Ultrahistology of oogenesis and vitellogenesis in the spider mite Tetranychus urticae
Tissue and Cell, 1984Histology of the ovary of the spider mite Tetranychus urticae is described light and electron microscopically with special reference to oogenesis and vitellogenesis of this mite. Morphology of the ovary is comparable to the typical sac-like chelicerate ovary with oocytes protruding from the ovarian surface, thus resulting in a grape-like appearance ...

Structural Characterization of a Eukaryotic Cyanase from Tetranychus urticae
Journal of Agricultural and Food Chemistry, 2017The two-spotted spider mite Tetranychus urticae is a polyphagous agricultural pest and poses a high risk to global crop production as it is rapidly developing pesticide resistance. Genomic and transcriptomic analysis has revealed the presence of a remarkable cyanase gene in T. urticae and related mite species within the Acariformes lineage.

Microsatellite markers are frequently used to explore the population genetic structure of organisms. Spider mites (genus Tetranychus) are important agricultural pests. Several markers have been developed for T. urticae, but for other spider mites, few such markers are available, hampering studies of their population genetics.

Demography of the twospotted spider mite, Tetranychus urticae Koch
Oecologia, 1982A simple life table model was constructed for Tetranychus urticae in which daily survivorship of eggs and motil stages, fecundity, and development time was altered to assess the impact of each parameter on the intrinsic rate of increase. r. Interpretation of the trade-offs focused on management considerations.A second aspect of the study concerned age ...

Carotenoid metabolism in tetranychus urticae koch (Acari: Tetranychidae)
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1974Abstract 1. 1. Besides the plant carotenoids α-carotene, β-carotene, lutein, lutein-5,6-epoxide, violaxanthin and neoxanthin, wild-type Tetranychus urticae was found to contain esterified 3-hydroxy-4-keto-β-carotene, 3-hydroxy-4,4′-diketo-β-carotene and astaxanthin. 2. 2. From the study of the carotenoid content of seven pigment mutants of

Herbicides and the reproduction of Tetranychus urticae Koch
1991The herbicides, 3-amino-1,2,4-triazole (AT) and pure and commercial dinoseb-acetate were tested in the laboratory and on a semi-field scale in a bean plant-spider mite system (Phaseolus vulgaris L. and Tetranychus urticae Koch) using concentrations at and below the recommended rate.
