Chemosterilization of the Two-Spotted Spider Mite. I. Effect of Chemosterilants on the Biology of the Mite1

Journal of Economic Entomology, 1969
The effect of the chemosterilants apholate, tepa, 5-fluorouracil, and 5-fluoroorotic acid on Tetranychus urticae Koch was studied. Sterility was induced in T. urticae by all 4 chemosterilants, although the extent of sterility was dependent on the concentration and mode of application of the chemosterilant and the sex, stage of development, and age of ...

Toxicodynamic mechanisms and monitoring of acaricide resistance in the two-spotted spider mite

Pesticide Biochemistry and Physiology, 2015
The two-spotted spider (Tetranychus urticae) is one of the most serious pests world-wide and has developed resistance to many types of acaricides. Various mutations on acaricide target site genes have been determined to be responsible for toxicodynamic resistance, and the genotyping and frequency prediction of these mutations can be employed as an ...

Control of Two-spotted Spider Mite by Phytoseiulus persimilis

Journal of Asia-Pacific Entomology, 2001
Abstract Two-spotted spider mites, Tetranychus urticae Koch have been a problem for many years. A broad approach to population management is needed. – Hybridization between greenhouse strains of T. urticae and introduced strains may result in a strain with different life-history traits.

Acaricidal activity of spinosad and abamectin against two-spotted spider mites

Experimental and Applied Acarology, 2007
Spinosad is a bioinsecticide with a high degree of selective toxicity towards insects of different orders, but its toxicity towards the two-spotted spider mite (TSSM), Tetranychus urticae Koch (Acari: Tetranychidae) is under debate. In this study, we compared the acaricidal properties of spinosad with the commercial bioacaricide abamectin on the life ...

Two-spotted spider mite in Cyprus: ineffective acaricides, causes and considerations

Journal of Pest Science, 2008
Growers of greenhouse roses in Cyprus have recently reported failures of several acaricides against two-spotted spider mite (Tetranychus urticae Koch). To verify the cause of these failures we evaluated the effectiveness of seven acaricides against two rose and two cucumber spider mite populations in the laboratory. The acaricides included in our study

Properties of partially purified malathion carboxyesterase of the two-spotted spider mite

Journal of Insect Physiology, 1965
Abstract The malathion carboxyesterase found in a multiple organophosphate-resistant strain of the spider mite was purified about eightyfold and characterized. It was shown to have hydrolytic activities against malathion (carboxyesteratic as well as phosphoroesteratic), malaoxon, parathion (phosphoroesteratic), and a number of naphthyl and ...

Preparation and characterizations of essential oil and monoterpene nanoemulsions and acaricidal activity against two-spotted spider mite (Tetranychus urticae Koch)

International Journal of Acarology, 2018
The present study aims at preparing nanoemulsions of two types of plant essential oils (EOs) (Callistemon viminalis and Origanum vulgare) and two monoterpenes (R-limonene and pulegone) as acaricidal agents against two-spotted spider mite, Tetranychus ...

Biological responses of the two-spotted spider mite, Tetranychus urticae to different host plant

Archives of Phytopathology and Plant Protection, 2019
This study investigated the development, reproduction and life-table parameters of the two-spotted spider mite Tetranychus urticae (Koch) (Acari: Tetranychidae) reared on beans (Phaseolus vulgaris), cucumber (Cucumis sativus), eggplant (Solanum melongena)
