Testing for collective choices in the two-spotted spider mite
Experimental and Applied Acarology, 2012Silk is a vector for collective behaviour in many spinning arthropods, including social spiders, social caterpillars, and some spider mites. In this study, the potential for silk-mediated collective choices is evaluated for the two-spotted spider mite Tetranychus urticae.

UV tolerance in the two-spotted spider mite, Tetranychus urticae
Journal of Insect Physiology, 2009The two-spotted spider mite, Tetranychus urticae was exposed to UV-C (250 nm), UV-B (300 nm), and UV-A (350 nm). In non-diapausing females, the median effective doses for 50% mortality plus escape incidence (ED(50)) were 21 (UV-C) and 104 kJm(-2) (UV-B); those for 50% oviposition rate in continuous darkness-treated mites were 6.2 (UV-C) and 41 kJm(-2) (

Apple, European Red Mite and Two Spotted Spider Mite Control, 1992
Insecticide and Acaricide Tests, 1993Abstract This test was conducted in an orchard with trees of mixed ages near Malaga, Washington. The experimental design was randomized complete block with nine treatments and four single tree replications. All trees were treated with Asana 0.66 EC at 2 oz/100 gal, 200 gal/acre on 18 Jun to eliminate predatory mites. Blocks were based on

Two-spotted spider mite on outdoor crops
1992Two-spotted spider mite (Tetranychus urticae Koch), also known as red spider mite, is primarily a pest of protected crops (see page 361), but it can damage several crops outdoors, particularly in hot, dry summers. It has a wide host range and may spread from crop to crop by way of weeds or hedgerow plants.

Malathion Synergism Against Organophosphate-Resistant Two-Spotted Spider Mites
Journal of Economic Entomology, 1965Organophosphate resistant two-spotted spider mites, Tetranychns telarius (L.), were about 3.5 times more susceptible to solutions of malathion containing chemicals known to be ali-esterase inhibitors than to solutions of malathion alone. These chemicals alone were acaricidal at concentrations higher than those necessary to demonstrate this synergistic ...

Greenhouse Ornamentals, Two-Spotted Spider Mite Control, California, 1978
Insecticide and Acaricide Tests, 1979Abstract An experiment was conducted to evaluate the efficacy of 9 experimental and 2 standard acaracides for control of two-spotted spider mites. Plants were maintained in 6-inch pots on raised greenhouse benches. A treatment consisted of 1 plant and was replicated 4 times on red ti and 5 times on neanthe bella palm. Plants were sprayed

Nitrogen Availability and Defense of Tomato Against Two-spotted Spider Mite
Journal of Chemical Ecology, 2000The aim of this work was to study how nitrogen availability affects within-plant allocation to growth and secondary metabolites and how this allocation affects host selection by herbivores. Tomato plants (Lycopersicon esculentum) were grown at six levels of nitrogen availability.

Acaricidal activity of spinosad and abamectin against two-spotted spider mites
Experimental and Applied Acarology, 2007Spinosad is a bioinsecticide with a high degree of selective toxicity towards insects of different orders, but its toxicity towards the two-spotted spider mite (TSSM), Tetranychus urticae Koch (Acari: Tetranychidae) is under debate. In this study, we compared the acaricidal properties of spinosad with the commercial bioacaricide abamectin on the life ...
