Thelytoky in the honey bee [PDF]
Apidologie, 2014 Thelytoky, the asexual production of females, is rare in honey bees. However, it is ubiquitous in workers of the Cape honey bee Apis mellifera capensis. Thelytoky allows some workers to be reincarnated into the queen phenotype, and thereby selects for reproductive competition among workers.

Cytogenetic basis of thelytoky in Apis mellifera capensis [PDF]
Apidologie, 2017 Haplodiploid insects reproduce both sexually and asexually; haploid males arise from unfertilized eggs, while diploid females arise from fertilized eggs. Some species can also produce female offspring by thelytokous parthenogenesis. For example, queenless workers of the Cape honey bee, Apis mellifera capensis, of South Africa can produce diploid female

Inheritance of thelytoky in the honey bee Apis mellifera capensis [PDF]
Heredity, 2015 Asexual reproduction via thelytokous parthenogenesis is widespread in the Hymenoptera, but its genetic underpinnings have been described only twice. In the wasp Lysiphlebus fabarum and the Cape honey bee Apis mellifera capensis the origin of thelytoky have each been traced to a single recessive locus.

Cytogenetic mechanism and genetic consequences of thelytoky in the wasp Trichogramma cacoeciae [PDF]
Heredity, 2004 In Hymenoptera, complete parthenogenesis, that is thelytoky, is a common phenomenon where virgin females produce only daughters. Thelytoky is often induced by bacteria of the genus Wolbachia, but can also be genetically determined by the insect itself, as in the genus Trichogramma where both forms exist. In order to compare these two forms of thelytoky,

The distribution of thelytoky, arrhenotoky and androgenesis among castes in the eusocial Hymenoptera
Insectes Sociaux, 2017Thelytokous parthenogenesis is the production of females from unfertilized eggs. In this review we categorize the known thelytokous eusocial Hymenopterans (mostly ants) by their modes of worker and queen reproduction. The resultant tabulation reveals that: (1) there are no species in which queens are thelytokous and workers are exclusively ...

Gonoid thelytoky in soft scale insects (Coccidae: Homoptera)
Chromosoma, 1979Cytological analysis of the thelytokous soft-scale insects Coccus hesperidum L. (2n=14) and Saissetia coffeae (Walker) (2n=16) revealed that while in both “species” the chromosomes did not pair during prophase I, meiosis consisted of two divisions, the chromosome number was reduced, and diploidy was restored by the fusion of the female pronucleus with ...

The cytogenetics of thelytoky in a predominantly asexual parasitoid wasp with covert sex
Genome, 2003Asexual lineages in the parasitoid wasp Lysiphlebus fabarum (Hymenoptera: Braconidae: Aphidiinae) have previously been shown to have occasionally undergone sexual reproduction and recombination with males from related sexual populations. In the present study, the cytogenetic system of asexual females in this species is shown by 4',6-diamidino-2 ...
