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...
متن کاملEffect of Plant Materials on Developmental Periods of Two Spotted Spider Mite, Tetranychus Urticae Koch (acari: Tetranychidae)
Low concentration of raw flower juice of Calotropis porcera (Asclepiadecae) and seed dust of Nerium oleander (Apocynacae) significantly delayed the egg to adult development of two-spotted spider mite, Tetranychus urticae Koch, for three successive generations under laboratory trial. The flower juice of C. porcera was found more effective than the seed dust of N. oleander in delaying the develop...
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...
متن کاملResistance of 14 accessions/cultivars of Lycopersicon spp. to two-spotted spider mite, Tetranychus urticae (Acari: Tetranychidae), in laboratory and greenhouse
مقاومت چهارده رقم و لاین از گونه‌های مختلف جنس Lycopersicon نسبت به کنه‌ی تارتن دو‌لکه‌ای، Tetranychus urticae Koch، در آزمایشگاه و گلخانه بررسی شد. مطالعات آزمایشگاهی بر اساس دو روش زیست‌سنجی پونز (thumbtack) و دیسک برگی (leaf disk) صورت گرفت. گونه‌های Lycopersicon hirsutum و L. pennelii بیش‌ترین تعداد کنه روی پونز را داشتند. بیش‌ترین تعداد تخم (48/0 ± 15/5 تخم بر ماده در روز) رویL. pimpin...
متن کاملReproductive 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...
