Longevity, fertility, and average eggs viability of parthenogenetic females of Cladomorphus phyllinus Gray (Phasmatodea - Phasmatidae)

open access: yesEntomoBrasilis, 2022
The order Phasmatodea includes insects known as stick insects. In Brazil, few taxonomic, ecological or evolutionary studies have been published in recent years, the reason is related to the few number of researchers dedicated to this particular group ...

Reproduction in the spider mite Oligonychus yothersi (Acari: Tetranychidae) [PDF]

open access: yesAnais da Academia Brasileira de Ciências
In this work we reported injuries caused by the spider mite Oligonychus yothersi on Vitis vinifera leaves and we also investigate the sex ratio of this species under laboratory conditions. To access the aspects regarding reproduction, females were placed

Viable Triploid Honey Bees (Apis mellifera capensis) Are Reliably Produced in the Progeny of CO2 Narcotised Queens

open access: yesG3: 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

Gradual, temperature-induced change of secondary sexual characteristics in Trichogramma pretiosum infected with parthenogenesis-inducing Wolbachia [PDF]

open access: yesPeerJ, 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

Genetic diversity and the phylogeography of parthenogenesis: comparing bisexual and thelytokous populations of Nemasoma varicorne (Diplopoda: Nemasomatidae) in Denmark [PDF]

open access: yesHereditas, 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)

open access: yesEuropean 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 ...

Potential Drivers of Successful Biocontrol: A Perspective on Parasitoids

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 1, March 2026.
Parasitoids are central to classical biological control, yet predicting their long‐term effectiveness post release remains challenging. In Aotearoa New Zealand, three Microctonus (Hymenoptera: Braconidae) species have been used against pest weevils, but key aspects of their biology remain poorly understood.

Evolution of reproductive mode variation and host associations in a sexual-asexual complex of aphid parasitoids

open access: yesBMC Evolutionary Biology, 2011
Background The Lysiphlebus fabarum group is a taxonomically poorly resolved complex of aphid parasitoids, presently split into three described species that comprise sexual (arrhenotokous) and asexual (thelytokous) lineages of unknown relationship ...

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.

Wolbachia Infection in Populations of Ostrinia furnacalis: Diversity, Prevalence, Phylogeny and Evidence for Horizontal Transmission

open access: yesJournal of Integrative Agriculture, 2013
Wolbachia are maternally inherited endosymbiotic bacteria infecting a wide range of arthropods and filarial nematodes. They can induce various reproduction alterations in their hosts, including thelytokous parthenogenesis, cytoplasmic incompatibility (CI)
