Revealing parthenogenetic reproduction in a praying mantis inhabiting South American grasslands [PDF]

open access: yesScientific Reports
Mantids are charismatic insects due to their appearance and behaviors, but knowledge about them, in particular at the Neotropics, is scarce. Brunneria subaptera (Coptopterygidae) is the most abundant praying mantis species in Uruguay, inhabiting one of ...

Decay of homologous chromosome pairs and discovery of males in the thelytokous fungus-growing ant Mycocepurus smithii [PDF]

open access: yesScientific Reports, 2022
The prevalent mode of reproduction among ants is arrhenotokous parthenogenesis where unfertilized eggs give rise to haploid males and fertilized eggs develop into diploid females.

Parthenogenesis in scorpions: some history - new data [PDF]

open access: yesJournal of Venomous Animals and Toxins including Tropical Diseases, 2008
Parthenogenesis, a rare phenomenon in Chelicerates, apart from mites, is reviewed in scorpions, notably Tityus serrulatus Lutz & Mello from Brazil, Tityus columbianus (Thorell) from Colombia and Tityus metuendus Pocock from Peru and Brazil.

Oviposition Traits and Vitellogenin-Related Gene Functions in Ooencyrtus kuvanae [PDF]

open access: yesInsects
Ooencyrtus kuvanae is an egg parasitoid species that attacks the egg masses of Dendrolimus spp. and Lymantria spp. in China, which gives it a temporal niche advantage against pest infestations by Dendrolimus spp. and Lymantria spp.

A method for estimating variation in the phenotypic expression of morphological characters by thelytokous parthenogenesis in Apis mellifera capensis [PDF]

open access: yesApidologie, 2002
Les ouvrieres pondeuses de l'abeille du Cap (Apis mellifera capensis Escholtz) produisent une descendance femelle par parthenogenese thelytoque, ce qui permet de quantifier les effets de l'environnement sur l'expression du genotype dans les lignees clonales.

Curing Parthenogenesis-Inducing (PI) Wolbachia-Induced Reproductive Disorders in the Egg Parasitoid Telenomus remus [PDF]

open access: yesBiology
Wolbachia is an endosymbiotic bacterium widespread in invertebrates that causes various reproductive effects, including cytoplasmic incompatibility, feminization, male killing, and the induction of parthenogenesis (PI).

Cytological mechanisms of thelytokous parthenogenesis in insects

open access: yesGenome, 1987
The eight female parthenogenetic mechanisms recognized in insects are organized under the broad categories "ploidy restoration" and "ploidy stasis." Each term replaces three imprecise and inappropriate existing names. Of the eight mechanisms, two are given names for the first time, and a table brings together all mechanisms in a new manner that shows ...

Effects of Thelytokous Parthenogenesis-Inducing Wolbachia on the Fitness of Trichogramma dendrolimi Matsumura (Hymenoptera: Trichogrammatidae) in Superparasitised and Single-Parasitised Hosts [PDF]

open access: yesFrontiers in Ecology and Evolution, 2021
Thelytokous Wolbachia-infected Trichogramma species have long been considered as biological control agents against lepidopteran pests in agriculture and forestry.

The first gynandromorph of a zorapteran and potential thelytokous parthenogenesis in a population of Zorotypus brasiliensis Silvestri (Zoraptera: Zorotypidae)

open access: yesRevista Brasileira de Entomologia, 2017
The first gynandromorph of the insect order Zoraptera is reported. A gynandromorph of Zorotypus brasiliensis Silvestri is described from a likely parthenogenetic population in the Atlantic Forest around the border of the Brazilian states of Minas Gerais, Rio de Janeiro, and São Paulo.

Genetic evidence for parthenogenesis in the small carpenter bee Ceratina dallatoreana (Apidae, Ceratinini) in its native distribution range [PDF]

open access: yesJournal of Hymenoptera Research, 2023
Arrhenotoky is the typical mode of reproduction in Hymenoptera. Diploid females develop from fertilized eggs, whereas haploid males originate from unfertilized eggs.
