Of all shapes and sizes: a theoretical framework for animal‐mediated terrestrial heterogeneity across scales

open access: yesEcography, EarlyView.
Animals redistribute elements throughout their lives by depositing wastes and carcasses. Growing evidence shows that these zoogeochemical processes enhance landscape diversity and heterogeneity worldwide. We provide a descriptive framework for understanding how direct animal depositions (i.e.

Potential volatiles emitted from jasmine plants infested by Tetranychus urticae (Acari: Tetranychidae) and its attraction to predatory Scolothrips sexmaculatus (Thysanoptera: Thripidae)

open access: yesPersian Journal of Acarology, 2023
Herbivore-induced volatiles were extracted from fresh healthy jasmine plants (Jasminum sambac L.) and infested jasmine plants damaged by two-spotted spider mite, Tetranychus urticae and analyzed through Gas Chromatography-Mass spectrometry (GC-MS) to ...

Gene and Genome Duplication in Spiders

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In chelicerates whole genome duplications (WGDs) were identified in distinct groups. While there is evidence that Xiphosurans/horseshoe crabs had three rounds of WGD and arachnopulmonates (e.g. spiders and scorpions) had one WGD, in many other arachnid groups no WGD was identified.

Impacts of climate change on tomato, a notorious pest and its natural enemy: small scale agriculture at higher risk

open access: yesEnvironmental Research Letters, 2019
Climate change (CC) clearly impacts food production, but risks on the climatic suitability of agricultural areas for vegetable crops, their pests and associated natural enemies are largely unexplored.

Impact of Early Infestation of Two-Spotted Spider Mites (Tetranychus urticae) on Cotton Growth and Yield [PDF]

open access: yes, 2014
Two-spotted spider mites (Tetranychus urticae Koch, 1836) are pests of vegetables, ornamentals, and row crops around the world. Two-spotted spider mites have become an important long-season pests of cotton, causing injury to cotton from an early ...

The continuing significance of chiral agrochemicals

open access: yesPest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Targeted mutagenesis using CRISPR-Cas9 in the chelicerate herbivore Tetranychus urticae [PDF]

open access: yes, 2020
The use of CRISPR-Cas9 has revolutionized functional genetic work in many organisms, including more and more insect species. However, successful gene editing or genetic transformation has not yet been reported for chelicerates, the second largest group ...

Proteolytic stabilization of a spider venom peptide results in an orally active bioinsecticide

open access: yesPest Management Science, EarlyView.
Selective editing out of an insect gut protease cleavage site renders a spider‐derived insecticidal peptide active by ingestion by insect pests. Abstract BACKGROUND The toxin peptide U1‐AGTX‐Ta1b from the Hobo spider, Eratigena agrestis (Walckenaer, 1802), was studied to determine its potential to serve as a bioinsecticide.

Effect of fungus Lecanicillium lecanii and bacteria Bacillus thuringiensis, Streptomyces avermitilis on two-spotted spider mite Tetranychus urticae (Acari: Tetranychidae) and predatory mite Phytoseiulus persimilis (Acari: Phytoseiidae)

open access: yesJournal of Plant Protection Research, 2020
The efficacy of the fungus Lecanicillium lecanii and two bacteria, Bacillus thuringiensis and Streptomyces avermitilis against the two-spotted spider mite Tetranychus urticae Koch and side effects on its predatory mite Phytoseiulus persimilis A.-H. was
