Abamectin, Hexythiazox and Spiromesifen Resistance in Populations of Tetranychus urticae Koch (Acari:Tetranychidae) Collected from Cucumber Greenhouses in Tokat Province

open access: yesTurkish Journal of Agriculture: Food Science and Technology, 2022
Tetranychus urticae Koch (Acari: Tetranychidae) is one of the most important pests in greenhouses. This harmful pest has rapidly developed high resistance to many classes of acaricides. In this study, T.

Acaricidal activity of Annonaceae fractions against Tetranychus tumidus and Tetranychus urticae (Acari: Tetranychidae) and the metabolite profile of Duguetia lanceolata (Annonaceae) using GC-MS

open access: yesSemina: Ciências Agrárias, 2015
Species of the Tetranychus genus feed on plant tissues, which reduces the rate of photosynthesis and can lead to the death of plant tissues. As a result, considerable production losses are caused by these arthropods.

Pest species diversity enhances control of spider mites and whiteflies by a generalist phytoseiid predator [PDF]

open access: yes, 2010
To test the hypothesis that pest species diversity enhances biological pest control with generalist predators, we studied the dynamics of three major pest species on greenhouse cucumber: Western flower thrips, Frankliniella occidentalis (Pergande ...

Spatial distribution and inbreeding in Tetranychus urticae

open access: yesComptes Rendus. Biologies, 2009
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 ...

Is only the first mating effective for females in the Kanzawa spider mite, Tetranychus kanzawai (Acari: Tetranychidae)? [PDF]

open access: yes, 2008
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.
