Is only the first mating effective for females in the Kanzawa spider mite, Tetranychus kanzawai (Acari: Tetranychidae)? [PDF]
Although only the first mating is effective for females in Tetranychus urticae (Acari: Tetranychidae), it remains unclear whether this is also true for closely related species, such as T. kanzawai.

Spatial distribution and inbreeding in Tetranychus urticae
In group living, species spatial distribution results from responses to environmental heterogeneity and/or mutual interactions between individuals. These mutual interactions can be regulated by genetic and/or epigenetic factors. In this study, we focus on genetic factors and investigate how the spatial distribution of some individuals colonizing a new ...

The presence of webbing affects the oviposition rate of two-spotted spider mites, Tetranychus urticae (Acari: Tetranychidae) [PDF]
Several species of tetranychid mites including Tetranychus urticae Koch (Acari: Tetranychidae) construct complicated three-dimensional webs on plant leaves. These webs provide protection against biotic and abiotic stress.

A herbivorous mite down-regulates plant defence and produces web to exclude competitors. [PDF]
Herbivores may interact with each other through resource competition, but also through their impact on plant defence. We recently found that the spider mite Tetranychus evansi down-regulates plant defences in tomato plants, resulting in higher rates of ...

Variation in herbivory-induced volatiles among cucumber (Cucumis sativus L.) varieties has consequences for the attraction of carnivorous natural enemies [PDF]
In response to herbivory by arthropods, plants emit herbivory-induced volatiles that attract carnivorous enemies of the inducing herbivores. Here, we compared the attractiveness of eight cucumber varieties (Cucumis sativus L.) to Phytoseiulus persimilis ...
