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 ...

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 Modes in Onion Thrips (Thysanoptera: Thripidae) Populations from New York Onion Fields [PDF]

, 2017
Thrips exhibit different reproductive modes including thelytoky (females produced from unfertilized eggs), arrhenotoky (males produced from unfertilized eggs and females produced from fertilized eggs) and deuterotoky (females and males produced from ...

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.

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 ...

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.

Biogeography of oribatid mites (Acari) reflects their ancient origin and points to Southeast Asia as centre of radiation

Journal of Biogeography, Volume 51, Issue 11, Page 2211-2220, November 2024.
Abstract Aim Understanding the worldwide distribution of species has fascinated scientists at least since Alfred Russel Wallace. Global patterns of belowground biodiversity may fundamentally differ from those of aboveground organisms. Here, we examine the global pattern and potential mechanisms driving the endemism and overlap of a soil microarthropod ...

Risk assessment of Retithrips syriacus for the EU

EFSA Journal, Volume 22, Issue 4, April 2024.
Abstract Following a request from the European Commission, the EFSA Panel on Plant Health performed a quantitative risk assessment for the EU of Retithrips syriacus (Mayet) (Thysanoptera: Thripidae), a polyphagous thrips, regarded as a tropical/subtropical pest occurring in several countries of Africa, South America, Asia and in the EU in Cyprus.

Reproductive Biology of the Cape Honeybee: A Critique of Beekman et al: A critique of "Asexually Produced Cape Honeybee Queens (Apis mellifera capensis) Reproduce Sexually,” authors: Madeleine Beekman, Michael H. Allsopp, Julianne Lim, Frances Goudie, and Benjamin P. Oldroyd. Journal of Heredity. 2011:102(5):562-566 [PDF]

, 2017
Laying workers of the Cape honeybee parthenogenetically produce female offspring, whereas queens typically produce males. Beekman et al. confirm this observation, which has repeatedly been reported over the last 100 years including the notion that ...
