Citrus defense responses against Tetranychus urticae [PDF]

, 2019
En la presente tesis doctoral se han estudiado los mecanismos de defensa de cítricos frente al ataque de T. urticae a diferentes niveles. En primer lugar se analizaron los mecanismos de defensa directa utilizando dos patrones con diferente nivel de susceptibilidad.

Glufosinate Ammonium Suppresses Tetranychus urticae in Cotton

Journal of Cotton Science, 2018
Twospotted spider mites, Tetranychus urticae, are an important agricultural pest of many field crops worldwide. Insecticides and acaricides play a primary role in controlling T. urticae populations on agricultural crops. Here, we used greenhouse and field applied foliar spray tests and leaf dip bioassays to examine the susceptibility of T.

Niche Breadth and Olfactory Context Shape Informed Passive Dispersal

Ecology Letters, Volume 29, Issue 4, April 2026.
Experimental evolution reveals that niche breadth modulates informed passive dispersal in phytophagous mites through divergent strategies. While generalists optimise take‐off based on target cue familiarity and signal‐to‐noise ratios, specialists primarily track current host quality to trigger departure.

Fitness costs of key point mutations that underlie acaricide target-site resistance in the two-spotted spider mite Tetranychus urticae [PDF]

, 2018
The frequency of insecticide/acaricide target-site resistance is increasing in arthropod pest populations and is typically underpinned by single point mutations that affect the binding strength between the insecticide/acaricide and its target-site ...

Ecological predictors of plant responses to sequential herbivory: a meta‐analysis

New Phytologist, Volume 250, Issue 2, Page 1128-1140, April 2026.
Summary Plants evolved alongside herbivores for over 400 million years and show remarkable plasticity in responses to attack by multiple herbivores. However, it is often debated which herbivore traits predict plant responses and it is poorly understood how plant life‐history traits contribute to the variation observed in plant responses.

Chemical composition and acaricidal activity of the leaf and fruit essential oils of Protium heptaphyllum (Aubl.) Marchand (Burseraceae) Composição química e atividade acaricida do óleo essencial das folhas e frutos de Protium heptaphyllum (Aubl.) Marchand (Burseraceae)

Acta Amazonica, 2007
Essential oils from leaves and fruits of Protiumheptaphyllum collected in Tamandaré beach Pernambuco/Brazil were analysed by GC/MS and tested for toxicity and repellent effect against the two spotted spider mite (Tetranychus urticae).

Why do herbivorous mites suppress plant defenses? [PDF]

, 2018
Plants have evolved numerous defensive traits that enable them to resist herbivores. In turn, this resistance has selected for herbivores that can cope with defenses by either avoiding, resisting or suppressing them. Several species of herbivorous mites,

Innovative Biopesticides: Nanoformulation of Mentha Piperita L. and Satureja Montana L. Essential Oils for Controlling the Cotton Bollworm, Helicoverpa armigera Hub.

Nano Select, Volume 7, Issue 3, March 2026.
Chitosan‐based nanocapsules loaded with Mentha piperita and Satureja montana essential oils were evaluated for insecticidal efficacy against Helicoverpa armigera larvae. Nanoformulations demonstrated controlled release, prolonged toxicity, and sublethal effects, offering an eco‐friendly alternative to conventional pesticides.

Controle biológico do ácaro rajado com ácaros predadores fitoseídeos (Acari: Tetranychidae, Phytoseiidae) em culturas de pepino e morango Biological control of the two-spotted spider mite (Acari: Tetranychidae, Phytoseiidae) in cucumber and strawberry crops

Scientia Agricola, 1994
O ácaro rajado, Tetranychus urticae Koch, é considerado uma das principais pragas de hortaliças e várias outras culturas no Brasil, em áreas onde um considerável volume de acaricidas é anualmente empregado no seu controle.
