The presence of webbing affects the oviposition rate of two-spotted spider mites, Tetranychus urticae (Acari: Tetranychidae) [PDF]

open access: yes, 2009
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.

Survival and developmental characteristics of the predatory bug Orius similis (Hemiptera: Anthocoridae) fed on Tetranychus cinnabarinus (Acari: Tetranychidae) at three constant temperatures

open access: yesEuropean Journal of Entomology, 2012
Developmental characteristics of the predatory bug Orius similis fed on Tetranychus cinnabarinus were investigated at three constant temperatures (25, 28, and 31°C) under laboratory conditions (75±5% relative humidity and a 14L : 10D photoperiod).

Role of excreta in predator avoidance by the Kanzawa spider mite, Tetranychus kanzawai (Acari: Tetranychidae)

open access: yesEuropean Journal of Entomology, 2008
The Kanzawa spider mite, Tetranychus kanzawai (Acari: Tetranychidae) constructs webs over leaf surfaces and usually lives under these webs. T. kanzawai produces two types of excreta, black and yellow pellets, and uses its webs as a place for excretion. T.

High-resolution QTL mapping in Tetranychus urticae reveals acaricide-specific responses and common target-site resistance after selection by different METI-I acaricides [PDF]

open access: yes, 2019
Arthropod herbivores cause dramatic crop losses, and frequent pesticide use has led to widespread resistance in numerous species. One such species, the two-spotted spider mite, Tetranychus urticae, is an extreme generalist herbivore and a major worldwide

Survey of Predators Associated With European Red Mite (\u3ci\u3ePanonychus Ulmi\u3c/i\u3e; Acari: Tetranychidae) in Ohio Apple Orchards [PDF]

open access: yes, 2017
A survey was conducted to identify the types and relative abundance of predatory arthropods associated with Panonychus ulmi in 21 Ohio apple orchards. Mite populations were sampled by leaf brushing, and insects and spiders were sampled by limb jarring. A

Bioactivity Profiling of Coronarin A and Villosin Isolated From Hedychium coronarium J. Koenig: Acaricidal, Nematicidal, and Antifungal Potential. [PDF]

open access: yesChem Biodivers
The graphical abstract illustrates the flowchart for the isolation and evaluation of bioactive compounds from Hedychium coronarium. Crude extracts were obtained via cold percolation from the aerial parts (flowers, leaves, and stems) using dichloromethane (DCM) and from the rhizomes using chloroform.
