Influence of Phase Change on Parthenogenesis in the Migratory Locust: A Behavioral Analysis [PDF]

open access: yesInsects
The migratory locust (Locusta migratoria), is a destructive pest in agriculture and ecological conservation, characterized by its unique phase polyphenism (phase change).

Wolbachia-mediated parthenogenesis induction in the aphid hyperparasitoid Alloxysta brevis (Hymenoptera: Figitidae: Charipinae) [PDF]

open access: yesApplied and Environmental Microbiology
Thelytokous parthenogenesis (thelytoky), in which females can produce female offspring without mating, can be caused by parthenogenesis-inducing endosymbiotic bacteria in the genus Wolbachia.

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 ...

First report of recurrent parthenogenesis as an adaptive reproductive strategy in the endangered common smooth-hound shark Mustelus mustelus [PDF]

open access: yesScientific Reports
Parthenogenesis, or virgin birth, describes a mode of reproduction where an egg develops into an offspring without fertilization, and is observed across various vertebrate taxa, excluding mammals.

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.

Facultative parthenogenesis: a transient state in transitions between sex and obligate asexuality in stick insects?

open access: yesPeer Community Journal, 2023
Transitions from obligate sex to obligate parthenogenesis have occurred repeatedly across the tree of life. Whether these transitions occur abruptly or via a transient phase of facultative parthenogenesis is rarely known.

Protocol for screening facultative parthenogenesis in Drosophila

open access: yesSTAR Protocols, 2023
Summary: Most species of sexually reproducing Drosophila are capable of some degree of facultative parthenogenesis, which involves the initiation of development in an unfertilized egg.

True Parthenogenesis and Female-Biased Sex Ratios in Cicadomorpha and Fulgoromorpha (Hemiptera, Auchenorrhyncha)

open access: yesInsects, 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.
