Functional response of the predatory mite Chileseius camposi (Acarina: Phytoseiidae) on densities of it prey, Panonychus ulmi (Acarina: Tetranychidae)

Functional response of the predatory mite Chileseius camposi (Acarina: Phytoseiidae) on densities of it prey, Panonychus ulmi (Acarina: Tetranychidae).

The functional response of the phytoseiid predator Chileseius camposi González y Schuster, 1962 (Acarina:Phytoseiidae) on densities of its prey Panonychus ulmi (Koch, 1836) was evaluated under controlled temperature (20 +/- 2 degrees C), relative humidity (75 +/- 15%) and photoperiod (16:8h L:D). A functional type II response was displayed (Holling's disk). Holling, Wolf transformation and Roge...

The influence of temperature on the functional response and prey consumption of Neoseiulus barkeri (Acari: Phytoseiidae) on Tetranychus urticae (Acari: Tetranychidae)

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 ...

A new species of chigger mite, Hannemania hegeneri (Acarina; Trombiculidae).

Evaluation of predatory mite (Acari: Phytoseiidae) releases to suppress spruce spider mites, Oligonychus ununguis (Acari: Tetranychidae), on juniper.

A laboratory trial evaluated four phytoseiid species for their potential as biological control agents of spruce spider mite, Oligonychus ununguis (Jacobi) (Acari: Tetranychidae). An augmentative biological control approach, using the predatory mites Neoseiulus fallacis Garman and Galendromus occidentalis Nesbitt (Acari: Phytoseiidae), was evaluated for reducing pest mite densities and injury, a...

the effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test

in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
