Life Tables of Two-spotted Spider Mite Tetranychus Urticae Koch (acari: Tetranychidae) and Its Predator Phytoseiulus Persimilis Athias-henriot (acari: Phytoseiidae)
Life table of Tetranychus urticae and Phytoseiulus persimilis on bean leaflets were studied under laboratory conditions in three seasons. For T. urticae the development time from egg to adult varied from 7 to 24 days and the highest immature mortality was 78.70 % in winter. Eggs laid by females were 88.1 eggs in autumn and 70.6 eggs in summer season. The gross reproductive rate (GRR) was the hi...
متن کاملAttraction of Phytoseiulus persimilis (Acari: Phytoseiidae) towards volatiles from various Tetranychus urticae-infested plant species.
Plants infested with the spider mite Tetranychus urticae Koch, may indirectly defend themselves by releasing volatiles that attract the predatory mite Phytoseiulus persimilis Athias-Henriot. Several plants from different plant families that varied in the level of spider mite acceptance were tested in an olfactometer. The predatory mites were significantly attracted to the spider mite-infested l...
متن کاملLife Table and Predation Capacity of Phytoseiulus persimilis Athias-Henriot (Acari: Phytoseiidae) Feeding on Tetranychus urticae Koch (Acari: Tetranychidae) on Rose
The life history and predation rate were determined for all stages of female and male of Phytoseiulus persimilis Athias-Henriot fed on the eggs of Tetranychus urticae Koch ˗ as the preferred prey-stage ˗ on rose (cv ‘blarodje’) leaf discs under laboratory conditions at 25±1°C, 75±5% RH, and 16 L: 8 D hour photoperiod. According to the age-stage, two-sex life table model, the intrinsic rate of i...
متن کاملEvaluation of a mechanical dispenser and interplant bridges on the dispersal and eYcacy of the predator, Phytoseiulus persimilis (Acari: Phytoseiidae) in greenhouse cut roses
Adequate distribution of natural enemies is necessary for successful augmentative biological control. In California greenhouse cut roses produced using the bent shoot system, the predatory mite Phytoseiulus persimils is widely used for control of the phytophagous mite Tetranychus urticae. One purported advantage of the bent shoot method is that the dense foliage of the lower canopy creates inte...
متن کاملبررسی اثر رایحه های القایی چهار رقم لوبیا بر جلب کنه شکارگر (Acari: Phytoseiidae) Phytoseiulus persimilis،
اگر چه مقاومت ژنتیکی ارقام گیاهی مطمئن ترین، سالم ترین و ارزان ترین روش کنترل آفات محسوب می شود ولیکن در مدیریت تلفیقی موفق آفات، ارقام گیاهی مقاوم به آفت بایستی با عوامل کنترل بیولوژیک سازگار باشند. در تحقیق حاضر میزان جلب کنه شکارگر، Phytoseiulus persimilis، و همچنین میزان تولید رایحه های القایی، که عامل جلب کنه شکارگر به گیاه هستند، در 4 رقم لوبیا (ناز، خمین، اختر و G11867)، پس از آلودگی به ...
