Evaluation of asexual Wolbachia-infected Trichogramma brassicae performance in greenhouse and field conditions [PDF]
In some Trichogramma species, parthenogenesis is mostly induced by intracellular symbiotic Wolbachia bacteria. Populations of this egg parasitoid wasp that produce more female progeny can potentially have higher fitness.

Diet-Induced Developmental and Morphological Plasticity in a Thelytokous Predatory Mite <i>Amblyseius herbicolus</i> (Chant) (Acari: Phytoseiidae). [PDF]
This study investigated how variation in prey consumption influences immature development and adult morphometric traits in the predatory mite Amblyseius herbicolus. Mites that ate more prey attained a larger size at maturity but did not develop more rapidly. Several morphometric traits were also significantly influenced by diet.

Comprehensive analysis of male-free reproduction in Monomorium triviale (Formicidae: Myrmicinae).
We report comprehensive evidence for obligatory thelytokous parthenogenesis in an ant Monomorium triviale. This species is characterized by distinct queen-worker dimorphism with strict reproductive division of labor: queens produce both workers and new ...

Reproductive Transitions and Sperm Utilisation in a Facultatively Parthenogenetic Stick Insect. [PDF]
Facultative parthenogenesis enables females to switch from asexual (parthenogenetic) to sexual reproduction after mating, but the process of fertilisation is poorly understood in such animals. It is unknown whether switching reproductive modes requires changes in the eggs themselves, delaying the transition from laying unfertilised to fertilised eggs ...

No Mate, No Problem: Molecular Mechanisms Involved in Parthenogenesis in the Cosmopolitan Earthworm Aporrectodea trapezoides (Annelida, Clitellata). [PDF]
ABSTRACT Approximately, 40% of earthworm species can reproduce by parthenogenesis. This is the case for the cosmopolitan species, Aporrectodea trapezoides, although sexual forms have been described sporadically. We analyse the genotypes and microbiomes of 30 individuals from four localities where both forms appear in order to understand the ...

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.

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.

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 ...

What mechanistic factors affect thelytokous parthenogenesis in Apis mellifera caponises queens? [PDF]
The Cape honey bee (Capensis) is unusual in that workers can produce viable female offspring via thelytokous parthenogenesis. In contrast, mated queens never reproduce thelytokously, even though they could benefit from doing so when generating daughter queens.

A comparative study on the functional response of Wolbachia-infected and uninfected forms of the parasitoid wasp Trichogramma brassicae [PDF]
Trichogramma species (Hymenoptera: Trichogrammatidae) are haplo-diploid egg parasitoids that are frequently used as biological control agents against lepidopteran pests.
