Apomixis for no bacteria-induced thelytoky in Diglyphus wani (Hymenoptera: Eulophidae) [PDF]
Frontiers in Genetics, 2023 In Hymenoptera species, the reproductive mode is usually arrhenotoky, where haploid males arise from unfertilized eggs and diploid females from fertilized eggs.

Evaluation of the Parasitism Capacity of a Thelytoky Egg Parasitoid on a Serious Rice Pest, Nilaparvata lugens (Stål) [PDF]
Animals, 2022 Pseudoligosita yasumatsui and Anagrus nilaparvatae are both egg parasitoids of the brown planthopper, Nilaparvata lugens (Stål) (BPH). In this study, we obtained a stable strain of P.

Multiple Data Demonstrate That Bacteria Regulating Reproduction Could Be Not the Cause for the Thelytoky of Diglyphus wani (Hymenoptera: Eulophidae) [PDF]
Insects, 2021 In Hymenoptera parasitoids, the reproductive mode is arrhenotoky, while a few species reproduce by thelytoky. The thelytoky of Hymenoptera parasitoids is generally genetically determined by the parasitoids themselves or induced by bacteria, including ...

Anniversary of a beekeeper’s discovery of thelytoky in Cape honey bees
South African Journal of Science, 2022 The existence of thelytoky in Cape honey bees was first documented in 1912 – making 2022 the 110th anniversary of this discovery. The significance of this discovery took a number of decades to be fully appreciated.

Evolutionary Potential of Parthenogenesis—Bisexual Lineages within Triploid Apomictic Thelytoky in Cacopsylla ledi (Flor, 1861) (Hemiptera, Psylloidea) in Fennoscandia [PDF]
Insects, 2022 A widely accepted hypothesis is that parthenogenesis is an evolutionary dead end since it is selectively advantageous in the short term only but results in lowered diversification rates. Triploid apomictic parthenogenesis might represent an exception, as

Diploid males support a two-step mechanism of endosymbiont-induced thelytoky in a parasitoid wasp [PDF]
BMC Evolutionary Biology, 2015 BackgroundHaplodiploidy, where females develop from diploid, fertilized eggs and males from haploid, unfertilized eggs, is abundant in some insect lineages.

True Parthenogenesis and Female-Biased Sex Ratios in Cicadomorpha and Fulgoromorpha (Hemiptera, Auchenorrhyncha) [PDF]
Insects, 2023 Insects are renowned for their remarkable diversity of reproductive modes. Among these, the largest non-holometabolous order, Hemiptera, stands out with one of the most diversified arrays of parthenogenesis modes observed among insects.

Absence of complementary sex determination in two Leptopilina species (Figitidae, Hymenoptera) and a reconsideration of its incompatibility with endosymbiont-induced thelytoky. [PDF]
Insect Sci, 2022 Complementary sex determination (CSD) is a widespread sex determination mechanism in haplodiploid Hymenoptera. Under CSD, sex is determined by the allelic state of one or multiple CSD loci.

Parthenogenetic Reproduction in Strumigenys Ants: An Update [PDF]
Insects, 2023 Parthenogenetic reproduction is a common feature for social Hymenoptera, as males typically develop from unfertilized eggs (arrhenotoky). Production of female offspring without the involvement of sperm (thelytoky) also exists but is rather exceptional as

Wolbachia-mediated parthenogenesis induction in the aphid hyperparasitoid Alloxysta brevis (Hymenoptera: Figitidae: Charipinae) [PDF]
Applied and Environmental MicrobiologyThelytokous parthenogenesis (thelytoky), in which females can produce female offspring without mating, can be caused by parthenogenesis-inducing endosymbiotic bacteria in the genus Wolbachia.
