Mouthpart morphology and feeding structures in the palaeocharinid trigonotarbids of the Rhynie chert: insights from comparisons to modern arachnids

open access: yesPalaeontology, Volume 67, Issue 4, July/August 2024.
Abstract Trigonotarbida, an extinct order of spider‐like arachnids, were significant predators between the late Silurian and early Permian. Characterized by their segmented opisthosoma, clasp‐knife chelicera, and paired book lungs, they played a pivotal role in the formation of Early Devonian terrestrial ecosystems.

The “elongate chelicera problem”: A virtual approach in an extinct pterygotid sea scorpion from a 3D kinematic point of view

open access: yesEcology and Evolution, Volume 14, Issue 5, May 2024.
How pterygotid sea scorpions used their tripartite elongate cheliceres to get prey items close to the mouth region remains a conundrum. We applied four different 3D kinematic settings with regard to insertion and orientation of the cheliceres to examine the most likely way this was realized.

Pest categorisation of Calepitrimerus baileyi

open access: yesEFSA Journal, Volume 22, Issue 5, May 2024.
Abstract The EFSA Panel on Plant Health performed a pest categorisation of Bailey's rust mite, Calepitrimerus baileyi Keifer (Acariformes: Eriophyidae), following the commodity risk assessment of Malus domestica plants from Türkiye performed by EFSA, in which C. baileyi was identified as a pest of possible concern to the European Union.

Genome-Wide Identification of Long Non-coding RNAs in the Gravid Ectoparasite Varroa destructor

open access: yesFrontiers in Genetics, 2020
Long non-coding RNAs (lncRNAs) emerge as critical regulators across a wide variety of biological functions in living organisms. However, to date, no systematic characterization of lncRNAs has been investigated in the ectoparasitic mite Varroa destructor,

Design and partial validation of novel eDNA qPCR assays for three common North American tick (Arachnida: Ixodida) species

open access: yesEnvironmental DNA, Volume 6, Issue 2, March–April 2024.
Abstract The range expansion of ticks to higher latitudes poses a severe threat to human health exposing human populations who had no prior contact with ticks to several harmful tick‐borne diseases. Early detection of ticks in new areas is critical to help inform the public and medical professionals of the dangers associated with tick encounters ...

Lethal and sublethal effects of carlina oxide on Tetranychus urticae (Acari: Tetranychidae) and Neoseiulus californicus (Acari: Phytoseiidae)

open access: yesPest Management Science, Volume 80, Issue 3, Page 967-977, March 2024.
Carlina oxide is very toxic toward mobile stages of Tetranychus urticae, also showing a high ovicidal effect even at low concentrations. By contrast, it is harmless for the phytoseiid Neoseiulus californicus but a strong repellent effect was recorded during the first 48 h. Abstract BACKGROUND Tetranychus urticae Koch, is a polyphagous and damaging pest,
