Toxicity of essential oils from Nordic plants against different pathogenic organisms and pests of cultivated plants

Annals of Applied Biology, EarlyView.
Plant essential oils (EOs) represent a potentially effective, safe, and eco‐friendly alternative to synthetic pesticides that cause negative effects for human health and the environment. The present study evaluated in airtight glass chambers the toxicity of vapours produced by EOs obtained from sweet gale, balsam poplar, Labrador tea, jack pine, and ...

Biology and Predation of Phytoseiulus macropilis on Tetranychus urticae

The Florida Entomologist, 1979
Phytoseiulus macropilis (Banks) was studied in the laboratory to determine its potential rate of population increase when fed on eggs of Tetranychus urticae Koch. The shortest developmental period was 4.7 days for males, and 5.8 days for females reared at 27 + 2?C and 90% + 5% RH under 12L:12D.

Physiological resistance alters behavioral response of Tetranychus urticae to acaricides [PDF]

Scientific Reports, 2019
AbstractMultiple acaricide resistance in Tetranychus urticae continues to threaten crop production globally, justifying the need to adequately study resistance for sustainable pest management. Most studies on acaricide resistance have focused on the acute contact toxicity of acaricides with little or no information on the behavioral responses elicited ...

Evaluation of cucumber (Cucumis sativus L.) accessions (cultivars and lines) against the two-spotted spider mite (Tetranychus urticae Koch.) and kanzawa spider mite (T. kanzawai Kishida, Acari: Tetranychidae) [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2006
Forty three cucumber (Cucumis sativus L.) accessions (cultivars and lines) were tested against the two-spotted spider mite (Tetranychus urticae Koch) and kanzawa spider mite (Tetranychus kanzawai Kishida). The highest number of T. urticae and T. kanzawai

The association of Mediterranean plant species with herbivorous arthropods and its effect on pest abundance in organic vineyards

Annals of Applied Biology, EarlyView.
We determined the associations of native Mediterranean plant species located around organic vineyards with species of Auchenorrhyncha and phytophagous tetranychid and tenuipalpid mites, including important vineyard pests: Jacobiasca lybica and Tetranychus urticae.

The Interactive Effect of Pesticides, Heat Stress, and Population on the Performance of a Mite Pest, Tetranychus Urticae

Journal of Applied Entomology, EarlyView.
ABSTRACT Global warming is a cause for concern and is predicted to diversely affect agricultural systems. One aspect of the predicted effects is the susceptibility of pests to chemical pesticides. It is therefore crucial to study the reaction of pests to different pesticide compounds under different temperatures in order to better predict how those ...

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 ...

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.
