Facultative parthenogenesis in the burrowing mayfly, Ephoron eophilum (Ephemeroptera: Polymitarcyidae) with an extremely short alate stage

European Journal of Entomology, 2015
Facultative parthenogenesis is important for mayflies with short alate stages because females are able to reproduce without mating. We studied facultative parthenogenesis in Ephoron eophilum, a mayfly with an extremely short alate stage.

The complete mitochondrial genome of a parthenogenetic ant Monomorium triviale (Hymenoptera: Formicidae)

Mitochondrial DNA. Part B. Resources, 2021
Monomorium is one of the most species-rich yet taxonomically problematic ant genus. An East Asian species, M. triviale Wheeler, W.M., 1906, is reproduced by obligate thelytokous parthenogenesis and performs strict reproductive division of labor.

Exploring the relationship between tychoparthenogenesis and inbreeding depression in the Desert Locust, Schistocerca gregaria [PDF]

, 2017
Tychoparthenogenesis, a form of asexual reproduction in which a small proportion of unfertilized eggs can hatch spontaneously, could be an intermediate evolutionary link in the transition from sexual to parthenogenetic reproduction.

A single locus determines thelytokous parthenogenesis of laying honeybee workers (Apis mellifera capensis) [PDF]

Heredity, 2005
The evolution and maintenance of parthenogenetic species are a puzzling issue in evolutionary biology. Although the genetic mechanisms that act to restore diploidy are well studied, the underlying genes that cause the switch from sexual reproduction to parthenogenesis have not been analysed. There are several species that are polymorphic for sexual and

Widespread occurrence of asexual reproduction in higher termites of the Termes group (Termitidae: Termitinae)

BMC Evolutionary Biology, 2019
Background A decade ago, the mixed reproductive strategy Asexual Queen Succession (AQS) was first described in termites. In AQS species, the workers, soldiers and dispersing reproductives are produced through sexual reproduction, while non-dispersing ...

Parthenogenesis in scorpions: some history - new data

Journal 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.

A Single Gene Causes Thelytokous Parthenogenesis, the Defining Feature of the Cape Honeybee Apis mellifera capensis [PDF]

Current Biology, 2020
In honeybees, the ability of workers to produce daughters asexually, i.e., thelytokous parthenogenesis, is restricted to a single subspecies inhabiting the Cape region of South Africa, Apis mellifera capensis. Thelytoky has unleashed new selective pressures and the evolution of traits such as social parasitism, invasiveness, and social cancer ...

Microbiome composition is shaped by geography and population structure in the parasitic wasp Asobara japonica, but not in the presence of the endosymbiont Wolbachia

Molecular Ecology, Volume 32, Issue 23, Page 6644-6658, December 2023., 2023
Abstract The microbial community composition is crucial for diverse life‐history traits in many organisms. However, we still lack a sufficient understanding of how the host microbiome is acquired and maintained, a pressing issue in times of global environmental change. Here we investigated to what extent host genotype, environmental conditions, and the

Diploid males support a two-step mechanism of endosymbiont-induced thelytoky in a parasitoid wasp. [PDF]

, 2015
BACKGROUND: Haplodiploidy, where females develop from diploid, fertilized eggs and males from haploid, unfertilized eggs, is abundant in some insect lineages.

The frequency of thelytokous parthenogenesis in European-derived Apis mellifera virgin queens [PDF]

Apidologie, 2019
Thelytokous parthenogenesis is the asexual production of female progeny. In the honey bee, Apis mellifera, thelytoky is unknown from mated queens, but can occur in virgin queens that have been induced to lay. We used microsatellite markers to quantify theltyoky in virgin A.
