Prevalence of sensitization to Tetranychus urticae in greenhouse workers

Clinical & Experimental Allergy, 2000
Background Tetranychus urticae (TU) is a macroscopic mite which infests a large number of plants of economic interest worldwide. It has recently been described as a cause of occupational allergic disease in greenhouse workers. However, there are no epidemiological data concerning the prevalence of TU allergy in an unselected exposed population ...

Fogging can control Tetranychus urticae on greenhouse cucumbers

Journal of Pest Science, 2004
The effect of a fogging system on interactions between Tetranychus urticae and Phytoseiulus persimilis was studied in two cucumber greenhouses in northern Italy. The greenhouses were divided into two compartments, one (referred to as fog area) was humidified using a fogging system and the other was not humidified (no fog area).

Occupational allergy in greenhouse workers: sensitization to Tetranychus urticae

Clinical <html_ent glyph="@amp;" ascii="&amp;"/> Experimental Allergy, 1997
SummaryBackground Tetranychus urticae (TU) is a macroscopic mite which is found infesting a large number of plants of economic interest. It has rarely been described as a cause of occupational allergic disease in agricultural workers.Objective To describe TU sensitization in greenhouse workers attending the outpatient allergy unit and its clinical ...

Structural Characterization of a Eukaryotic Cyanase from Tetranychus urticae

Journal of Agricultural and Food Chemistry, 2017
The 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.

Acaricide-Mediated Competition Between the Sibling Species Tetranychus cinnabarinus and Tetranychus urticae

Journal of Economic Entomology, 2018
The carmine spider mite (Tetranychus cinnabarinus [Acarifonnes: Tetranychidae]) and the two-spotted spider mite (Tetranychus urticae [Acarifonnes: Tetranychidae]) are two notorious pests of agricultural crops. Control of these pests has been dependent upon using different kinds of acaricides.

Ultrahistology of oogenesis and vitellogenesis in the spider mite Tetranychus urticae

Tissue and Cell, 1984
Histology 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 ...

The silk road of Tetranychus urticae: is it a single or a double lane?

Experimental and Applied Acarology, 2012
Tetranychus urticae (Acari: Tetranychidae) is a phytophagous mite that forms huge colonies. All active members of a colony (immatures and matures, females and males) spin silken threads. These mites construct a common web that protects the colony from external aggression.

Demography of the twospotted spider mite, Tetranychus urticae Koch

Oecologia, 1982
A 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 ...

Development of microsatellite markers for six Tetranychus species by transfer from Tetranychus urticae genome

Experimental and Applied Acarology, 2016
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.

Herbicides and the reproduction of Tetranychus urticae Koch

1991
The 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.
