Control of two–spotted spider mite Tetranychus urticae Koch (Acari: Tetranychidae) by some selected chemicals

The experiment was conducted to study the effectiveness of four commonly used chemicals viz., deltamethrin, cypermethrin, malathion and sulphur against two-spotted spider mite (TSSM), Tetranychus urticae Koch on potted bean plants and on excised leaf discs. Mite population remained significantly lower in all treated plots except malathion treatment. The population of T. urticae differed signifi...

Reproductive parameters of Phytoseiulus macropilis (Banks) fed with Tetranychus urticae Koch (Acari: Phytoseiidae, Tetranychidae) in laboratory.

Predatory mites that belong to the Phytoseiidae family are one of the main natural enemies of phytophagous mites, thus allowing for their use as a biological control. Phytoseiulus macropilis (Banks, 1904) (Acari: Phytoseiidae) is among the main species of predatory mites used for this purpose. Tetranychus urticae Koch, 1836 (Acari: Tetranychidae) is considered to be one of the most important sp...

Pyrethroid Lambdacyhalothrin-Induced Population Increase of Tetranychus urticae Koch (Acari:

J. Agric. Entomol. l(}(3):197-203 (July 1993) ABSTRACT Based on data from apple trees without the presence of any predatory mites, the effect of the pyrethroid lambdacyhalothrin on population density of the twospotted spider mite, Tetranychus urticae Koch, is reported. Results show that significantly (P < 0.05) higher numbers of T. urticae were found in pyrethroid·treatcd trees relative to the ...

Mechanisms of resistance to organophosphates in Tetranychus urticae (Acari: Tetranychidae) from Greece.

We investigated the mechanisms conferring resistance to methyl-parathion (44-fold) and to methomyl (8-fold) in Tetranychus urticae from Greece by studying the effect of synergists on the resistance and the kinetic characteristics of various enzymes in a resistant strain (RLAB) and a susceptible reference strain (SAMB). It is shown that S,S,S-tributyl phosphorotrithioate, a synergist that inhibi...

Repellent effects of various cherry tomato accessions on the two-spotted spider mite Tetranychus urticae Koch (Acari: Tetranychidae).

Several studies have been conducted on resistance sources to improve the genetic resistance of farm-grown tomatoes to arthropod pests, including phytophagous mites. In the present study, we evaluate the behavior of the two-spotted spider mite on different cherry tomato accessions to identify possible sources of resistance (repellent effect) to this pest. Sixty-four accessions of cherry tomatoes...
