The twospotted spider mite, Tetranychus urticae Koch, is a worldwide pest of numerous agronomic and horticultural plants. Sulfur fungicides are known to induce outbreaks of this pest on several crops, although mechanisms associated with sulfur-induced mite outbreaks are largely unknown. Studies were conducted during 2007-2009 in Oregon and Washington hop yards to evaluate the effect of timing ...

the entomopathogenic fungus beauveria bassiana (bals.) vuill. is one of the important arthropod pathogens that can play an important role in the regulation of mite populations in agricultural ecosystems. in this study, the combined effect of a native isolate of fungus b. bassiana (eut105) and ether-extract of plant, ginkgo biloba was evaluated against the two-spotted spider mite, tetranychus ur...

The two-spotted spider mite, Tetranychus urticae Koch, is a constant threat to sustainable production of numerous economically important crops globally. Management T. heavily reliant on the application synthetic acaricides. However, has rapidly developed resistance most acaricides available for its control due very broad host plant range, extremely short lifecycle, high fecundity, arrhenotokous...

Two spotted spider mite (TSSM), Tetranychus urticae Koch, is an important pests on bean in Markazi Province (center of Iran). To evaluate the bioacaricidal activity of extracts of three essential oils of thyme (Thymus vulgaris), lavender (Lavandula officinalis)  and eucalyptus (Eucalyptus camaldulensis) against T. urticae on cherry bean (Vigna unguiculta subsp. sinensis), five different concent...

In North Africa, Tetranychus urticae Koch, 1836 represents one of the most destructive generalists among mite herbivores. Unfortunately, it is a source important annual casualties in crop production. It phytophagous that can feed on hundreds host plants and produces significant damage. The control T. Africa has been principally based acaricide sprays. However, new alternative methods have shown...

two-spotted spider mite (tetranychus urticae koch), is one of the most seriously important  polyphagous pests that causes considerable damage to agricultural crops. in recent years, due to problems associated with the use of synthetic pesticides, herbal essential oils have received due attention as natural plant pest control compounds. in the present study, repellency effect of herbal plant ess...

Tetranychus urticae Koch, is known as a two-spotted spider mite and the most obtrusive polyphagous non-insect pest that causes havoc on horticultural crops. Cucumber cultivation threatened by variety of infestations, among which mites cause damage to crop. The efficiency six different chemical acaricides against T. in cucumber grown polyhouse was examined. results acaricide evaluation trial rev...
