Thelytoky in Cape honeybees (Apis mellifera capensis) is controlled by a single recessive locus [PDF]
Apidologie, 2017 Worker reproduction in Apis mellifera typically leads to haploid males produced via arrhenotokous parthenogenesis. An exception are laying workers of the South African Cape honeybee Apis mellifera capensis. Due to an abnormal spindle rotation during meiosis A. m. capensis workers are able to produce female progeny via thelytokous parthenogenesis.

Screening for thelytoky in the parahaploid phytoseiid,Metaseiulus occidentalis (Nesbitt)
Experimental & Applied Acarology, 1986M. occidentalis is parahaploid, with unmated females unable to deposit eggs. We screened virgin females from 59 laboratory and field-collected colonies to determine whether thelytoky might occur. The results were negative, among 13 100 females reared in isolation.

Abstract Wolbachia are endosymbiotic bacteria responsible for thelytoky in several parasitoid hymenopteran genera. After finding these micro‐organisms in some populations of Diplolepis spinosissimae (Hymenoptera: Cynipidae) where they are responsible for ...

Evolution of reproductive traits in Cataglyphis desert ants: mating frequency, queen number, and thelytoky [PDF]
Behavioral Ecology and Sociobiology, 2016 Cataglyphis desert ants display unique variation in their breeding systems, making this genus a particularly interesting model to study the evolution of derived reproductive traits in eusocial Hymenoptera. Colonies may be headed by a single or several queens, and queens may be singly or multiply mated.

OBLIGATE THELYTOKY IN ORIBATID MITES: NO EVIDENCE FORWOLBACHIAINDUCEMENT
The Canadian Entomologist, 1997AbstractThe wide distribution of obligate thelytoky in oribatid mites (Acari: Oribatida) raises the question of the mechanisms that allowed genetic diversity to be maintained or even promoted in these taxa. We tested whether or not endosymbiotic bacteriaWolbachiaare associated with thelytoky in eight species of oribatid mites (as it is for most ...

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 Hymenoptera with Venturia canescens and Leptopilina clavipes as Case Studies
2009The insect order of Hymenoptera comprises around 200.000 described species of ants, bees, wasps and sawflies, many of which serve important ecological and economic functions. All Hymenoptera have a haplodiploid mode of reproduction. Males always develop from unfertilized eggs and are haploid.

Biological Cycle of Lorryia formosa (Acari, Tydeidae) on Rubber Tree Leaves: A Case of Thelytoky
Experimental and Applied Acarology, 2006Lorryia formosa Cooreman has been collected on many different host plants around the world. The biological cycle of this species was studied at 28 degrees C with mites collected from a rubber tree crop. The life table was constructed based on sixty individuals. The average lifetime was 37.43 +/- 20.23 (SE) days, and the r(m) was 0.08. The sex ratio was
