Cytogenetic mechanism and genetic consequences of thelytoky in the wasp Trichogramma cacoeciae [PDF]

open access: yesHeredity, 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,

Inheritance of thelytoky in the honey bee Apis mellifera capensis [PDF]

open access: yesHeredity, 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.

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

open access: yesExperimental and Applied Acarology, 2006
Bacterial symbionts that manipulate the reproduction of their host to increase their own transmission are widespread. Most of these bacteria are Wolbachia, but recently a new bacterium, named Cardinium, was discovered that is capable of the same manipulations.

Thelytoky in the honey bee [PDF]

open access: yesApidologie, 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.

Worker thelytoky allows requeening of orphaned colonies but increases susceptibility to reproductive cheating in an ant

open access: yesAnimal Behaviour, 2018
International audienceIn some social insects, workers can produce females asexually through thelytokous parthenogenesis. This allows them to produce replacement queens (i.e. requeening) if the queen has died, but also to compete with the queen to produce

The distribution of thelytoky, arrhenotoky and androgenesis among castes in the eusocial Hymenoptera

Insectes Sociaux, 2017
Thelytokous 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, 1979
Cytological 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 ...
