چکیده

سفید بالک گلخانه و کنۀ تارتن دولکه­ای از جمله مهم‌ترین آفاتی هستند که به انواع گیاهان و محصولات گلخانه­ای را حمله می­کنند. کنۀAmblyseius swirskii  یک شکارگر عمومی است که می­تواند از هر دو این آفات تغذیه کند. در این بررسی میزان تغذیۀ این کنۀ شکارگر از مراحل مختلف رشدی هر یک از دوی آفت و ترجیح شکارگر بین مراحل مختلف رشدی هر یک از آفات و همچنین ترجیح غذایی و رفتار سوئیچینگ کنۀ A. swirskii بین مرحلۀ مرجح کنۀ تارتن دولکه‌ای و سفید بالک گلخانه در شرایط آزمایشگاهی (دمای ºC 1±25، رطوبت نسبی 10±70% و دورۀ نوری 16 ساعت روشنایی و 8 ساعت تاریکی) بررسی شد. نتایج نشان داد که پوره­های سن‌های پایین سفید بالک گلخانه نسبت به دیگر مراحل رشدی این آفت و مراحل متحرک کنۀ تارتن دولکه­ای، نسبت به مرحلۀ تخم ترجیح داده شدند. مقایسۀ میانگین شاخص بتای منلی در آزمایش ترجیح کنۀشکارگر بین پوره­های سن‌های پایین سفید بالک گلخانه و مرحلۀ پروتونمف کنۀ تارتن دولکه­ای نشان‌دهندۀ ترجیح کنۀ شکارگر برای کنۀ تارتن دولکه­ای نسبت به سفید بالک گلخانه است. نتایج به‌دست‌آمده از بررسی سوئیچینگ نشان داد که تغییر نسبت سفید بالک گلخانه و کنۀ تارتن دولکه­ای منجر به تغییر خطی مقدار β نمی­شود و رفتار سوئیچینگ در این شکارگر وجود ندارد. به‌عبارت‌دیگر بدون توجه به فراوانی نسبی کنۀ تارتن دولکه­ای و سفید بالک گلخانه، کنۀ شکارگر کنۀ تارتن دولکه­ای را به سفید بالک گلخانه ترجیح می‌دهد.

چکیده [English]

Greenhouse whitefly and two-spotted spider mite are two important pests on greenhouse crops. The polyphagous predatory mite Amblyseius swirskii preys on both of these pests. In this research, predation of the predatory mite on different stages of both pests, prey stage preference of pests, prey preference and switching behavior of predator between preferred stage of greenhouse whitefly and two-spotted spider mite were investigated in laboratory conditions (25 ± 1°C, 70 ± 10% RH and 16L: 8D hour photoperiod). The preference index for each experiment was calculated by Manly’s β index. Results showed that, young instars (first and second instars) of greenhouse whitefly and non-sessile stages of spider mites (larvae, protonymph and deuonymph) were preferred stages. Comparison of the mean preference index between young instars of greenhouse whitefly and protonymphs of two-spotted spider mite showed that this predator showed a significant preference to T. urticae. The variation in different ratio of preys had no effect on predatory mite preference so switching didn’t observed in A. swirskii.
