The acaricidial, persistent and ovicidal activities of four methanolic extracts of Anisosciadium orientale DC., Scaligeria meifolia Boiss., Trigonella elliptica Boiss. and Ptelea viscosa L. were assessed against the two-spotted spider mite, Tetranychus urticae Koch, in a bioassay under laboratory conditions. All the extracts exhibited significant adult female mite mortality as compared to control and S. meifolia extract showed highest toxicity based on the LC50 when compared with the other… 

Acaricidal and repellent effects of Aloe vera L. leaf extracts against Tetranychus urticae Koch (Acari: (Tetranychidae)

The two-spotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae) is a cosmopolitan pest that causes considerable damage to vegetables, fruit and flower plants. The acaricidal, ovicidal

Potential control of two-spotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae) by crude extracts of Duabanga grandiflora (Lythraceae) and Diospyros cauliflora (Ebenaceae).

Results indicated that D. grandiflora crude methanol extract exhibited the strongest repellency and oviposition deterrent activities to T. urticae throughout the experiment with only 0.0-9.5% alive mites and 0.4% of eggs laid under leaf disc choice test.

Acaricidal and sublethal effects of tobacco leaf and garlic bulb extract and soft soap on Tetranychus urticae Koch. (Acari: Trombidiformes: Tetranychidae)1

Although the garlic bulb extract had the lowest toxic effect, its mixtures with the soft soap and tobacco extract showed higher toxicity against the adults, and it was determined that the tobacco leaf and garlic bulb extracts have potential to be used in the control of T. urticae fecundity.

JBiopest 8(2):68-81 (2015) Bioactivity of Leucaena glauca extracts on Tetranychus urticae © 475 Acaricidal and ovicidal efficacies of Leucaena glauca Benth. seed crude extracts on Tetranychus urticae Koch (Acari: Tetranychidae)

The preliminary screening under laboratory conditions is a great value for evaluating the acaricidal and ovicidal activities of hexane, dichloromethane and methanol crude extracts of Leucaena glauca

Toxic and repellent effects of Prunus laurocerasus L. (Rosaceae) extracts against Tetranychus urticae Koch (Acari: Tetranychidae)

The result indicated that seed extract of P. laurocerasus has good potential to be used to control T. urticae, however, the impact of these extracts on natural enemies of T. Urticae should also be needed further studies.

Acaricidal potential of some botanicals against the stored grain mites, Rhizoglyphus tritici

It was concluded that acaricidal potential of plants is directly proportional to time exposure and during first and second week C. fistula, S. aromaticum and C. longa proved to be more effective gainst stored grain mites as compared to the others plant extracts.

Acaricidal and repellent properties of some plant extracts against poultry red mite, Dermanyssus gallinae (Mesostigmata: Dermanyssidae)

It could be concluded that the aquatic and ethanolic extracts of C. erectus can be used as a safe botanical acaricide and repellent compound for control of D. gallinae in avicultures.

Acaricidal activity of Annonaceae fractions against Tetranychus tumidus and Tetranychus urticae (Acari: Tetranychidae) and the metabolite profile of Duguetia lanceolata (Annonaceae) using GC-MS.

The metabolite profile analysis of D. lanceolata stem bark suggested that the main constituents were 2,4,5-trimethoxystyrene and trans-asarone, and the stem bark was found to be the most active fraction against T. urticae .

Exploring genetic biodiversity: secondary metabolites from Neotropical Annonaceae as a potential source of new pesticides

The obtained results indicate that compounds from different chemical natures have a synergistic effect on the overall biological activity of the crude extracts, and argue for the use of Neotropical Annonaceae integrated pest management programs.



Acaricidal, repellent and oviposition deterrent activities of Datura stramonium L. against adult Tetranychus urticae (Koch)

Results suggest that D. stramonium extracts could be used to manage the two-spotted spider mite.

Toxicity of plant essential oils to Tetranychus urticae (Acari: Tetranychidae) and Phytoseiulus persimilis (Acari: Phytoseiidae).

Results indicate that the mode of delivery of these essential oils was largely a result of action in the vapor phase via the respiratory system, and merit further study as potential fumigants for T. urticae control.

Repellency and Toxicity of Extracts from Capparis aegyptia L. to Tetranychus urticae Koch. (Acari: Tetranychidae)

Ethyl acetate extract of leaves and fruits was the most potent extract tested against eggs and adult females of T. urticae Koch, and ethanol extract was the least effective extract against both tested stages.
