G3: Genes, Genomes, Genetics, 2018 The haplodiploid system of sex determination of Hymenoptera acts as an exaptation for species to evolve novel forms of asexual reproduction including thelytoky (clonal offspring of the mother). During normal reproduction in Hymenoptera, three of the four

Facultative use of thelytokous parthenogenesis for queen production in the polyandrous ant
Journal of Evolutionary Biology, 2013 AbstractThe 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. One such species is the ant Cataglyphis cursor, where the queen maximizes the transmission of her genes by producing new queens ...

Psocids from Malta (Insecta: Psocodea: ‘Psocoptera’), with new synonymy for Peripsocus stagnivagus based on the discovery of its first Palaearctic male [PDF]
, 2015 About 2,000 specimens of Psocoptera were collected in Malta recently. Examination of this material revealed 21 new re-cords for the Maltese archipelago, augmenting the known psocid fauna of these islands from 6 to 27 species.

Getting more than a fair share: nutrition of worker larvae related to social parasitism in the Cape honey bee Apis mellifera capensis [PDF]
, 2002 Besides activation of ovaries and thelytokous reproduction of Cape workers, larval nutrition is an important aspect in parasitism of the African honey bee.

Gradual, temperature-induced change of secondary sexual characteristics in Trichogramma pretiosum infected with parthenogenesis-inducing Wolbachia [PDF]
PeerJ, 2019 Intersex is an intermediate stage of sexual differentiation in insects. Determining intersex morphology and the cause of its production will aid in the understanding of the mechanism of sexual differentiation in insects. In this paper, Wolbachia-infected

Worker policing by egg eating in the ponerine ant Pachycondyla inversa [PDF]
, 2004 We investigated worker policing by egg eating in the ponerine ant Pachycondyla inversa, a species with morphologically distinct queens and workers. Colonies were split into one half with the queen and one half without.

Thelytokous parthenogenesis in the damselfly Ischnura hastata (Odonata, Coenagrionidae): genetic mechanisms and lack of bacterial infection [PDF]
Heredity, 2009 Thelytokous parthenogenesis, the production of female-only offspring from unfertilized eggs, has been described in all the insect orders, but is a rare phenomenon in the Odonata (dragonflies and damselflies). The only-known case of parthenogenesis in this group is the North American damselfly species Ischnura hastata, which has parthenogenetic ...

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.

Life-history of the parthenogenetic oonopid spider, Triaeris stenaspis (Araneae: Oonopidae)
European Journal of Entomology, 2009 Selected life-history traits of an oonopid spider, Triaeris stenaspis Simon, which has been introduced into greenhouses in Europe, were investigated. Spiders were reared in the laboratory under constant physical and dietary conditions, and followed from ...
