Environmental stress influences reproductive success in male spider mites

Ecological Entomology, EarlyView.
This experiment explores how male juvenile food stress impacts reproductive traits in the haplodiploid spider mite Tetranychus urticae. Males exposed to juvenile food stress had lower reproductive success and females mated to these males also suffered reduced fitness as they were not able to produce optimal offspring sex ratios. The negative effects of

Population models for threshold-based control of Tetranychus urticae in small-scale Kenyan tomato fields and for evaluating weather and host plant species effects [PDF]

, 2006
The spatial distribution of motile life stages of the two-spotted spider mite Tetranychus urticae Koch in Kenyan small-scale tomato fields was described by Taylor's power law and an enumerative sampling plan was designed for research purposes.

Ecological predictors of plant responses to sequential herbivory: a meta‐analysis

New Phytologist, EarlyView.
Summary Plants evolved alongside herbivores for over 400 million years and show remarkable plasticity in responses to attack by multiple herbivores. However, it is often debated which herbivore traits predict plant responses and it is poorly understood how plant life‐history traits contribute to the variation observed in plant responses.

Genome wide gene-expression analysis of facultative reproductive diapause in the two-spotted spider mite Tetranychus urticae [PDF]

, 2013
Background: Diapause or developmental arrest, is one of the major adaptations that allows mites and insects to survive unfavorable conditions. Diapause evokes a number of physiological, morphological and molecular modifications.

Drought and Herbivory Drive Physiological and Phytohormonal Changes in Soybean (Glycine max Merril): Insights From a Meta‐Analysis

Plant, Cell &Environment, EarlyView.
ABSTRACT With climate change, abiotic and biotic stresses such as drought and herbivory are predicted to further diminish agricultural productivity. Soybean (Glycine max [L.] Merrill), a crop of global economic importance, is vulnerable to both. However, the interactive effects of drought and herbivory on soybeans haven't been explored, especially ...

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

bioRxiv, 2019
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 ...

Acaricidal Activities of Extracts of Kochia scoparia against Tetranychus urticae, Tetranychus cinnabarinus, and Tetranychus viennensis (Acari: Tetranychidae) [PDF]

Journal of Economic Entomology, 2006
Extracts of an annual herbaceous plant, Kochia scoparia (L.) Schrad (Macrophomina), were bioassayed to determine their acaricidal activities against Tetranychus urticae Koch, Tetranychus cinnabarinus (Boisduval), and Tetranychus viennensis Zacher (Acari: Tetranychidae) in the laboratory.

Tetranychus urticae changes its oviposition pattern in the presence of the predatory mites, Phytoseiulus persimilis and Typhlodromus bagdasarjani

Acta Biologica, 2019
Oviposition behaviors in herbivorous mites are affected by several factors i.e. food availability for juveniles and reduced predation risks. We used the twospotted spider mite, Tetranychus urticae Koch (Tetranychidae) to find out whether the previous ...
