چکیده

بررسی و تعیین پارامترهای رفتاری و نوع واکنش تابعی یک شکارگر در انتخاب آن برای برنامه­ های کنترل بیولوژیک آفات دارای اهمیت است. در صورت کاربرد هم‌زمان شکارگر با یک بیمارگر حشرات، ممکن است واکنش­ های رفتاری آن دستخوش تغییرات شود. در این پژوهش، واکنش تابعی سن شکارگر (Orius niger (Hem.: Anthocoridae روی افراد ماده بالغ کنه تارتن دولکه­ ای (Tetranychus urticae (Acari: Tetranychidae سالم (بدون پاشش قارچ) و تیمار شده با قارچ بیمارگر Beauveria bassiana در چهار بازه زمانی صفر، 24، 48 و 72 ساعت و شاهد (تیمار با Tween80) در تراکم ­های مختلف 5، 10، 20، 30، 40، 50 و60 در شرایط دمایی 1±25 درجه سلسیوس، رطوبت نسبی 5±٦٥ درصد و دوره­ی نوری ١٦ ساعت روشنایی و ٨ ساعت تاریکی مورد بررسی قرارگرفت. واکنش تابعی سن شکارگر روی کنه ­های سالم از نوع سوم (III) و در سایر تیمارها واکنش تابعی نوع دوم(II)  تعیین شد.در مقایسه پارامترهای قدرت جستجوگری و زمان دستیابی شاهد با تیمارهای آلوده به قارچ بیمارگر در بازه ­های زمانی مختلف، فقط در پارامتر قدرت جستجوی شاهد با تیمار آلوده به قارچ در بازه زمانی صفر و زمان دستیابی در بازه زمانی 24 ساعت اختلاف معنی ­داری مشاهده نشد. در مقایسه پارامترهای سایر تیمارها با شاهد و با یکدیگر اختلاف معنی ­داری مشاهده شد. بیشینه نرخ حمله (T/Th) در دو تیمار آلوده به قارچ بیمارگر در بازه­ های زمانی 48 و 72 ساعت کاهش یافت و به همان نسبت زمان دستیابی افزایش پیدا کرد. این نتایج بیانگر تاثیر قارچ بیمارگر حشرات بر واکنش­ های رفتاری سن شکارگر O. niger می ­باشد.

چکیده [English]

Study of behavioral parameters and functional response of predators is an important process in selecting these agents for biological control programs. In case of simultaneous use of these predatory insects with entomopathogens, behavioral reactions of predator may be altered. In this study, type of functional response of the predator, Orius niger (Hem.: Anthocoridae) was determined on the healthy adult female mite, Tetranychus urticae (Acari: Tetranychidae) and on the Beauveriabassiana-treated mites atthe four time intervals 0, 24, 48 and 72 hours at different densities of 5, 10, 20, 30, 40, 50 and 60 at 25 ± 1 ° C, 65 ± 5% RH and 16:8h (L:D) photoperiod. The results showed functional response of this predatory bug on untreated mites was type III while it was type II in other treatments. Comparison of searching efficiency and handling time in control with fungus treatments at various time intervals was only non-significant between control and 0 hour in searching efficiency and between control and 24 hours in handling time post-inoculation. The maximum attack rate (T/Th) in two treatments of 48 and 72 hours was reduced and was significantly different from other treatments; concomitantly handling time of predator was increased. These results suggest the effect of entomopathogenic fungus on behavioral reactions of predatory bug, O. niger.
