the AntMyrmecina nipponica(Hymenoptera: Formicidae)
Zoological Science, 2014Myrmecina nipponica Wheeler is a terrestrial ant nesting chiefly in the soil in forest. It is a specialized predator of oribatid mites, but also scavenges on a broad spectrum of other arthropods. In the studied population at Cape Manazuru in central Japan, M. nipponica colonies are typically monogynous, and previous dissections of queens suggested that
