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 ...

متن کاملControl 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...

رفتار کاوشگری دشمنان طبیعی به شدت تحت تأثیر دما قرار می‌گیرد. تأثیر دماهای مختلف بر واکنش تابعی و میزان شکارگری افراد ماده‌ی کنه‌ی شکارگر Neoseiulus barkeri Hughes با تغذیه از مراحل نمفی کنه‌یTetranychus urticae Koch ارزیابی شد. آزمایش واکنش تابعی برای افراد ماده‌ی بالغ کنه‌ی شکارگر در چهار دمای ثابت 20، 25، 30 و 1 ± 35 درجه‌ی سلسیوس و با استفاده از شش تراکم طعمه 2، 4، 8، 16، 32 و 64 فرد ...
متن کاملRepellent 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...
