Effects of imidacloprid, dichlorvos, pymetrozine and abamectin, on life table parameters of the predatory bug, Orius albidipennis (Hemiptera: Anthocoridae)
Authors
Abstract:
تأثیر چهار آفت‌کش (ایمیداکلوپرید، دیکلرووس، پیمتروزین و آبامکتین) بر آماره‌های جدول زیستی سن شکاری Orius albidipennis (Reuter) مورد بررسی قرار گرفت. آفت‌کش‌ها در دزهای توصیه‌شده‌ی سازندگان مورد آزمایش قرارگرفتند. زیست‌سنجی با استفاده از روش قفس در شرایط کنترل‌شده‌ی C°1 ± 27 رطوبت نسبی %5 ± 65 و دوره‌ی نوری با 16 ساعت روشنایی در اتاقک رشد صورت گرفت. نرخ خالص باروری (Ro) در تیمار سن شکاری با آفت‌کش‌های ایمیداکلوپرید، دیکلرووس، پیمتروزین، آبامکتین و آب معمولی به عنوان شاهد به ترتیب، 48/0 ± 91/2، 55/2 ± 85/18، 21/1 ± 16/10، 05/1 ± 00/8 و 64/7 ± 40/43؛ نرخ ذاتی افزایش جمعیت (rm) به ترتیب 005/0 ± 040/0، 018/0 ± 097/0، 012/0 ± 086/0، 010/0 ± 078/0 و 006/0 ±148/0؛ میانگین طول یک نسل (T) 12/1 ± 60/25، 85/1 ± 94/25،25/0 ± 37/26، 21/0 ± 61/25 و 16/1 ± 20/25؛ مدت زمان دو‌برابر‌شدن جمعیت (DT) 76/2 ± 04/18، 60/1 ± 72/7، 11/1 ± 23/8، 37/1 ± 24/9 و 18/0 ± 68/4 و نرخ افزایش متناهی جمعیت (λ) 006/0 ± 041/1، 019/0 ± 102/1،013/0 ± 090/1، 011/0 ± 081/1 و 007/0 ± 160/1 برآورد گردید. در بین ترکیبات مورد آزمایش ایمداکلوپرید و دیکلرووس به ترتیب بیشترین و کمترین تأثیر زیان‌بار را بر شکارگر نشان دادند.

BACKGROUND The flower bug Orius sauteri is an important polyphagous predator that is widely used for the biological control of mites and aphids. However, the optimal conditions for mass rearing of this insect are still unclear, thus limiting its application. METHODOLOGY In this study, we investigated the optimal ingredients of an artificial diet for raising O. sauteri using a microencapsulati...

Commercial shipments of Orius spp. (Hemiptera: Anthocoridae) commonly include water and protein, the latter typically supplied by eggs from a moth such as Ephestia kuehniella (Zeller). To determine whether modified dietary conditions might improve predation, newly eclosed adult female Orius pumilio (Champion) were fed on E. kuehniella eggs plus encapsulated water, encapsulated 5% sucrose soluti...
