Structure of Bee Communities in Marginal Lands of the Puget Sound, USA

Ecology and Evolution, Volume 15, Issue 9, September 2025.
We surveyed wild bee communities in marginal lands of the Puget Sound, USA. Bee communities were highly diverse and stable across seasons, but were variable within seasons. ABSTRACT Wild bee communities in urban ecosystems are often challenged by habitat fragmentation and low floral diversity.

Transcriptomic analysis of the mandibular gland genes associated with reproductive dominance in Apis mellifera capensis Esch. parasitic workers

Physiological Entomology, Volume 50, Issue 3, Page 233-244, September 2025.
Biosynthesis of the fatty acid components of the Apis mellifera mandibular gland pheromones takes place in a stepwise manner. Differential gene expression in the mandibular gland tissue of workers from two subspecies of African honey bees with differing reproductive potentials and at two age groups was investigated.

Endosymbiont-free ants: Molecular biological evidence that neither Wolbachia, Cardinium or any other bacterial endosymbionts play a role in thelytokous parthenogenesis in the harvester ant species, Messor barbarus and M. capitatus (Hymenoptera: Formicidae)

European Journal of Entomology, 2013
Thelytokous parthenogenesis is a type of sex determination in which females are produced from unfertilized eggs. Genetic and endosymbiont-induced forms of thelytoky have been described in the Hymenoptera. Our study has revealed that Wolbachia, Cardinium,

Reproductive Transitions and Sperm Utilisation in a Facultatively Parthenogenetic Stick Insect

Ecology and Evolution, Volume 15, Issue 7, July 2025.
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 ...

Detection of Wolbachia bacterium in Iranian strain of Trichogramma brassicae (Hym., Trichogrammatidae) [PDF]

نامه انجمن حشره‌شناسی ایران, 2013
Wolbachia (α-proteobacteria) strains are intracellular endosymbiont bacteria found in reproductive tissues of many arthropod species. In Trichogramma wasps, thelytokous parthenogenesis is mostly induced by this bacterium which inherited transovarially ...

Newcomers and Old Friends: Long‐Distance and Bridgehead Introductions Both Contribute to the Recent Invasion of the Little Fire Ant in Southern Europe

Diversity and Distributions, Volume 31, Issue 7, July 2025.
ABSTRACT Aim Biological invasions result from the combination of (i) population dispersal opportunities and (ii) adaptations to the recipient environment. Identifying complex migration histories, made of long‐distance dispersal from the native range and secondary introductions, or genetic patterns indicative of adaptation is crucial to build coherent ...

Pest categorisation of Coccus viridis

EFSA Journal, Volume 23, Issue 7, July 2025.
Abstract The EFSA Panel on Plant Health performed a pest categorisation of Coccus viridis (Hemiptera: Coccidae), the green coffee scale, for the territory of the European Union (EU), following the commodity risk assessment of Jasminum polyanthum from Uganda, in which C. viridis was identified as a pest of possible concern to the EU.

Dysdera parthenogenetica sp. nov. (Araneae, Dysderidae): A Unique Case of Parthenogenesis in Spiders

Journal of Zoological Systematics and Evolutionary Research, Volume 2025, Issue 1, 2025.
We studied the parthenogenetic lineages of the spider Dysdera hungarica (Araneae: Dysderidae). Based on our data, we consider them to constitute a separate taxon, Dysdera parthenogenetica sp. nov. Morphologically, the new species differs mainly by slightly reduced female copulatory organs.

No evidence of parthenogenesis-inducing bacteria involved in Thripoctenus javae thelytoky: an unusual finding in Chalcidoidea

, 2016
All Hymenoptera have a haplodiploid mode of sex determination. Although most species reproduce by arrhenotokous parthenogenesis, there are many thelytokous species, in which unfertilized eggs develop into diploid females.

Phryssonotus novaehollandiae Silvestri, 1923: the sole Australian representative of the millipede Family Synxenidae

Soil Organisms, 2009
Examination of synxenid millipedes from a number of collections confirms that Phryssonotus novaehollandiae is the sole representative of the genus and family in Australia. P.
