Asexual reproduction in introduced and native populations of the ant Cerapachys biroi [PDF]

open access: yes, 2012
Asexual reproduction is particularly common among introduced species, probably because it helps to overcome the negative effects associated with low population den-sities during colonization.

Getting more than a fair share: nutrition of worker larvae related to social parasitism in the Cape honey bee Apis mellifera capensis [PDF]

open access: yes, 2002
Besides activation of ovaries and thelytokous reproduction of Cape workers, larval nutrition is an important aspect in parasitism of the African honey bee.

Facultative parthenogenesis in California condors [PDF]

open access: yes, 2021
Parthenogenesis is a relatively rare event in birds, documented in unfertilized eggs from columbid, galliform, and passerine females with no access to males.

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

Observations on the Burrow Structures and Larval Behavior of Ephoron shigae (Takahashi, 1924) (Ephemeroptera: Polymitarcyidae) in River Sediments

open access: yesInternational Review of Hydrobiology, Volume 111, Issue 2, December 2026.
ABSTRACT The larvae of the mayfly Ephoron shigae (Takahashi, 1924) (Ephemeroptera: Polymitarcyidae) inhabit distinctive U‐shaped burrows in river and lake sediments, yet their ecology remains poorly documented. Using newly developed mechatronic technology, we obtained continuous observations that revealed new aspects of larval behavior.

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 ...

Population Dynamics of Greenhouse Thrips (Heliothrips haemorrhoidalis) on Avocado Under Single and Combined Predator Releases

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 3, September 2026.
The greenhouse thrips, Heliothrips haemorrhoidalis (Bouché, 1833), is an important avocado pest in New Zealand, where repeated infestations reduce leaf quality and tree vigour. To assess biological control stability under different predator assemblages, this study evaluated thrips population dynamics and predator survival across two sequential phases ...

Investigating the Possibility of Wolbachia‐ and Cardinium‐Induced Parthenogenesis in Two Mite Species

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 3, September 2026.
In arthropods, thelytokous parthenogenesis, in which females develop from unfertilised eggs, is often associated with reproductive manipulation by endosymbiotic bacteria such as Wolbachia and Cardinium. This study investigated whether thelytokous parthenogenesis in two mite species, Amblyseius herbicolus (Phytoseiidae) and Czenspinskia ...
