The kin selection theory of genomic imprinting and modes of reproduction in the eusocial Hymenoptera
Biological Reviews, Volume 98, Issue 2, Page 677-695, April 2023., 2023 ABSTRACT Genomic imprinting is known from flowering plants and mammals but has not been confirmed for the Hymenoptera even though the eusocial Hymenoptera are prime candidates for this peculiar form of gene expression. Here, the kin selection theory of genomic imprinting is reviewed and applied to the eusocial Hymenoptera.

Molecular Ecology, Volume 32, Issue 5, Page 1020-1033, March 2023., 2023 Abstract Clonal reproduction can provide an advantage for invasive species to establish as it can circumvent inbreeding depression which often plagues introduced populations. The world's most widespread invasive ant, Paratrechina longicornis, was previously found to display a double‐clonal reproduction system, whereby both males and queens are produced

Thelytoky and Sex Determination in the Hymenoptera: Mutual Constraints [PDF]
Sexual Development, 2013 The Hymenoptera show a high propensity for transitions from arrhenotokous reproduction (diploid females develop from fertilized eggs, haploid males from unfertilized eggs) to thelytokous reproduction (diploid females develop from unfertilized eggs). However, the evolution of thelytoky is frequently constrained by the sex determination system. Under the

Peer Community Journal, 2022 Hymenopterans are haplodiploids and unlike most other Arthropods they do not possess sexual chromosomes. Sex determination typically happens via the ploidy of individuals: haploids become males and diploids become females.

European Journal of Entomology, 2013 Endosymbiotic organisms are known to manipulate the reproductive biology of their hosts. Incomplete prevalence of endosymbiont inducing thelytokous parthenogenesis results in the coexistence of sexual and asexual individuals, and could account for the ...

Limited Mating Ability of a Wasp Strain with Rickettsia-Induced Thelytoky
Annals of the Entomological Society of America, 2020 Abstract Sexual reproduction is the dominant mode of reproduction in plants and animals; however, some species from various taxonomic groups reproduce asexually. Because some of these asexual species lack DNA recombination and so have low genetic variability, these asexual species are more likely to go extinct than sexual species ...

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.

Restricted Gene Flow among Lineages of Thrips tabaci Supports Genetic Divergence Among Cryptic Species Groups. [PDF]
PLoS ONE, 2016 Knowledge of the relative influence of population- versus species-level genetic variation is important to understand patterns of phenotypic variation and ecological relationships that exist among and within morphologically indistinguishable cryptic ...

Detection of Gene Flow from Sexual to Asexual Lineages in Thrips tabaci (Thysanoptera: Thripidae). [PDF]
PLoS ONE, 2015 Populations of Thrips tabaci are known to have two sympatric but genetically isolated reproductive modes, arrhenotoky (sexual reproduction) and thelytoky (asexual reproduction).
