Analysis of caste diversification and the origin of thelytoky in North American honey bees, Apis mellifera (Hymenoptera: Apidae): a morphological perspective

open access: yes, 2002
Thelytoky is a subset of parthenogenetic processes in which a female produces unfertilized eggs that develop into an all-female lineage. Thelytoky frequently occurs in the African Cape honey bee.

Data from: Facultative use of thelytokous parthenogenesis for queen production in the polyandrous ant Cataglyphis cursor

open access: yes, 2013
The evolutionary paradox of sex remains one of the major debates in evolutionary biology. The study of species capable of both sexual and asexual reproduction can elucidate factors important in the evolution of sex.

Phylogeny and host-symbiont interactions of thelytoky inducing Wolbachia in Hymenoptera

open access: yes
Summary and conclusionsBacteria of the genus Wolbachia (α-Proteobacteria, Rickettsia) are widespread in arthropods and can induce thelytoky (T) in parasitoids (Hymenoptera). Infection with thelytoky inducing Wolbachia (T- Wolbachia ) enables infected females to produce daughters from unfertilised eggs.

Systematic and Evolutionary Implications of Parthenogenesis in the Hymenoptera

open access: yes, 1971
Two types of parthenogenesis, arrhenotoky and thelytoky, exist in the Hymenoptera. Arrhenotoky, the development of males from unfertilized eggs, is present in all wasps and bees.

When and where to have sex? Different modes of reproduction and life history traits in the facultative parthenogenetic ant Platythyrea punctata [PDF]

open access: yes, 2010
Hymenopterans generally exhibit a haplo-diploid sex determination mechanism, in which females are produced by sexual reproduction and are diploid and males are produced parthenogenetically and are haploid.
